HAYES INC. 800 _Wellington Avenue, Cranston, RI 02910 401-467-5200 80 Years As The Leader With a long and impres- sive list of heat treating equipment "firsts" to its credit, C.I. Hayes Inc. of Cranston, RI is a recog- nized leader in the design and manufacture of heat treatment .furnaces. Founded in 1905 by Carl I. Hayes, a registered electrical contractor, the business was created to meet a challenge to pursue the PQtentials of industrial · electrical heat treating. Cleanli- ness, control and uniformity of heat distribution, ease of applica- tion, .flexibility in design, and · economy of operation, were the desired properties which electric- ity seemed to offer. From Mr. Hayes' accep- tance of that initial challenge, Cl Hayes Inc. has been in the fore- front of industrial heat treating progress. Within a short time Hayes developed the first el~tric heat treating furnace. In the intervening years the company has maintained that pioneering spirit with an accompanying creative ability and has received 50 U.S. patents and numerous interna- tional patents. · Rapid industrial develop- ment in the early 1900's led to high technical standards in the field of furnace construction and An.

Refinements derived from a continuing research of this damage · culminated when Hayes perfected and sold the first "Certain Curtain" controlled atmosphere furnace in 1927. The company also deve~- oped the fll'st bright hardening furnace for stainless steel in the 1930's and sold the fll'st commer- cially successful Humpback furnace. Firsts From Hayes . . . .. Other Hayes Company accomplishments include: First silver deposition on glass First dual atmosphere process First "no muffle" furnace First molecular sieve dryer First combination hydrogen generator and high pressure dissociator During the 1940's, Hayes established a combined Research and Development Laboratory and commercial heat treatment shop. This multiple use facility provided a place where industry could bring heat treating problems to be solved by resident experts and view operating equipment under typical working conditions. Hayes has always worked closely with industry, developing special equipment for their needs. C.I. Hayes Inc. prides itself on the fact that it holds a leadership position in the industry not only in equipment design but also in process innovations. ~eflecting the high priority placed on research and , development was the company's ability to provide the Raytheon Company with the first commer- cial vacuum furnaces • ... where ideas in Heat Treating Equipment begin! ;2._ 0.f-;;20 I l~I"' _________________________________________ _ . . - a· !:/:· .. ~: ~:-· ~ '·t-: rtt I ··.·· , . .... . :· (') .. · N, •, *.~ r-.+-tt-11t"-:8\ -++-----1"1 .:· ' ... + _;t·.,. -:.+ -t-. : +·. .....

Hayes Inc. straight through conveyor furnace and an atmosphere generator combination unit. A description of the construction, controls, and special features follows: Our terms and conditions form includes delivery, start-up, installation responsibility and warranty applied to this equipment. GENERAL DESCRIPTION; The equipment includes an insulated heating chamber, muffle, cooling section, work tables, conveyor and integral atmosphere generator. All controls and instrumentation are "built-in" to form a single free standing package. The combination represents to the purchaser prov.en designs applied specifically to his requirements. FURNACE SPECIFICATIONS; ~L The enclosure for the heating chamber will be constructed of heavy gauge fabricated steel sheets. It will be properly reinforced internally to give a clean line appearance. The shell construction includes access covers or terminal guards for the heating element terminal area. Natural convection terminal cooling is achieved by properly placed vent openings. A removable top cover allo~s internal maintenance. INSULATION; Properly graded multiple courses of high quality refractory and insulation have been selected to minimize normal heat losses from the work chamber·, reducing power consumption. Selection of materials is based on refractories, strength at temperature and durability when exposed to the surrounding conditions. Quality, economy and experience are combined to present to the purchaser the finest insulation characteristics. Relationship between height, width, length of chamber and location of heating source for temperature uniformity and distribution have been carefully engineered~ · -1- 0 OF d-0 C.I. HAVES INC. _,. -·~ HEATING EI,fflENT8 ; Twenty-four (2l.i.) ceramic elements are the heating source. These are specifically designed with low watt density and high cross section to give extended life at higher temper~tures and atmosphere conditions encountered in a sintering furnace. The heating elements are mounted transversely-above and below the work area.· This design permits easy replacement of elements when required. The elements are carefully graded and selected for matched resistance values for each circuit. FRONT AND REAR THROAT; Throat areas will be designed to minimize heat losses by radiation. These areas are also designed to provide easy access to, or removal of, internal components. Stainless steel adaptor plates provide the usual clean appearance. CONVEYOR BELT; A properly selected alloy wire mesh conveyor belt designed to process the specified load will be used. The alloy is chosen according to temperature and atmosphere conditions. The mesh is chosen according to the method of loading or physical size of the work pieces. The above combination dictates the most economical belt. CONVEYOR DRIVE; A variable speed drive assist the_purchaser in the deterrnin,ation of the proper conveyor speed for the processed work. Automatic belt take-up is accomplished by the suspended catenary method. With this method, expansion and application of belt tensions are controlled to give maximum effective belt-driving transmission. An electronically controlled DC.drive motor, speed reducer, sprocket and pulleys complete the drive system. Belt speed ranges have been selected to meet the purchaser's requirements. -2- 7 cF ;;)..O C. I. HAVES INC. •· :.:. MUFFLE: An Inconei muffle will be provided in the furnace section. It will extend from the front tunnel to the cooling section. In order to· maintain the lowest dew points possible while the work parts are being heated, the muffle will be completely heli-arc welded. This is all designed for conservation of atmosphere. As a bonus, furnace "conditioning" is speeded up thus allowing for more productiol'!-time. *The floor of the muffle will be completely lined with formed Inconel Superhearth Plates. The presence of the plates will eliminate any thermal shock effect on the muffle from the cool work and belt entering the furnace. COOLING-SECTION; A water-jacketed cooling tunnel extends from the insulated cooling section to the exit vestibule. The modulation of the cooling water will be regulated through manual control valves. An open sight drain will be provided so that water flow can be easily adjusted if ever the factory pre-set adjustment requires changing. The cooling section is rated at 5 psi maximum and no valve or restriction should be used on the drain line. The cooling water will be clean enough to ·use in other processes, if required. EXIT VESTIBULE; There will be hanging curtains in the exit vestibule so that a flame curtain will not be necessary. Light delicate work, once cooled, will not be reheated. The curtains will also provide economy of atmosphere yet will be light enough not to injure the most delicate work. FRONT ANP REAR TABLES; At the front of the furnace will be a loading table straddling the belt for convenience. It will also support the idle roll. The rear or unloading table will also straddle the belt and act as support for the drive mechanism. An added feature is the cantilevered tables for the convenience of the operator. *Super Solitaire Models Only -3- C. I. HAYES INC. AMMONIA DISSOCIATOR SPECIFrc,n;fONS; SHELL; / In the same shell as the furnace, will be an integra-~onia ·ssociator. It has been ~elected to provide an economical source of an xceptionally dry atmosphere for the work while it is being heated and c~9led. Dissociated ammonia is composed ~f-75% hydrogen (very reducin' and 25% nitrogen (inert) and will /have a dew point of minus 50°F if t ammonia used is "Metallurgical/grade". This dew point is more than a ate to produce bright work and minimize the use of flux. Dissoci ors are very simple, g.ei>endable and trouble-free. They have no mov parts to wear ou~ need a minimum of maintenance and require very li: :tle oper~tor skill. ,,A/ Of U'C::::Ef'\ INSULATION; / v J J_) The same quality insulatio~ in the furnace. // HEATING ELEMENTS; / Similar and as ea~y to service as in the furnace. The same special ~J:It('tiles are used. RETORT AND CATALYST; / The diss'ociating retort will be a multipass, orizontal loop tube type.,.const:ructed of Inconel and hermetically s aled by heli-arc welding. The retort will be filled with a speci l catalyst to aid in _,,.dissociation. /' . CONTROLS; POWER CONTROL; All controls will be of high quality and will all be front panel mounted, for ease and simplicity. There will be an "OFF-ON" switch controlling both temperature indicator controllers which will hold the temperature of each unit to within very close limits. The controllers are very simple to set and very easy to read. Both instruments will have a temperature control set point but will also have a second interlocking set point for atmosphere control. These interlocks control an ammonia solenoid valve so that ammonia will not be admitted to the·dissociator if it is not up to temperature and atmosphere will not be admitted to the furnace if it is not up to lq.QQ°F. -q.-q oF ;J.o , ______________________________________ _ C. I. HAVES INC. This system provides reliability as well as eliminating costly nitrogen purging Both instruments will have thermocouple burn-out protection. The furnace is further protected against failure by an alarm system that will sound in the case of a seized contactor. BELT SPEED CONTROLS; Conveyor speed control will be front panel mounted· and provide speed change potentiometer. FINISH; The furnace will be completely finished and painted to provide a pleasant appearance. All materials supplied will be of finest quality and assembled with fine craftsmanship synonymous with the Hayes tradition since 1905. This system has been specifically designed for simplicity and economy of installation, operation and maintenance. -5- 10 OF ;;20 C. I. HAVES INC. SPECIFICATIONS Model: Maximum Operating Temperature:.

NITROGEN PURGE SYSTEM In order to provide protection from loss of atmosphere and adequately shut down furnace operation due to power failure, we are submitting the following automatic purge system for your consideration and eval uatio:i;i. · Incorporation of the NPS system will ensure continual monitoring of the atmosphere system with or without the presence of an operator. The system will be supplied complete with all components mounted and wired on the furnace and control panel. Connection to the required utilities is all that will be required to make the system operational. The automatic purge system is designed to help the furnace meet cur.rent safety standards as adapted by the United States government. Although the equipment is available without the purge system, the purchase of the system is highly recommended as a means of ensuring proper start-up and shut down procedures and protection from malfunctions as follows: M1\LFQNCTION A.

I I I I I I I N9 I I I I I I .. I I DESCRIPTION-OF THE MSA-60 Th~ Hayes Molecu-Oryer'" consists of two adsorption chambers mounted on a base and encased in a ventilated metallic housing. The adsorption chambers are made up of welded steel construction and a~e provided with electric heaters. The chambers are filled with Linde'" Molecular Sieve adsorbent through the openings provided fnr this purpose in the top of the chambers. The tops of the two adsorption chambers are piped to a common inlet with two solenoid valves controlling gas flaw. The actuation of the valves is controlled by a cam timer. The bottoms of the chamber~ are piped together through check valves to a common outlet, and the outlet is provided with a relief valve. The tops of the absorption chambers are also piped together through solenoid valves which automatically open the chambers to atmosphere for venting and automatically close in the sequence required. The electrical circuit consists of two heaters, one for each adsorption chamber, magnetic switches, indicating lights, and an electric cam-type timer. Once the dryer is started it will operate completely automatically, changing the flow of gas from one adsorption chamber to the other and reactivating saturated chambers at set intervals of time.

A bypass shau 1 d be installed around the dryer to allow for repairs with no interruption of atmosphere fl ow. Provide an inlet with a test cock for measuring the dew point of the entering gas. Connect the outlet of the dryer to a dry gas manifold. Also make provisions for testing the dew ~oint of effluent gas. Ory pipes thoroughly before installation. Make the electrical connections ta the terminal provided. The customer must supply a power line service switch in the supply line. If the dryer is to be used for combustible gases, pipe the vent to a nonhazardous location. A drain ~alve or petcock should be provided at the lowest point in the vent line io that any condensed moisture can be dra~ned periodically to prevent moisture from flowing back into the regenerated bed. Provisions should also be made for purging the dryer and associated piping during the initial start up •. In selecting piping, especially dry gas p1p1n9, u~e a very clean pipe or tubing. Take ~xtreme care not to entrap any moisture or use Jointing compounds that contain moisture. ( 14) · I 5. •• I I I I I I I _,. I I I I I I •• I I OPERATION 5.1. Adsorption ..; The ~as to be dried enters the dryer at the gas inlet, passes through an 'fn 1 et va 1 ve, and enters the molecular sieve desiccant area where it is to be dried or have other impurities removed. The g~s then exits through the corresponding check valve and passes out to process. The adsorption in one chamber continues for an eight hour period. Regeneration _ Immediately after adsorption begins in one chamber, regeneration automatically begins in the other. A heater is energized by a cam timer setting. A pilot light and its corresponding vent solenoid valve are simultaneously energized at this time. A small· quantity of the dry gas is passed through a bypass control valve and enters the heated chamber. The gas carries the released moisture from the sieve out through the vent to waste, It should be noted that the flaw of this purging gas is opposite to the flow of the gas being dried. The timing cams are set so that the heaters, pilot light, and purge solenoid valve shut off after 2-1/2 hours~ 5.3. Operating Instructions Dryers used for drying .Q..Qll.-COmbustible gases may be connected to the power and gas supply as instructed in the installation section o,f' this manual, electrically energized, and used for t~e desired purpose. Dryers far combustible gas must be purged on the initial start-up prior to placing the dryer in operation. The purge must include associat*d piping as well as the dryer chambers. For t-h is reason, the i ne-rt gas supp 1 y shou 1 d be connected into the dryer's piping at or near the ~ombustible gas supply sourc~. The recommended purge procedure is as follows: ·1_ Check that the electrical power to the dryer has been turned off. 2 Open the control panel door and disengage the timer motor and drive gear. . 3 Rotate the timer's index wheel to the 11 20 11 position. 4 C)ase the control panel door, turn on the electricai· power ta the dryer and open the purge iupply valve. A recommended purge is 20 volume changes for each chamber, _ 5 In order to purge the other chamber, turn off the electrical power to the dryer, open the control panel, and rotate the index wheel to the "70" position. (15) / 9 a-F;lo I •• I I I I I I I ti• I I I I I I •• ·1 I 6 7 8 9 10 11 Close the control panel door, turn on the electrical power, and open the purge supply valve. Close the purge supply valve when the purge is completed. Check that the power is off, open the control panel door, and set the timer index wheel at "O". Engage the timer motor and drive gear, close the panel door, -open the combustible gas (process gas) supply valve and turn on the electrical power. Immediately following the commencement of the cycle (before any heating effect of the sieve is felt), set the purge flow rate to 6 scfh (see flow diagram drawing). Then tighten the package gland on the needle valve, remove the valve handle, and disconnect and remove the flow meter. Positive gas pressures must be maintained on the dryer wh i 1 e a chamber is undergoing react i v·at ion to insure the proper bypas, flow. Lack of pressure while a chamber is heating may r~sult in overheating of the sieve and destruction of its ability to remove moisture. Lack of pressure while a·heated c.hamber·is cooling may create a vacuum in the chamber. (16) · ~O oF;;)o .... ~·- ! i •: I I ! I I I l ~ i ! t l ,: l . i/ Professional Service Industries, Inc.
