Gas fired furnace requirement Inquiry (采购产品): Gas fired furnace requirement Wednesday, November 24, 2004 TO, L & L SPECIAL FURNACE CO. INC. Dear Sir, One of our loyal costumer is interested to buy the following specification furnaces , We are the leading furnace manufacturer since last 15 years & we are interested to make a technological tie up for manufacturing the same furnaces. We have all necessary state of the art furnace manufacturing facility with modern AUTO CAD designing & communication facility. kindly send us the offer for the following specification furnace & to make a tie up for the above said manufacturing the furnace on long term basis please contact us. Best Regrds PRAKASH MALADKAR MANAGING DIRECTOR AFECO HEATING SYSTEMS PLOT NO. F-23, MIDC AREA GOKULSHIRGAON KOLHAPUR.416234 PH:-00-91-231-2672620 , FAX :-00-91-231-2672461 E-mail:-kpr_maladkar@sancharnet.in FURNACE REQUIREMENT DETAILS ARE:- For our seamless refillable cylinders manufacturing plant, we need a continuous hardening/quenching & tempering furnace as . 1. Fuel will be LPG. 2. The diameter for cylinders will be 233 to 356 mm 3. The length of cylinders will be 600 to 1500 mm. 4. Capacity maximum 65 cylinder per hour. Hardening furnace Purpose : For heating the cylinders to hardening temperature of max. 950O C for the hardening and tempering process. (material : 30 Cr Mo 4/34 Cr Mo 4) For normalizing the cylinders at a temperature between 870O C and 900O C. (material : 36 Mn 4 / ST E 355) The furnace should have the following features : 1. Adjustable material flow rate. 2. Two temperature regulating zones with registering the furnace temperatures. 3. Slight overpressure against infringement of cold air. 4. Manually actuated door pushing device at inlet side. 5. Optical barrier controlled, door pushing device at the outlet side for automatic 6. Easy access for inspections Quench basin with immersion unit The immersion unit has to be designed such that the immersed cylinders can be lowered (swung) in the oil bath during quenching in order to prevent blistering and, thus, defects in hardness. The immersion time shall be adjustable between 0.5 and 9 minutes. After the quenching process there must be the possibility to drain off the oil before the work pieces are transported to the tempering furnace. The immersion unit for quenching can be designed according to the choice of the furnace manufacturer for a vertical or a horizontal cylinder arrangement. Immersion unit shall have suitable cooling arrangement. The immersion unit and transfer unit to the tempering furnace have to be designed such that during the process "normalizing" the cylinder transport for cylinders made of material 36 Mn 4 and ST E 355 can be effected directly from the hardening furnace, to the tempering furnace, (bypassing immersion process.) Tempering furnace The furnace has to be designed for a controllable tempering temperature up to max. 700O C and should be equipped with manually actuated door pushing devices at both sides. During the heat-treatment "normalizing" the furnace is not heated, i.e. the transporting unit of the furnace merely serves as further transport of the cylinders. **** Hidden Message ***** Prakash Maladkar F 23, MIDC AREA GOKULSHIRGAON INDUSTRIAL AREA KOLHAPUR.416234 IND Company: AFECO HEATING SYSTEMS PVT.
