Well quenching furnace
RJ2 series pit-type quenching furnace is a national standard energy-saving cycle-operating pit-type furnace. The heat treatment or quenching temperature is 850-1200 ℃. It is mainly used for quenching metal parts and mechanical parts such as shaft workpieces, rod-shaped workpieces, rolls, 45 steel, stainless steel For heat treatment, vertical hoisting and quenching heating, the workpiece is not easy to deform, and mechanical parts can also be annealed and normalized heat treated.
The shell structure of the well type quenching furnace is made of steel plate and section steel with a cylindrical furnace body. The furnace lining is built with ultra-lightweight energy-saving thermal insulation bricks. The furnace lining and the furnace shell are sandwiched by an alumina fiber blanket for insulation. The resistance wire is installed in the furnace with 0Cr27Al7Mo2 high resistance alloy wire or resistance tape. Firstly, it is arranged by the uniform temperature cloth method, and it is divided into multi-zone and multi-stage design from top to bottom, and then the temperature of each zone in each zone is controlled by microcomputer program technology with high precision. The design is reasonable, the temperature in the pit furnace is uniform, and the temperature control accuracy reaches ± 1 ℃. The well type quenching furnace is equipped with an automatic temperature control cabinet and a thermocouple when it leaves the factory. It can also be equipped with a well type tempering furnace and quenching tank to form a well type heat treatment furnace production line.
1 Reasonable structure design, uniform furnace temperature, small temperature difference between the upper and lower working areas, especially suitable for heating and heat treatment of shaft-shaped long workpieces.
2 Using energy-saving furnace lining, fast heating, small loss of empty furnace, more than 20% energy saving of older products.
3 There are two types of furnace cover: open type and integral type. The workpiece can be hung inside or outside the furnace. Convenient for users to choose according to different needs.
4 The control system can be equipped with conventional control instruments or instruments with microprocessor program control as required.
5 When the process requires, a protective atmosphere can be introduced into the furnace to achieve less oxidative heating.
6 Each product is equipped with a safety interlock and over-temperature protection device, which is reliable and safe in operation.
7 Different well heating furnaces, tempering furnaces, quenching tanks, cleaning machines, etc. can be selected to form a well heat treatment furnace production line, which can expand the scope of application and production capacity of the furnace.
