Dual chamber high temperature quenching furnace

First, double-chamber box quenching furnace use

Dual-chamber box quenching furnace, mainly used for high-alloy products, tool steel, high-speed steel, stainless steel high-pressure gas quenching and low temperature alloy magnetic materials, such as vacuum annealing, vacuum sintering can also be used for powder metallurgy, stainless steel brazing and copper Brazing and so on.

Third, double-chamber box high temperature quenching furnace standard structure

1, the vacuum furnace host horizontal single-chamber structure, the furnace, furnace cover, heating room and forced circulation air-cooled devices and other components.
2, the furnace body and lid for the double-wall water-cooled structure, the inner and outer walls made of carbon steel. There is a gap between the two layers, with cooling water inside. The front end is connected with the flange of the furnace mouth, the back end is connected with the sealing head, and a flange interface connected with the air cooling motor is left at the rear end of the furnace body. In the lower part of the furnace body is designed to support the furnace body, in order to display the furnace body.
3, the seal between the furnace and the door design for the lock ring two-way seal, the seal ring installed in the furnace flange groove, you can guarantee the vacuum furnace in negative pressure and high pressure air-cooled seal.
4, heating room by the insulation layer, heating elements, material Taiwan and other components.
5, in the back of the vacuum furnace equipped with high-flow rate blower and heat exchanger and other components of the rapid cooling system.
6, inflatable system: from the gas tank demand side, large diameter special pneumatic valve, valve trim, manual valve.
7, before the heat exchanger with a deflector, (my company recently introduced circular radiator, cooling area greatly enhance the cooling rate) to make the gas flow smoothly.
8, vacuum system: vacuum system consists of rotary vane pump, Roots pump, diffusion pump, installed in the evacuation pipe vacuum valve, pressure valve, flexible connectors and other accessories in the composition of the vacuum machine. The ultimate vacuum of up to 6.6 × 10-3Pa.
9, inflatable system: from the gas tank, large diameter special pneumatic cut-off valve, trim valve, manual switch, solenoid valve and other components can be achieved quickly to fill gas to meet the requirements of quenching process. The system also adjusts and controls the degree of vacuum in the furnace.
10, the electrical control system: The system consists of voltage regulator, SCR and temperature programmable controller composed of temperature programmable control by the PLC and the mechanical action programmable control of two parts, enabling automated program operation , And both manual functions.
11, the temperature controller with intellectual temperature controller, temperature control accuracy, and PID parameters from the stability of the function
12, programmable logic controller for mechanical movement control, can realize the time, open the valve, out of material and other movements of all automatic control.
13, the control cabinet is equipped with large-scale mode industrial computer, can visually display the working status of the stove, and can be manually operated by the button.
