Vacuum furnaces with gas hardening

Vacuum furnaces with gas hardening

Vacuum furnaces with gas hardening are used for hardening of high speed steel tools, controlled hardening of tool and other alloy steels.

  Ultimate vacuum Pa   0.001
  Maximum overpressure, bar   6/10/12/16/20
  Working area, (WxHxD), mm   from 200x200x400 to 900x900x1500
  Mass of the loaded cage at the same time, kg       from 30 to 1200


Description:

The furnaces have a convection heating function, which can be realized not only as stepwise isothermal quenching, but also quenching, annealing, carburizing, nitriding and other heat treatment processes.

The furnaces are controlled by a programmable logic controller. The temperature in the furnaces is maintained with high accuracy by a separate controller. Furnaces have a high level of automation. During operation, the operator can safely switch from automatic to manual control mode, the furnaces are provided with an emergency warning system.

The ovens are easy to set up, operate and maintain. When designing this series of ovens, our designers paid special attention to ease of maintenance, reduced energy consumption, environmental protection and increased productivity.

 

Design features and equipment:

 

  •      Water cooling of the furnace body and door, current leads and cooling gas circulation pipes. Gas cooling system with powerful fan and water heat exchanger.
  •      Heating chamber of square or round section.
  •      Thermal insulation and heaters made of graphite.
  •      Autoclave type oven door with pneumatic blocking.
  •      Sealed connector for connecting up to 12 thermocouples in the furnace.
  •      A large set of additional components at the discretion of the customer.
