Vacuum furnaces


For highest demands in heat treatment processes regarding distortion, decarburization, no oxidation and repeatable results.

 

System characteristics:

  • Optimized temperature homogeneity
  • Homogeneous quenching effect –low distortion –in the whole working chamber due to routed reverse cooling system
  • High performance turbine with variable power
  • Step-quenching
  • High efficiency isolation and heating made of graphite
  • Easy to maintain, no transport of load, no vacuum locks
  • Cost-saving and rapid maintenance due to optimized design of system
  • Little space required
  • Convective heating for reduction of process time and tempering processes
  • Meets the NADCA recommendation 207-97 for heat treatment of 1.2344 (AISI H13)

 

Advantages of process:

  • Precise process control due to various batch and control thermocouples on the workpiece
  • Optimized gas flows
  • Use of state-of-the-art control and feedback control systems for customer specified processes
  • Partial pressure system for high temperature ranges
