Definitions
- the advantage of the method according to the invention and the device for carrying out this method is, above all, that the cooling rate of the HIP material can be controlled within wide limits and can thus be adapted to the requirements.
- the heat accumulator can easily be adapted to the conditions by increasing or reducing its mass. This adjustment of the cooling rate leads to a significant improvement in the quality of the HIP material and, above all, to a considerable saving in energy.
- the occupancy time of the HIP furnace can also be significantly reduced, which leads to better utilization of the system.
