Application
It is used for vacuum aging and re-crystallize annealing after solid solution of tool steel, die steel, high speed steel, super high strength steel, stainless steel, high temperature alloy Ti alloy and etc.
Technical Features
1. Horizontal, single chamber, loading horizontally. The way of opening door is optional according to customer’s requirement.
1.All metal hot zone, good temperature uniformity.
2.Aging at high vacuum, the part is bright and without color change.
3.The fast cooling system composed of inner heat exchanger and gas cooling circulation can effectively prevents components from tempering brittleness.
4.It has convection heating device, which can ensure the temperature uniformity at the state of low temperature.
5.It has rapid cooling using copper fin heat exchanger and blower, optional of internal circulation and external circulation.
