High vacuum furnace for tempering

appointment

High vacuum furnace for tempering is intended for release of tool steel, stamped steel, high speed steel, high-strength steel and titanium alloys after hardening and sintering under vacuum to leave and aging products from ferrous metals after recrystallization.

Technical features

1. Vacuum furnace for tempering is a horizontal, single-chamber with horizontal loading. Options for opening the oven door on request.
2.Kamera furnace consists of heaters nikelhromovyh alloys and multilayer reflective screens of stainless steel products for thermal insulation, with good temperature uniformity and homogeneity of the cooling.
3.Polny products leave the process under high vacuum after the processing of surface light, without color changes.
4.Vnutrenny exchanger high-vacuum furnace for tempering and the circulation system of rapid cooling gas can effectively prevent brittleness after tempering.
5.Ustroystvo provides convection heating temperature uniformity in a heating chamber at a low temperature.
