Features：

- The protective gas chamber tempering furnace has a high temperature range of 600 ∽ 1200 ° C and can be used under nitrogen, hydrogen or argon atmosphere, and can be used for heat treatment of metal parts or sintering of hard materials at high temperatures.

Features of the protective gas chamber tempering furnace:

1. The special structure makes the surface of the heated steel piece not decarburized, non-oxidized, and the surface is bright and clean after quenching;

2. Power saving, saving time and convenient use;

3. The electric furnace has good sealing performance and is safe and dangerous.

- The protective gas chamber tempering furnace shell is made of national standard steel plate and section steel. The furnace lining is made of ultra-lightweight high-alumina energy-saving insulation brick, combined with aluminum silicate fiber cotton composite lining insulation. The electric heating elements of the box type tempering furnace are made of long-life design and high temperature resistant high-pressure 0Cr25Al5, which are arranged on both sides of the furnace and the bottom of the furnace. The furnace door is electrically or hydraulically lifted, and the small box type tempering furnace can also use the hand crank door. When the furnace door is opened, the circuit breaker protection device stops the power transmission and heating. The microcomputer temperature control system is used to control the tempering process with high precision, and the whole process of tempering heat treatment from furnace to furnace is fully automated.
