Net back furnace

Tempering furnace for general metal parts in the air tempering and aluminum alloy die-casting parts, piston, aluminum plate and other light alloy parts quenching, annealing, aging heat treatment. The shell is welded by steel plate and section steel, and the trolley is welded by section steel and plate. The trolley can reduce heat radiation and convection loss through soft contact with the furnace lining and sand sealing mechanism to effectively ensure the sealing of the furnace body.

Tempering furnace is a periodic operation tempering furnace, which is used for tempering general metal parts after quenching and quenching, annealing and aging heat treatment of light alloy parts such as aluminum alloy die-casting parts, pistons and aluminum plates.

Type of tempering quenchability of tempering furnace

270℃~350℃ embrittlement: also known as low temperature tempering quenching, mostly occurs in carbon steel and low alloy steel.

400℃~550℃ embrittlement: Usually alloy steel for construction is prone to embrittlement at this temperature range.

475℃ embrittlement: especially refers to the Cr content of more than 13% of the granulated iron series stainless steel, tempered between 400℃ and 550℃, resulting in increased hardness and embrittlement phenomenon, especially at 475℃.

500℃~570℃ embrittlement: common in the processing of tool steel, high-speed steel and other materials, at this temperature will precipitate carbide, resulting in secondary hardening, but also lead to increased brittleness.
