Hight temperature conveyor belt heat treatment furnace for knife

The continuous atmosphere protective bright quenching heat treatment furnace is mainly used for stainless steel knives and forks treatment. After the product is treated by the equipment, the surface is bright without oxidation. The furnace has novel design, rational structure, energy saving, high heat efficiency, stable production quality, safe and convenient use, not generating industrial pollution.

Furnace Characteristic

① Advanced temperature control : Intelligent thermostat, silicon-controlled rectifier and schneider electrical switches ensure temperature control precision of ±1℃;

② The heating hearth (muffle) is made of imported Sweden high-temperature resistance nickel alloy (310S);

③ Heating elements: High-temp. resistance wire is used, with alumina tube frame; heating elements are arranged in an upper-lower removable to ease repair or replacing; replacing resistance wire has no impact on production;

④ Protective gas: mixture (hydrogen 75% and oxygen 25%) decomposed from liquid ammonia gets into the hearth and reachesgas protection effect; Product surface will become brightness and won’t be oxidized after heat treatment.
