Hot air Trolley Furnace


Introduction :

Heat treatment equipment provides annealing, tempering, quenching, carburizing, nitriding, heating to the workpieces.Heat treatment furnace is common name of various kinds of industrial furnace which provide metal heating treatment to all kinds of metal workpieces. It has lower temperature compared with heating furnace. Heat treatment furnace can be adopted with all models of heating furnaces but asks more stringent temperature control and furnace atmosphere.


Application :

 It is mainly used for high chromium, high manganese steel castings, ductile iron, roll, steel, stainless steel quenching, annealing, aging and a variety of mechanical parts heat treatment.  Welding parts to eliminate stress annealing, aging and other heat treatment process. Heating methods are electric heating, fuel, gas, coal, hot air circulation and etc.
