Explanation

melting or heating insulation equipment heating by electric heating body. In the metallurgical and mechanical industries, resistance furnaces are mainly used for soaking or heating before metal rolling, heating before metal forging and pressing, metal heat treatment heating, soldering, powder metallurgy sintering, glass-ceramics baking and annealing, low melting point metal melting, sand mold and paint film drying, etc. It can be divided into periodic operation furnaces and continuous operation furnaces. Periodic operation furnaces include box type furnaces, well type furnaces, bell type furnaces (bell type furnaces), trolley type furnaces, tilting drum type furnaces, etc. Continuous operation furnaces include kiln car type furnaces, push rod type furnaces, roller bottom furnaces, vibrating bottom furnaces, rotary bottom furnaces, walking beam furnaces, traction type furnaces, continuous drum type furnaces, conveyor belt type furnaces, etc.
