Description

[0002] The resistance furnace is an industrial furnace that uses electric current to heat the electric heating elements or heating medium in the furnace, thereby heating the workpiece or material. It is often used for heating metal before forging, heating metal heat treatment, brazing, powder metallurgy sintering, glass ceramic baking and annealing, melting low melting point metals, drying sand molds and paint film layers, etc. The resistance belt is one of the important components of the resistance furnace;
