An electric resistance furnace is an industrial furnace that uses electric current to heat heating elements or a heating medium inside the furnace, thereby heating workpieces or materials. It is a heating furnace that utilizes the heat generated by the passage of electric current through a resistive material.
In the machinery industry, electric resistance furnaces are used for heating metals before forging, heating metals during heat treatment, brazing, powder metallurgy sintering, glass and ceramic calcination and annealing, melting low-melting-point metals, and drying sand molds and paint films, among other applications.
