2、Resistance heating annealing furnace principle

Resistance heating annealing furnaceat runtime,Thermal effect based on current. When current passes through resistive materials (such as resistance wires, resistance bands, etc.), due to the existence of resistance, electric energy will be converted into heat energy, which will make the resistive materials heat up. This heat is then transferred to the workpiece or material in the furnace to achieve the purpose of heating.。
