What is a Casting resistance heating furnace? Introduction to the principle of Trolley resistance furnace structure

Casting resistance heating furnaceis an industrial furnace that uses electric current to generate heat energy through resistive materials, thus heating workpieces or materials.，the advantage is The temperature uniformity is good, and the temperature distribution in the Casting resistance heating furnace is relatively uniform, which is helpful to reduce the temperature gradient in the heating process of the workpiece and improve the heating quality.、The electrothermal conversion efficiency is high, and the Casting resistance heating furnace can efficiently convert electric energy into heat energy, which is higher than the thermal efficiency of the traditional flame furnace.、High thermal efficiency, higher than traditional heating equipment such as flame furnace.、The maintenance cost is low, the Casting resistance heating furnace structure is relatively simple, the maintenance is relatively convenient, and the failure rate is relatively low, which is helpful to reduce the maintenance cost.、Environmental protection, energy saving, no pollutants generated by fuel combustion, in line with environmental protection requirements; At the same time, due to high thermal efficiency, energy consumption is relatively low.，multifunctional, with functions such as heat treatment, Casting heating, Forging heating, hardening and tempering and heat treatment，the product looks atmospheric.，at work,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.。
