Heating principle of electric furnace for foundry

Heating principle of electric furnace for foundry The electromagnetic induction heating intermediate frequency melting furnace currently popular in electric furnaces for foundry can heat and melt scrap metal materials such as iron and steel, aluminum, copper, gold, silver, etc., add alloy components, and pass through slag removal and other processes to become qualified metal liquids and cast to form castings. It has the characteristics of quick start, high heating efficiency, electromagnetic stirring, instant use and low energy environmental protection. It is the preferred heating equipment for electric furnaces in the foundry industry.Requirements for deep carburizing on heat treatment equipment Heating principle of electric furnace for foundry:This electric furnace for handcuffs is a non-vacuum metal heating and smelting equipment, without gas break protection components, adding scrap metal into the casting furnace, at this time, the intermediate frequency power supply and the smelting furnace money ring are combined to generate a magnetic field in the coil, so as to create a magnetic field inside the technology. The eddy current generates self-heating, and the electric casting furnace will complete the process of heating and heat preservation according to the given temperature curve, and then transport all the metal liquid out of the furnace, and pour it into the mold to become a casting after cooling.Common Failure and Maintenance of Vacuum Quenching Furnace The composition of the electric furnace for casting: the melting system of the electric furnace for casting generally consists of a transformer, a low-voltage cabinet, an intermediate frequency power supply, a steel shell furnace body, a hydraulic tilting furnace system, a leakage furnace protection system, a cooling circulation system, a magnetic yoke, a capacitor bank, a water-cooled cable and feeding materials. car etc.Heat treatment process of gear vacuum carburizing and quenching
