[0002] A melting furnace for metal processing is a device used to melt metal ingots and scrap metals, add necessary alloy components, and melt them into the required alloy through a series of operations (such as slagging, refining, etc.). The basic working principle of a melting furnace is to use heat energy to heat the metal above the melting point to make it melt. An electrically heated melting furnace mainly includes a furnace body, a resistance heater, and a control system. The resistance heater is controlled to heat the metal material in the furnace body until the metal reaches the melting point and melts into a liquid state.
