The electric furnace is a heating furnace that converts the electric energy in the furnace into heat to heat the workpiece. Compared with the fuel furnace, the advantages of the electric furnace are: the atmosphere in the furnace is easy to control, and it can even be evacuated; the material is heated quickly, the heating temperature is high, and the temperature is easy to control. Vacuum heat treatment of aluminum alloy die castings The electric furnace is a heating furnace that converts the electric energy in the furnace into heat to heat the workpiece. Compared with the fuel furnace, the advantages of the electric furnace are: the atmosphere in the furnace is easy to control, and it can even be evacuated; the material is heated quickly, the heating temperature is high, and the temperature is easy to control. Vacuum Oil Quenching for steel hardening heat treatment The production process is easier to realize mechanization and automation; labor hygiene conditions are good; thermal efficiency is high; product quality is good; In the metallurgical industry, electric furnaces are mainly used for smelting, heating and heat treatment of steel, ferroalloys and non-ferrous metals. Industrial-scale electric furnaces appeared at the end of the 19th century. MIM degreasing and sintering for ceramic hard alloy Since the 1950s, due to the increase in demand for advanced metallurgical products and the decline in electricity costs with the development of the power industry, the proportion of electric furnaces in metallurgical furnace equipment has increased year by year. Electric furnaces can be divided into resistance furnaces, induction furnaces, electric arc furnaces, plasma furnaces, electron beam furnaces, etc.Study on Vacuum Brazing Technology of Silver-Cu-Based Solder
