Introduction to electric furnace knowledge
Electric furnace is a heating furnace that converts the electric energy in the furnace into heat to heat the workpiece. Compared with fuel furnaces, the advantages of electric furnaces are: the atmosphere in the furnace is easy to control, and can even be vacuumed; the material is heated quickly, the heating temperature is high, and the temperature is easy to control ; The production process is easier to realize mechanization and automation; good labor and hygiene conditions; high thermal efficiency; good product quality. Electric furnaces in the metallurgical industry are mainly used for smelting, heating and heat treatment of iron and steel, ferroalloys, and non-ferrous metals. Industrial-scale electric furnaces appeared at the end of the 19th century. Since the 1950s, the demand for metallurgical products has increased rapidly, and electricity costs have decreased with the development of the power industry. The proportion of electric furnaces in metallurgical furnace equipme...
