Advantages and Types of Industrial Electric Induction Furnace

Author : Hongteng Time: 2021-12-22

An electric induction furnace is a heating furnace that converts the electric energy in the furnace into heat to heat workpieces. Compared with fuel furnaces, the electric furnace has the following advantages: the atmosphere in the industrial furnace is easy to control and even can 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 working hygiene conditions; High thermal efficiency; Good product quality; And being more environmentally friendly is good product for increasingly serious environmental problems. Electric furnaces in the metallurgical industry are mainly used for iron smelting, steel melting, metal heating, and heat treatment of metal, ferroalloy, non-ferrous metals, etc.

Industrial-scale electric furnaces appeared at the end of the 19th century. Since the 1950s, due to the increase in demand for advanced metallurgical products and the decrease in electricity charges with the development of the electric 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, etc. Common induction furnaces are further divided into steel furnaces, aluminum furnaces, copper furnaces, and stainless steel melting furnaces.
