Furnace introduction 

Smelting melting furnace, is also known as electric arc furnace or resistance furnace, it 

is mainly used for the reduction of smelting ores, carbon reductants and solvents etc. 

It is mainly for production of ferrosilicon, ferromanganese,ferrochromium, tungsten 

iron, silicon and manganese alloy and other ferroalloy , all above are important industrial 

raw materials and calcium carbide and other chemical raw materials in metallurgical 

industry. 

Product Introduction  

Submerged arc furnace is also known as electric arc furnace or resistance electric furnace . 

It is mainly used to reduce smelting ore, carbonaceous reducing agent and solvent etc. 

Mainly adapt to production of ferromanganese , ferrochrome, silicon manganese alloy and 

other ferrous alloy.
