Production methods of ferroalloys

According to equipment: blast furnace method, submerged arc furnace method, electric arc furnace method, outside furnace method, vacuum resistance furnace method, oxygen converter method. According to process characteristics, it is divided into solvent-free method and solvent method.

According to heat source, it is divided into carbon heating method, electrothermal method, electrosilicothermic method, and metal heating method. Basic equipment: The mechanical equipment of the submerged arc furnace is relatively complex. In addition to the furnace, attention should be paid to including the electrode holder system, electrode press and release device, click and lift system, charging system, tapping equipment, protective equipment, electrode water cooling system, and power supply equipment.
