Ferroalloy smelting: reduction in the electric furnace with coke or other ores with addition of carbonaceous reducing rely on heating energy for smelting. Electrode into runtime charge, except between the electrode tip and coke particles arc, the main charge and slag resistance heat by heating. Manganese and chromium and other elements when combined with the reduction of carbon into carbide, therefore ferromanganese smelting, when ferrochrome, get the products with high carbon content. Refining molten alloy obtained at regular intervals and slag discharged from the taphole. Particularly high melting point alloy (such as tungsten iron manganese silicon calcium can not release wholesale, the method used to take iron or caking ferroalloy smelting production: BOF method main equipment used for BOF converter method, according to the way silicon oxygen calcium and manganese procurement, there are top, bottom, side, and top and bottom blown composite blowing method. raw material used is a liquid high carbon ferro alloys, pure oxygen, cooling agents and slag materials. The liquid alloy of high carbon manganese silicon calcium into the converter , hyperbaric oxygen into the furnace through the lance through blowing, relying on the oxidation reaction heat released decarbonization of high quality silicon calcium, manganese production is carried out intermittently. The main production of a variety of low-carbon ferrochrome, low carbon ferromanganese. The main equipment used method for BOF converter, oxygen their way, there are top, bottom, side, and top and bottom blown composite blowing method. raw material used is a liquid high carbon ferro alloys, pure oxygen, cooling agents and slag and other materials . The high-carbon alloy of liquid into the converter. hyperbaric oxygen into the furnace through the lance through blowing, relying on the oxidation reaction to the release of heat removal, the production is carried out intermittently. The main production of a variety of low-carbon ferrochrome, low carbon ferromanganese, etc. Buy silicon calcium and manganese, metallurgical Wing (certified), Guizhou Province manganese silicon calcium provided by Anyang Wing metallurgical Refractories Co., Ltd.
