Ferroalloy purposes: as a reducing agent. Silicon alloys are used as the reductant production of molybdenum iron, vanadium iron and other iron alloy; and silicon-chromium alloys, silicon manganese alloys are used as a reducing agent in the production of low-carbon ferromanganese. Other aspects of the use. In non-ferrous metallurgy and chemical industry, Cleaner, ferroalloy also becoming more widely used. Ferroalloy production methods: the main method of ferroalloy electric furnace smelting, Cleaner suppliers, its production accounts for more than 70% of the total ferroalloy production. According to the choice of the reducing agent is different, electric furnace is divided into carbon and silicon thermal calorimetry. Carbon calorimetry. Using carbon as a reducing agent in the production of ferroalloy electric furnace, often referred to as ore reduction furnace referred submerged arc furnace.
