Ferroalloy production methods: electric furnace. Ferroalloy electric furnace smelting is the main method, with its output accounting for more than 70% of the total ferroalloy production. According to the choice of different Jiangsu ferrosilicon inoculants, electric furnace reductant 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. Ferroalloys: the melting point of the different components of ferrosilicon ferrosilicon inoculant Hebei is not the same, such as 45% ferrosilicon melting point of 1260 ℃, 75% ferrosilicon was 1340 ℃. Ferromanganese manganese and iron alloy Jilin ferrosilicon inoculant, which also contains carbon, silicon, phosphorus and other small amounts of other elements, according to their carbon content is different, ferromanganese into high-carbon ferromanganese, medium carbon ferromanganese and low-carbon ferromanganese. Manganese alloy containing a sufficient amount of silicon called silicon-manganese alloys.
