Ferrochrome is the most important raw material for the production of stainless steel, mainly used in the production of stainless steel, ball bearing steel, tool steel, nitriding steel, heat-strengthened steel, tempered steel, carburized steel and hydrogen-resistant steel, this is due to the chromium in stainless steel plays a decisive role in determining the stainless steel attributes of the element is only one, which is chromium, each stainless steel must contain a certain amount of chromium. Low microcarbon ferrochrome is mainly used in the production of stainless steel, acid-resistant steel and heat-resistant steel. Smelting methods include electro-silicon heat method and hot blending method. Low microcarbon ferrochrome alloy production enterprises conventional electric silicon heat method, the use of electric arc furnace, plus ferrochrome fine powder ore, lime, silicon chrome alloy and other raw materials, through the melting and refining, to get the chromium content of microcarbon ferrochrome in about 60%.
