Ferroalloy production methods: heating method is the production of ferro-alloys (high-carbon alloy), the main method; silicon thermal power is reduced ore in an electric furnace, silicon oxide or slag (or intermediate products such as ferrosilicon or silico-manganese silicon chromium alloy) and to make lime flux production of ferroalloys. Therefore Henan calcium aluminosilicate particles, low carbon content of products obtained; for the production of high melting point, low carbon alloy or pure metal, metal thermal method should be used, metal heat thermal reduction method is to use a chemical reaction to heat alloy and slag, and the reaction automatically. Ferroalloy steel industry is an important raw material and machinery essential for the foundry industry, its main purpose: First, as a deoxidizer calcium aluminosilicate particles manufacturers, the elimination of excess oxygen in the molten steel; the second is as an alloying element additive calcium aluminosilicate particles, improve the quality and performance of steel. As China's iron and steel industry sustained and rapid development Buying calcium aluminosilicate particles of varieties of steel, continues to expand and improve the quality of products put a higher demand ferroalloy, ferroalloy industry is increasingly becoming relevant technologies and supporting engineering steel industry.
