ferro silicon calcium manufacturers

Ferro silicon calcium manufacturers always produce the silicon calcium with reducing silicon dioxide (silica) and calcium oxide (lime) at the same time with a carbonaceous reducing agent (coke) in a submerged arc furnace. The submerged arc furnace used for its production is basically the same as the furnace used for ferrosilicon production regardless of its shape or furnace parameters. Its production methods include two-step method, mixed feeding method, layered feeding method and silicothermal method.
Industrial silicon-calcium alloy is an alloy mainly composed of silicon and calcium and a small amount of iron, aluminum and other elements. Its melting temperature is quite low, generally only 980-1200 ° C. Therefore, in the normal furnace process, the flow of the alloy Sex is good.
Ferro silicon calcium manufactures supplied a particle size of 10-100mm to the steelmaking industry, it can be used as a deoxidizer, desulfurizer and warming agent. Silicon and calcium in silicon-calcium alloy have a great affinity for oxygen, and calcium has a great affinity for sulfur, and deoxidation and desulfurization products are easy to float up and get rid of, improving the performance of steel, improving the plasticity and impact toughness of steel, so silicon-calcium alloy is It is an ideal compound deoxidizer with deoxidation and desulfurization ability in steel. At present, silicon-calcium alloy can replace aluminum for final deoxidation, and is widely used in the production of high-quality steel. However, silicon-calcium alloy is more expensive, and it is easier to burn out, because it is generally only used for final deoxidation, and attention should be paid to the method of use. 
Generally, Calcium silicon can be used as deoxidizer, desulfurizer and inoculant in casting. Calcium silicon alloy can improve the performance of cast iron more effectively than ferrosilicon. In actual use, in order to play the role of calcium calcium alloy more effectively, the alloy’s The particle size should be about 2mm, and it should be directly added to the flow iron trough, iron mixing furnace or ladle.
