安徽快三开奖 www.rujbz.com Calcium Silicon（Ferro Silicon calcium/silicon calcium） is used to control the shape, size and distribution of oxide and sulfide inclusions improving fluidity, machinability, ductility, and impact properties of final product.
HistoryThe calcium silicon alloy is made up of elements silicon, calcium, and iron compound alloys, is an ideal compound deoxidizer, desulfurization agent. Starting around 1907, the calcium silicon alloy was produced by silicon thermal method. At present calcium alloy can be used instead of aluminum for final deoxidation, is applied to high-quality steel, special steel and special alloys production., Such as rail and low carbon steel, stainless steel, steel and nickel base alloy, titanium alloy and other special alloy, are available the calcium silicon alloy as deoxidizer. The calcium silicon alloy by calcium, silicon and impurity content is different, divided into three grades, its chemical composition in accordance with the provisions of the table below.Application1.Calcium Silicon is used to control the shape, size and distribution of oxide and sulfide inclusions improving fluidity, machinability, ductility, and impact properties of final product.2.The most widely used method is processed into cored wire then feeding into the ladle.Size：0-2mm & 10-50mm & 20-50mm & 10-100mmPacking:1mt in one big bag, 25mt in one 20’ container
