How Is Silicon Manganese Made?
Silicon manganese, or silicon manganese alloys, can be made by submerged arc furnace (silicon manganese furnace). They are alloys composed of manganese, silicon, iron and small amount of carbon and other elements, which used as compound deoxidizer for steel-making, and a...Read more -
How Do You Make Ferro Silicon?
Ferro silicon is made of coke, steel chips, quartz (or silica) by ferro silicon furnace smelting. In traditional ferrosilicon smelting, silicon is reduced from silica containing SiO2. Metallurgical coke is mostly used as reductant in ferrosilicon smelting, and steel scra...Read more -
