Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests.
The characteristics: Reduce the cost of steelmaking, increase economic efficiency, improve product quality, stable performance, improve the quality of molten steel, improve product performance, reduce the amount of alloy added, reduce the cost of steel and increase economic efficiency. Silicon carbon alloy instead of ferrosilicon, silicon carbide, recarburizer, reducing the amount of oxygen scavenger, a converter for deoxidizing alloy, the effect of stability, steel chemical composition, mechanical properties and internal quality are better than the traditional process. By testing and production shows that using Si-C alloy to converter deoxy-alloy process, greatly reduce the cost of steel, creating considerable economic benefits, improve the market competitiveness of steel. The effect of using a silicon-carbon alloy species 1, can replace ferrosilicon and carburant, FeALSi dosage is also reduced, can effectively reduce the cost of steel 6-10 yuan / ton steel 2, smelting carbon steel, special steel and some low-alloy steel, the effective recovery of effective elements.
Ferro silicon is used as an essential alloy in the production of steel and cast iron. Ferro silicon is used to remove oxygen from steel and as alloying element to improve the final quality of the steel. Ferro silicon can also be the basis for manufacture of pre-alloys like magnesium ferro silicon (fesimg), used for modification of melted malleable iron. Main markets are the worldwide producers of alloyed, stainless and carbon steel. One of the fastest growing categories within steel is the stainless sector, in both flat and long products. Stainless steel has a specific consumption of ferro silicon 510 times higher than regular carbon steel. Special ferro silicon grades, like low al, high purity and low c ferro silicon, are used in the production of special steel qualities. Compared to regular ferro silicon, special grades of ferro silicon will help to keep both the content of inclusions and the carbon content in the final steel at very low levels. Ferro silicon is produced in submerged arc furnaces, using as raw material high-purity quartz, charcoal and iron ore.
