We introduce to you Metallurgical grade silicon carbide the only chemical compound of carbon and silicon.It was originally produced by a high temperature electro-chemical reaction of sand and carbon. silicon carbide is a powerful fuel for steel-marking providing energy to the process. Adding silicon carbide the stell-marking can raise the temperature increase into the LD furnace; increase the usage of scrap being more cost-effective. The exothermic property of Silicon Carbide is more cost-effective when compared with Ferro Silicon; in additon Silicon Carbide has lower impurities as Sulfur and Aluminum. Silicon Carbide works as deoxidizer of the melt and also as a pure source of Silicon and Carbon in a unique material. Silicon Carbide has very low levels of Sulfur, Aluminum, Nitrogen and Hydrogen promoting higher quality compared with Ferro Silicon and other alloys. Silicon Carbide promotes also the recovery of FeO from the slag increasing the yield of the melt.
Silicon Carbide provides more energy than Ferro Silicon when equivalent silicon units are used. In comparison to coal. Silicon Carbide allows greater substitution of hot metal due to significantly lower sulfur and carbon monoxide emissions. Exothermic properties of Silicon Carbide are cost-effcetive for mills with hot metal shortages or temporary blast furnace outages. Silicon Carbide can also be used to raise tap temperatures. Silicon Carbide grain is an effective slag deoxidizer, as well as an excellent source of silicon and carbon. It's low aluminum, sulfur and nitrogen content make it a very cost effective material to replace Ferro Silicon or Silicon Manganese.
There are many advantages to using Silicon Carbide in steelmaking:
1. Raising the temperature in the LD furnace.
2. Increasing the use of scrap, which is more cost-effcetive.
3. Lower impurities such as Sulfur and Aluminum.
