Granular Coke for Ferrosilicon Metallurgical Coke Hard Coke 20-50mm
Granular Coke is a kind of additives used in steelmaking, casting, is an essential part of raw materials, production of high quality steel electrode paste are in addition to production of raw materials. Recarburizer there are many kinds of raw materials, production process is different, have wood carbon, coal carbon, coke, graphite, etc, among them under various classification and there are a lot of small type. High quality recarburizer generally refers to after graphitization of carburant, under the condition of high temperature, carbon atoms arranged in the microstructure of graphite, so called the graphitization. Graphitization can lower the content of impurities in the carburant, improve the carbon content of carburant, reduce sulfur content; Apply to cast iron (steel) and carbon, grey iron casting high carbon, low sulfur, low water content and the characteristics of low cost and high cost performance.
