从China供应商批发进口Petroleum Coke As Carbon Additive — FOB条款

Carbolic raw materials have many kinds, the production process is also different, there are wood carbon, coal carbon, coke, graphite, etc., of which there are many different categories of small species. High-quality carburizing agent generally refers to the graphitized carburizing agent, at high temperatures, the carbon atoms arranged in the graphite morphology, it is called graphitization. Carbonation itself chooses pure carbon-containing graphitized substances, reducing excessive impurities in pig iron, carbon agent selection can reduce the cost of casting. Carburizing agent is calcined from petroleum coke and is an ideal material for carbon additive. Carburizing agent as a linking agent has been widely used in different industries such as metallurgy, chemistry, machinery, electricity and so on. The choice of carburizing agent is determined by the quality requirements for the production of steel or ferroalloys and the granularity of the resulting carbon north of the city. Because of the higher carbon content of the recarburiser and its lower S / P content and its porous structure, hot metal is allowed to swallow up the carbon content faster through tiny cracks, and good recarburiser is essential for the production of high quality steel Of auxiliary additives. Ningxia Teng Yuan Environmental Protection Materials Sales and Service Co., Ltd. sales of carbonation agent for casting, cast iron, steel, castings will have a carbon demand, then carbon by the name suggests is to increase the carbon content of molten iron, for example , Commonly used in melting smelting pig iron, scrap, back to the charge, pig iron high carbon content, but the purchase price relative to scrap is higher, so increase the amount of scrap, reduce pig iron dosage, plus carbon agent, can play a certain The role of reducing casting costs.
