Graphitized Petroleum Coke Carburizer

In traditional smelting, a large proportion of pig iron is often added. Compared with high scrap steel with the same composition, its


mechanical properties are half a grade lower. At the same time, there are many coarse eutectic graphite in pig iron, and graphitized

 petroleum coke increases carbon. The agent is hereditary, the smelting temperature is low, and the coarse graphite should not be 

eliminated. The coarse graphite is inherited from the liquid state to the solid cast iron structure. On the one hand, it reduces the


strength that the cast iron can achieve and reduces the performance of the material. The expansion effect of the graphitized


precipitation that should have been produced is weakened, which increases the shrinkage tendency of the molten iron during



Products Describe

There are many kinds of raw materials for carburizers, and the production processes are also different, including woody carbon, coal carbon, coke, graphite, etc., among which there are many small types under various classifications. High-quality recarburizers generally refer to graphitized recarburizers. Under high-temperature conditions, the arrangement of carbon atoms is in the microscopic form of graphite, so it is called graphitization.

Graphitization can reduce the content of impurities in the recarburizer, increase the carbon content of the recarburizer, and reduce the sulfur content. The carburizer is used in casting, which can greatly increase the amount of scrap steel and reduce or eliminate the amount of pig iron.

In the feeding method of electric furnace smelting, the recarburizer should be put in together with scrap steel and other furnace materials, and small doses can be added to the surface of molten iron. However, it is necessary to avoid feeding a large amount of materials into the molten iron to prevent excessive oxidation, resulting in insignificant carburization effects and insufficient carbon content in castings. The amount of fuel added is determined according to the ratio and carbon content of other raw materials.

For different types of cast iron, choose different types of recarburizers according to your needs. The characteristics of the carburizer itself select pure carbon-containing graphitized substances to reduce excessive impurities in pig iron, and the appropriate choice of carburizer can reduce the production cost of castings.
