Graphite petroleum coke carbon raiser is made from low sulfur and low nitrogen petroleum coke by graphitizing process in an advanced automotive production line with independent intellectual property rights. As a high purity carbon material, GPC is widely used in the special steel smelting and precision casting process, especially meeting the requirement of high-quality product and strict control of sulfur content in the ductile iron and gray iron casting industry.
Advantages:
A. High carbon content: Carbon content is higher than 99%. High purity, fewer impurities, certified by ISO9001, SGS or CCIC quality authorization.
B. Low Sulfur: sulfur content of 0.01% ~ 0.05%. Low sulfur and stable distribution can effectively reduce the adverse effect of sulfur in spheroidizing and pregnant process to the alloy, and save the cost.
C. Low nitrogen: Nitrogen content of 50 PPM ~ 300 PPM
D: High absorptivity rate: The absorption rate can be as high as 95%.
E. High absorption speed: Comparing with the same type of graphitized carburizer, the absorption speed of our product is much faster.
F. Cost-effective: Comparing with the same type of graphitized carburizer, our product has the higher quality and lower price. We could help you save cost and improve the quality of end-products.
G. High graphite crystal nucleus and high graphitization degree: It can reduce the iron liquid contraction tendency and improve the mechanical properties of casting.
H. It may increase the dosage of scrap steel and reduce the demand of pig-iron or even without adding pig iron. It may well effectively avoid the heredity of pig iron to affect the casting.
I. Stable carburetion, good absorption rate and distinct temperature-lifting effect. There is no return slag. It can effectively protect and lengthen the furnace life and reduce the consumption of the furnace lining.
