Graphitized petroleum coke carbon raiser / GPC/ Recarburizer/ Recarburiser/Carbon additive
Graphite petroleum coke is made from low sulfur and low nitrogen petroleum coke by graphitizing process in 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 grey iron casting industry.
Advantages:
A. High carbon content: Carbon content is higher than 99%. High purity, less 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.
