Graphite Petroleum Coke

Description

Graphite Petroleum Coke is widely used as carburant in the steel-making industry and precision casting industry, reduction pregnant agent in the casting industry, reducing agent in metallurgical industry and as one kind of refractory, etc.

Graphite Petroleum Coke could promote the nucleation of the graphite in liquid iron, increase the amount of spheroidal graphite, and improve the structure and the grade of grey iron.

Characteristics：

• High carbon : High purity 98.5-99.5%
• Low sulphur : 0.01% ~ 0.05%. Low sulphur and stable distribution can effectively reduce the adverse effect of sulphur in spheroidizing and pregnant process to the alloy, and it saves the cost.
• Low nitrogen : nitrogen content 50 PPM ~ 300 PPM(0.005%-0.03%)
• High carbon recovery: 92- 98%
• Fast absorption speed: it's easily dissolve in the molten iron
• High graphite crystal nucleus and high graphitization degree: it can reduce the iron liquid contraction tendency and improve the mechanical properties of casting
• 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.
• 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
