Semi-Coke instead of Metallurgical coke for coke fuel

Characteristics 

(1). High carbon : High purity 98.5-99.5%

(2). 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.

(3). Low nitrogen : nitrogen content 50 PPM ~ 300 PPM(0.005%-0.03%)

(4). High carbon recovery: 92- 98%.

(5). Fast absorption speed: it's easily dissolve in the molten iron.

(6). High graphite crystal nucleus and high graphitization degree: it can reduce the iron liquid contraction tendency and improve
the mechanical properties of casting.

(7). 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.

(8). 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.
