Calcined anthracite carburetant has follwing advantages:
(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). Cost-effective: reduce GPC, power and Inoculant consumption, which will save production cost
(9). 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.
