specification parameter

(1). High carbon :

High purity 98-99%

(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). The absorption rate of carbon is high

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 iron liquid contraction

 tendency and improve the mechanical properties of casting.

It increase 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.

Cost-effective:

reduce GPC, power and nucleating agent, which will save production cost

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.
