Recarburizer is a carbon material using for carburization of steel and cast iron in the high temperature. Low content of Nitrogen is a significant characteristic of the material. Recarburizer is used to adjust the carbon content of the steel while it is still liquid before casting. Also, it is applied during the steelmaking with low cast iron content in charge in Siemens-Martin, oxygen converter and electro smelting processes.
There are many kinds of raw material for recarburizer including carbon, coke and graphite etc. and production process is also different. High quality recarburizer refers to carburant through graphitization, under the condition of high temperature. Graphitization can reduce the content of impurities in the carburant, sulfur content and improve the carbon content of carburant.
Recarburizer is used in casting, which can greatly increase the dosage of scrap steel and reduce the dosage of pig iron. Different kinds of cast iron, depending on need, choose different kinds of recarburizer. Pure carbon graphite material reduces too much impurity in the iron so use appropriate recarburizer can reduce the cost of castings.
High carbon, low sulfur, low nitrogen,high graphitization degree,high carbon recovery (92% ~ 98%),with stable effect on improving the carbon content.

OUR PRODUCT 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.

Graphitized Petroleum coke is mainly used for metallurgy & foundry, it can improve the carbon content in steel-melting and casting, Also it can increase the quantity of scrap steel andreduce the quantity of pig iron, or use no scrap iron at all.
It’s also can be used for brake pedal and friction material.
