S 0.05% Green Delayed Petcoke , Calcium Petroleum Coke Low Porosity

Graphite Petroleum Coke Application

Acting as the inoculant and carburizer, it's widely used in the special steel smelting and precision casting process, especially meeting the requirement of high quality product and strict control of sulfur content in the ductile iron and grey iron casting industry. lt's also used as reducer agent in the nuclear reactor, the absorbent of heavy metal in the waste water treatment system and the raw material of graphite cathode in the aluminum electrolysis cell.

Product Advantages:

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

2. Low sulfur: 0.01-0.05% low sulfur and stable distribution could effectively reduce the adverse effect of sulfur in spheroidizing and pregnant process to the alloy and it saves the cost.

3. Low nitrogen: nitrogen content 50ppm-300ppm(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 the GPC, powder and inoculant consumption, which will save production cost.

9. Stable carburetion, good absorption rage 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.
