タイトルまたは説明

Description of **5mm graphitized petroleum coke GPC

Graphitized Petroleum Coke is made from high quality petroleum coke under a temperature of 2,****3,**0°C. As a high-purity carbon material, it has characteristics of high fixed carbon content, low sulfur, low ash, low porosity etc. It can be used as carbon raiser (Recarburizer) to produce high quality steel, cast iron and alloy. It can also be used in plastic and rubber as an additive. It can be used as carbon raiser (Recarburizer) to produce high quality steel, cast iron and alloy.

Specifications of **5mm graphitized petroleum coke GPC


 

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 and reduce the quantity of pig iron, or use no scrap iron at all.
It's also can be used for brake pedal and friction material.
2.Characteristics
(1). High carbon : High purity *8.***9.5%
(2). Low sulphur : 0.*1% ~ 0.*5%. 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 *0 PPM ~ **0 PPM(0.**5%*0.*3%)
(4). High carbon recovery: **- *8%.
(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.
