Graphite Petroleum Coke(GPC)
1.Physical and chemical indicators
A. physical indicators : the main index is the size, below 0.2mm, 0.2-1mm, 1-5mm, 3-8mm, 3-10mm and so on, also can be manufactured into various size.
B. chemical index : the main chemical index effect of increased carbon agent quality with C ( carbon ), S ( sulfur ), H2O ( water ), V ( volatile ), Ash ( ash ), N ( n ), the content of carbon and sulfur content is the decisive factor.
Currently on the market by quality classification carbon agent is as follows:
Specifications | F.C.%(Min) | S% (Max) | Ash % (Max) | V.M. Max | N% Max | Moisture % (Max) |
| xx006-1 | 98.5 | 0.05 | 0.70 | 0.70 | 0.03 | 0.05 |
| xx006-2 | 99.0 | 0.03 | 0.50 | 0.50 | 0.02 | 0.03 |
| Grain Size | 0-5mm, 1-5mm, 3-8mm, or at customer's option. | |||||
| Packing | In 50kgs bags or 1000kgs big bag, or at customer's option; | |||||
2.Application:
Used to improve the carbon content in steel-melting and ductile iron foundry. Also it can increase the quantity of scrap steel and reduce the quantity of pig iron, or use no scrap iron at all.
