High-efficiency graphite recarburizer produced by Foshan Yoshida Foundry Materials Co., Ltd. has high carbon content, low sulfur content, bright color, light specific gravity, uniform particle size and uniformity, small ash content, and can be added at the bottom of the furnace or added with the charge. Easy to melt and easy to absorb, and does not produce floating impurities, the unit cost of carbon is lower. Applicable to large, medium and small cupolas and electric furnaces, widely used in scrap iron making, ductile iron casting, steel making and other industries. The particle size of Foshan Jitian graphitized recarburizer is 1-5mm, 8-30mm, sulfur 0.05;

For this calcined petroleum coke, the size is 0-50mm, fixed carbon is 97%, the other specifications you can check the table above, we did test every day to inspect the quality, and we can supply 20000-30000mt/month, mainly supply to aluminium plant.

Calcined petroleum coke is a high purity carbon material produced by heating green petroleum coke to drive off moisture, volatile matter, and impurities and to increase its electrical conductivity, which is used to improve the carbon content in steel-making and ductile iron foundry. It is widely used to produce graphite electrode, graphite blocks, brakes pads and other carbon products. it can also be used as carbon additive in some steel and aluminum plants, another, it is used in refractory, insulation, filler,etc. We can supply different grades of Calcined Petroleum coke.

The main application of Calcined Petroleum coke is in the production of anodes for the Aluminum Smelting process. 70 - 80% of CPC is for the Aluminum Industry. The reason for use in the Aluminum Industry is for conductivity.

Another used for Calcined Petroleum coke is TiO2 production which accounts for about 15% of the Calcined Petroleum coke consumption. The reason for use in TiO2 is for its oxidizing effect.

Graphitized Petroleum Coke 0-3mm Recarburizer

Date: July 17, 2018

Moisture: 0.10%

Ash: 0.78%

Volatile Matter: 0.73%

Fixed Carbon: 98.39%

Sulphur: 0.18%

Nitrogen: 0.03%

Graphitized Petroleum Coke(GPC) is made from high quality petroleum coke under a temperature of 2,500-3,500°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.
