Semi-graphite Petroleum Coke(SGPC)
Semi GPC is from the insulation layer of acheson furnace. The graphitization temperature is in the range of 1700-2500 C.It belongs to the medium temperature graphitization product. It is economical recarburizer with high fixed carbon, lower sulphur content, fast dissolution rate and high absorption rate.
High-purity graphitized petroleum coke(GPC) is made from high quality petroleum coke under a temperature of 2,500-3,500C. 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.

G-high graphite petroleum coke is widely used as carburant in the steel-making industry and precision casting industry, reduction pregnant agent in the casting industry, reducing agent in metallurgical industry and as one kind of refractories, etc.
G-high graphite petroleum coke could promote the nucleation of the graphite in liquid iron, increase the amount of spheroidal graphite, and improve the structure and the grade of grey iron.
Based on the microstructure observation, the features of g-high graphite petroleum coke are as the following:
First, it can greatly increase the proportion of ferrite content of the nodular cast iron without pearlite stabilizer; second, it can increase the percentage of v and vi shaped graphite when it is used; third, comparing with the improvement of the shape of spheroidal graphite, the great increase of spheroidal graphite amount can decrease the usage of expensive nucleating agent for later micro-adjustment and save the cost remarkably.

High-purity graphitized petroleum coke 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.
The size varies such as 0.5-5mm,0.3-5mm,0.5-8mm,0-10mm,1-4mm,5-10mm,0.4-4mm etc
Different sizes can be produced according to customers' requirement.
It is made from low sulfur and low nitrogen petroleum coke by 2500-3500
temperature graphite annealing. As a high-purity carbon material, it has characteristics
of high fixed carbon content, low sulfur, low ash, low resitance etc. It can be used as
carbon raiser to produce high quality steel, cast iron and alloy.
Carbon raiser is a carbon material, produced at high temperatures and used for carburization of steel and cast iron.
It is applied during the steelmaking with low cast iron content (allow of steel and carbon) in charge in oxygen converter and electrosmelting processes. In metallurgy carbon raiser (milled graphite) is widely used for slag foaming, during coal graphite production, as a filler for graphite-reinforced plastic.
