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.

Coke is coal in isolation under the conditions of high temperature air dry distillation get of the product. Main purpose: it is widely used in iron and non-ferrous metal smelting, casting, chemical industry, calcium carbide and ferroalloy, etc.
Metallurgical coke is produced by carbonization of coals or coal blends at temperatures up to ***0 K to produce a macroporous carbon material of high strength and relatively large lump size.
Metallurgical cokes must have a high strength to support heavy loads in the blast furnace without disintegration. Metallurgical coke is also used as filler coke for polygranular carbon products.
