Graphite Petroleum Coke
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 amou*f 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 conte*f 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 improveme*f 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 s*e the cost remarkably.
