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.
