1.Using the Calcined petroleum coke can make the most of the scrap steel and reduce using the pig iron. The content of carbon is very high. Its color is black. And using Calcined petroleum coke can decrease the impurities of pig iron.
2.In the process of smelting, adding the Calcined petroleum coke into liquid steel can make carbon in the steel meet the desired requirements. The use of Calcined petroleum coke can reduce the cost of casting iron.
