  • Foundry coke
    Patent number: 4294610
    Abstract: An effective amount of silicon carbide, preferably mixed with graphite, is added to the blend of coals used to make a foundry coke, the blend is thoroughly mixed, pulverized, and coked in a by-product coke oven. The resulting coke has improved physical and chemical properties allowing production of gray iron with less fuel. Gray iron castings with improved hardness control at lower cost are produced by the inoculating effect of the silicon from silicon carbide and graphite in the mixture.
