An Investigation into Coal Blending and the Addition of Semi-coke

The grindability,explosibility and ignition point of coal and semi-coke to be injected into blast furnace has been tested to determine the appropriate blending scheme,and the effect of coal blending on coal properties has also been discussed.The results show that through coal blending,the grindability of coal is increased while the explosibility and ignition point of coal are lowered,so the mixture consisting of anthracite,bituminous coal and semi-coke can exhibit better metallurgical properties.
