Abstract:

Mongolia is rich in coal reserves, coal price is low and the caking index is about 50. In order to use the coal from Mongolia and reduce the cost of coal blending, the coal is used to carry out test and study for stamp-charging cokemaking with 40kg test coke oven. The study shows that the coal has high reactivity and the coke produced by separate cokemaking has a high reactivity and low strength after reaction. Under the condition of the good basic coal, the coke with M40≥80%, M10≤7%, CRI≤30% and CSR≥60% can be made with about 20% of the coal from Mongolia.
