摘要
蒙古国煤储量丰富,价格低廉,黏结指数在50左右。为了合理使用蒙古国煤,降低配煤成本,利用40kg试验焦炉对其进行捣固炼焦试验研究。研究表明,蒙古国煤具有较高的反应活性,单独炼焦后焦炭反应性高,反应后强度低;在基础煤较好条件下,使用20%左右的蒙古国煤,可炼制M40≥80%、M10≤7%、CRI≤30%、CSR≥60%的焦炭。
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 af- ter 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.
