美国与俄罗斯瘦焦煤的煤质分析及应用

Coal Analysis and Application of the Lean Caking Coal from the US and Russia

通过对美国Buchanan矿和Windber矿以及俄罗斯K10三种瘦焦煤煤质对比分析,可知3种瘦焦煤普遍具有较强的结焦性,单独炼焦均可形成较好的焦炭组织,在保持焦炭强度基本稳定的情况下,可以替代一部分国内的焦煤。并简要介绍了沙钢焦化厂近年来配用该三种瘦焦煤的情况,使用这三种瘦焦煤,可以降低配合煤成本。

Comparative coal property analysis of the three kinds of lean caking coals from Buchanan and Windber of the US and K10 of Russia was carried out and the results showed that all the three lean caking coals have strong caking property. When they were coked separately, they could form good coke optical texture. While maintaining basically stable strength, they could replace part of the domestic caking coals. Briefed also in the paper was the blending practice of the three lean caking coals in Shasteel coking plant in the recent years. And using of these lean coals could reduce the costs of the blending coals.
