湘钢焦化炼焦用煤质量评价

Quality Evaluation of Coking Coal in XISC Coking Plant

湘钢焦化厂炼焦用煤矿点多,分布范围广,结焦性能好的煤种占比较少,主打煤种混煤现象严重,引起焦炭质量波动,难以进一步提升质量。本文拟对2013年焦化厂来煤质量进行简要综合评价,更好的了解其质量性能指标,在生产中合理搭配使用,达到稳定和改善焦炭质量的目的。

Coking coal of XSCI Coking Plant were purchased from many coal mines across China, while only few of them are of good coal coking properties, and mixed coal were used commonly.All these caused the instability of coke quality and difficulty of improvement.The quality of coal used in XISC Coking Plant in 2013 was briefly evaluated, thus achieving a better understanding of coal’s performance.This evaluation would benefit reasonable use of all kinds of coal in production, to finally realize the purpose of stabilize and improve coke quality.
