一种X煤在首钢的应用研究

Study of the Application of Coal X in Cokemaking of Shougang

对X煤进行了系统的炼焦试验研究，发现在炼焦生产中配加5％～8％的X煤，不会造成硫分升高的不利影响，同时焦炭灰分下降明显，焦炭强度保持稳定。该研究扩大了炼焦煤的使用范围，同时在资源使用方面为公司焦炭灰分的降低提供支持。

The systematic coking test of coal X was carried out. It was found that the addition of 5% -8% coal X in coking production would not cause adverse effects of sulfur increase, and the ash content of coke decreased significantly, and the strength of coke remained stable. The study expanded the scope of coking coal utilization, and at the same time provided support for the reduction of coke ash in the use of resources.
