摘要:

建立在传统的单种煤基础上的配煤炼焦理论难以适应现代煤源状况,必须依据中国煤炭分类的原则和商品煤反射率分布图来确定炼焦煤的黏结性和结焦性,鉴别其混煤的程度,正确评价混煤的性质及其在炼焦配煤中的作用,通过小焦炉炼焦,制定合适的配煤方案。试验表明,合理利用混煤配煤炼焦,可以消除混煤对炼焦配煤的不利因素,生产出高质量的焦炭,满足高炉生产的要求。

Abstract:

The traditional coal blending coking theory could not adapt modern coal source conditions as it is established based on single type of coal.It is necessary to determine the caking and coking properties of coking coal according to Chinese classification principles of coal and reflectance distribution diagram of commercial coal,which could also identify the degree of mixed coal,correctly evaluate the property of mixed coal and its role in coking coal blending,and make appropriate coal blending scheme through coking in small coke ovens.The test shows that reasonable use of mixed coal in coal blending could reduce negative factors of mixed coal in coal blending so that coke of high quality could be produced which could meet the requirement of blast furnace production.
