冶金焦的本质特性与现代高炉冶炼的对应关系

 在对鞍钢焦炭质量现状进行科学分析的基础上，研究了焦炭强度、热态性能、化学组成、粒度及质量波动等对高炉冶炼的影响规律，并通过对高炉风口焦炭的实际取样与研究加以验证，指导高炉操作实践；同时，系统地掌握焦炭质量、焦炭质量对高炉冶炼的影响、焦炭质量的评价方法等；尤其是利用“风口取样”，掌握焦炭在炉内的变化规律和炉缸工作状况，为高炉操作提供技术支持，同时为焦化厂低成本生产出符合高炉运行要求的焦炭提供了依据。

Relationship between essential characteristic of metallurgical coke and modern blast furnace smelting

On the basis of scientific analysis for the current quality of Ansteel coke,the influences of coke strength, thermal state performance,chemical composition,particle size and quality fluctuation on blast furnace smelting were studied. Through sampling the coke in the blast furnace tuyere and further validation with experiment,the blast furnace operation practice could be guided well,at the same time good results were achieved. The study made the blast furnace operator and coking plant personnel in Ansteel access to knowledge related to coke quality,the influence of coke quality on blast furnace smelting,and the coke quality evaluation methods and so on,especially the use of"tuyere sampling"for which it needs to know the change rule of coke in the furnace hearth working condition. The study provides a power-ful technical support for the blast furnace operation,at the same time provides the basis for coking plant about how to implement low cost to meet the requirements of the blast furnace operation coke.
