Due to the large-scale blast furnace and the uneven distribution of coking coal resources, it is necessary to meet the requirements of coke quality, and produce high quality coke by using different coal according to a certain proportion.To select the coal meeting different requirements of coking process according to the specific requirements for the production of coke quality.There are dozens of mature coking technology, conventional top coal coking technology and tamping coking technology were discussed, and issues on the impact of commonly used coking coal indicators on coke quality, requirements on coal quality of different coking process and typical coal.%由于高炉的大型化以及用于炼焦煤资源的不均衡分布,需要在能满足焦炭质量的要求下,将不同的煤按一定的比例配合使用,生产出优质的焦炭.要按对生成焦炭质量的具体要求,选择符合不同炼焦工艺要求的煤质.成熟炼焦工艺目前已有几十种,本文探讨了常规顶装煤炼焦技术和捣固炼焦技术对生产冶金焦的煤质要求,并阐述了常用炼焦用煤指标对焦炭质量的影响、不同炼焦工艺对煤质的要求和典型煤种等问题.
