摘　　要：国内焦煤等主要优质炼焦煤种十分紧缺,高硫煤资源因硫分高而在使用时受到限制。大比例配入低硫无烟煤时,通过煤种特性合理搭配高硫肥煤资源,在清洁型热回收捣固式炼焦炉中,采取加快结焦前期升温速度、中期炭化室温度保持恒温、适当延长焖炉时间的焦炉工艺,成功生产出CSR≥60%的焦炭产品,且配煤成本可大幅度降低。Domestic coking coal and other main high-quality coking coal are in short supply in China,and the use of high sulfur coal resources is restrained due to high sulfur content.When large proportion of low-sulfur anthracite is mixed,high-sulfur fat coals should be appropriately added according to the behaviors of the coal kind.For environment-friendly heat recovery stamp-charge battery,qualified coke product with CSR≥60%can be produced by accelerating heat-up rate at early coking stage,maintaining constant temperature in coking chamber at middle stage,and appropriately prolonging the soaking time.This solution can dramatically reduce the coal blending cost.
