摘要:

以大比例配入无烟煤进行配煤炼焦为基础,利用40kg试验焦炉进行配煤炼焦生产高反应后强度焦炭的试验研究。结果表明,无烟煤配入量在30%~40%、焦煤和肥煤比例在50%~55%时,采用捣固炼焦工艺可以生产出CSR大于60%的焦炭,焦炭机械强度和反应后强度均达到一级冶金焦标准。

Abstract:

On the basis of blending more anthracite for coke making,a 40kg pilot coke oven is used to study the optimum coal blending ratio to produce coke with high CSR.The result shows that with 30%~40% anthracite and 50%~55% coking coal and fat coal blended,the stamp-charging coke oven can produce coke with CSR higher than 60%,and both the mechanical strength and CSR of coke meet the requirement of first class metallurgical coke.
