摘  要:为了拓展兰炭应用范围,在40kg焦炉开展兰炭粉配煤炼焦及优化试验。试验结果表明:随着兰炭量的增加,配煤的黏结指数、胶质层最大厚度、奥亚膨胀度、塑性区间和最大流动度均有下降,焦炭质量变差;加入煤粉改性材料(ZBS)后炼焦,焦炭质量得到改善;ZBS的质量分数达到0.10%时焦炭质量的改善幅度最大,其M40、M10、CSR接近原配煤的炼焦指标,可以满足生产要求。The test of modifying semi-coke and blending for cokemaking were carried out in 40 kg coke oven for enlarging the application of semi-coke in coking industry.Experimental results show that: the value of caking index(G),maximum thickness of colloidal layer(y),Audibert-Arnu dilatation(b),plastic range and maximum fluidity of blended coal decrease with the increase of semi-coke.However,it would be improved significantly with the addition of ZBS modifying additive.The best improvement can be achieved when 0.10% of ZBS is mixed with the semi-coke.The quality of the resulted coke was very close to the index of the coke with original coking coal and the production requirements can be met.
