摘要:

使用俄罗斯低硫肥煤代替国内高硫肥煤,配合山西的高硫焦煤,取得了较好的配煤炼焦效果,焦炭质量稳定,同时降低了配煤成本。通过40 kg小焦炉试验、灰成分分析、显微分析等,对俄罗斯低硫肥煤的性质及应用进行了分析。当俄罗斯肥煤挥发分超过33%后,俄罗斯肥煤配比小于5%时,对焦炭冷、热强度没有明显影响;配比超出7%时,焦炭热强度明显变差。

关键词: 低硫肥煤, 配煤, 挥发分, 焦炭强度

Abstract:

This paper shows a successful case that low-sulfur fat coal from Russia instead of domestic high-sulfur fat coal,blended with high-sulfur prime coking coal achieved satisfactory result of coal blending,with stable coke quality and lower cost in coal blending.Through 40 kg pilot oven test,ash composition analysis and microscopic analysis etc.,the properties and application of the low-sulfur fat coal from Russia were analyzed.When the volatile ratio in the fat coal from Russia exceeds 33%,and the blending ratio of that is less than 5%,there would be no obvious influence on mechanical strength and CRI/CSR;when the blending ratio of the fat coal exceeds 7%,CSR deteriorated significantly.

Key words: Low-sulfur fat coal, Coal blending, Volatile matter, Coke strength ,
