捣固焦炭内在质量及等反应后强度指标

Stamping Coke Quality and Coke Strength After Uniformreaction Index

为了研究捣固焦炭对大高炉的适应性,在1050～1200℃使用焦炭连续热反应装置对A类顶装焦、B类捣固焦、C类捣固焦3类焦炭进行等温等反应的溶损反应.当焦炭的失重率分别达到30％,35％,40％时,停止反应,通过Ⅰ型转鼓检测焦炭的反应后强度.结果表明：捣固处理在一定程度上可以改善焦炭的热态性质;在1100～1 150℃时焦炭强度破坏程度最严重;等反应后强度与国家标准CSR存在差异性.

In order to study the stamping coke on the adaptability for large capacity blast furnace, three kinds of coke, such as A coke, B tamping coke and C tamping coke, were used for solution loss reaction experiment at 1050- 1200 ℃, and the test was stopped at a weight loss of 30% , 35% and 40%, and the strength of coke was tested by I type drum. The results show that the hot properties of coke can be improved to a certain extent through tamping treatment. The coke strength will get the worst at 1100-1 150℃. And there are some difference between coke strength after uniform reaction and standard CSR.
