包钢焦炭高温冶金性能的研究

Study on the high temperature metallurgical properties of coke at Baotou Steel

在实验室对包钢焦炭高温冶金性能进行了测定,测定结果:焦炭反应性(CRI)平均为25％～28％,反应后强度(CSR)平均在60％以上。根据包钢原料条件,加入KCO_3,进行了抗碱试验,结果如下:CRI增加了10％以上,CSR下降了15％,说明碱金属对焦炭溶损催化作用明显。

The high temperature metallurgical properties of coke for Baotou Steel were determined in laboratory, the results are as follows: CRI is about 25%-28% on the average,CSR is more than 60%. Anti-alkali metal test results showed that coke CRI increased by more than 10% and CSR decreased by more than 15%.
