摘要
通过研究负碱焦炭在短时间内的溶损反应程度,发现捣固焦在反应初期速率较低,但在高温呈现较高的反应性;反应后,顶装焦内部以中粒和粗粒结构为主,气孔较小,数量多,而捣固焦内部以各向异性和细粒结构为主,存在大的贯穿气孔,气孔数量少;捣固焦内存在贯穿气孔和细小裂纹,气孔不均匀度略大于顶装焦。
The solution loss degree of alkali bearing coke in a short time xs stualea. Hte LUUU,,~A$ conclusion is drawn. At the initial period the coke made with stamp-charging battery has a lower rate of reaction and higher reactivity under high temperature. After reaction, inside the coke made with top- charging battery there are mainly medium and coarse grain structures with small pores but more in quantity; while inside the coke made with stamp-charging battery, there are mainly anisotropic and fine- grain structures with bigger through pores and less in quantity; inside the coke made with stamp-charging battery, through pores and fine cracks exist and its unevenness of pores is greater than that of the coke made with top-charging battery.
