| Abstract: | According to the theory of carbon balance, it is shown that the cha- racteristic parameters of the grid coke in B. F are deteriorated with the increase of coal injection rate. lnvestigations into the effect of coke quality, solution loss, insititu-reduction and coke-melt reactions on the coke beat strength as well as increasing the ore preneduction degree and using new charging technic to restrain the coke degradtion are intraduced . With the above aim, the optimum of B. F operation under an ultra coal injection rate is discussed. |
