Abstract：The coke of whole hearth radius BF is got by sampling machine of tuyere coke. The change of alkali metal content of coke in the different position of radial hearth and different particle size are analyzed. The conclusions are that the alkali metal content is higher as coke particle size from small to large in the same position of radial hearth and also as position from BF wall to center in the same tuyere coke particle size. The alkali content of hearth coke and coke charge through optical organization method are analyzed as well. The conclusions are that the resisting coke solution and loss capacity of isotropy coke charge is higher than anisotropy and the isotropy tuyere coke ratio of QIANAN NO.1 BF has no relation with alkali metal content.
