Research on Change ofAlkali Metal of Coke at BF Hearth Radial Direction and the Affection of Coke Performance

摘要：

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 lower as coke particle size from large to small in the same position of radial hearth but the ash content is higher. The alkali metal content and ash content are all higher 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 alkali metal and ΣISO content of tuyere coke are all higher than coke and the resisting coke solution and loss capacity of isotropy coke charge is higher than anisotropy.
