Research on High Temperature Reaction Characteristics of Coke in Blast Furnace

The high temperature reaction characteristics of coke used in Angang 1^# BF and 2^# BF were investigated by grainy coke method, blocky coke method and organization structure method, the results of the three methods were compared, the inner influencing factors which resulting the difference between the two determination methods were analyzed and the linear relation between results of grainy coke method and blocky coke method was obtained. According to the performance analysis results of coke into BF of Angang 1^# and 2^# BF, measures were obtained to improve the high temperature reaction characteristics of coke into BF of Angang.
