Abstract

The coal injection rate was increased from 80 to 150 kg/thm at Kokura No. 2 blast furnace. The stable furnace condition was attained through improvement of coke strength, repair of upper shaft profile and optimization of ore layer thickness, although breakage of tuyeres was occurred due to formation of solidified layer in the hearth in the beginning of rating-up of coal injection rate.
