In 1989, the blast furnace operating rate in Japan maintained at a relatively high level as demand for the steel product market was as strong as in 1988, and the steel companies were earnestly implementing mid-term rationalization plans. The average utilization factor for blast furnaces in 1988 was 1.76 t (m ~ 3 · d) rose to 1.89t / (m ~ 3 · d). Three blast furnaces were put into operation in the latest year, namely, No. 2 BF (1650m ~ 3) Iron Junjin Plant No. 4 blast furnace (5151m ~ 3) and new
