1990年日本的钢铁产品市场需要与1989年一样旺盛,各钢铁公司稳健地执行中期合理化计划,因而高炉的作业率仍维持了较高水平。高炉利用系数由1989年的1.85t/(m~3·d)上升到1.93t/(m~3·d)。一年来有6座高炉开炉,8座停炉(开、停炉变化见表1)。到1990年10月底生产的高炉为33座,比上年度同期减少了2座。高炉生产指标见表2。
Japan’s steel product market in 1990 needed to be as vigorous as in 1989, with each steel company steadily implementing its mid-term rationalization plan, and the operation rate of the blast furnace remained at a relatively high level. Blast furnace utilization factor increased from 1.85t / (m ~ 3 · d) in 1989 to 1.93t / (m ~ 3 · d). In the past year, six blast furnaces were opened and eight furnaces were shut down (see Table 1 for the change in shutdown and shutdown). By the end of October 1990, 33 blast furnaces were produced, a decrease of 2 from the same period of the previous year. Blast furnace production indicators in Table 2.
