第一季平炉钢超额6.78%完成了国家计划,其中有73.50%是由于作业率提高而超产。全局第一季平炉实际作业率比计划提高3.72%,比去年第四季提高3.41%;全局第一季平炉日历利用系数是5.130,比去年第四季4.744提高了8.13%。作业率是自日历时间减去热修和冷修时间算得,兹就第一季热修和冷修工作情况分别阐述如下。

In the first quarter, 6.78% of overburden steel completed its national plan, of which 73.50% was over-produced due to the increase in operating rates. In the first quarter of 2007, the actual operating rate of hearth furnace increased 3.72% over the plan and 3.41% from the fourth quarter of last year. The utilization factor of flat hearth calendar for the first quarter of 2010 was 5.130, an increase of 8.13% over the previous year’s fourth quarter of 4.744. The operating rate is calculated by subtracting the hot fix and the cold fix time from the calendar time. The hot fix and cold repair jobs in the first quarter are respectively described as follows.
