实现年产90万吨生产任务对小型连轧加热炉的要求与策略

The requirement and strategy towards small-section steel rolling heating furnace for reaching the capacity of 900,000 tons per year

根据小型连轧现有加热炉生产水平,必须采用热装、煤气改质,提高轧线作业率等方法进行综合改造,使加热炉额定产量提高到145t/h,才能满足年生产90万t需求。

According to the existing production capacity of heating furnace,small-section steel rolling plant have to make comprehensive modification,i^e^adopting the methods of hot-charging heat value of coal gas,raising working rate etc.The raising rated production capacity of heating furnace was raised to 154t/h to meet the requirement of 900000 tons per year.
