到本世纪末,我国钢产量要增长一倍,而能源供应只增加一半左右,另一半则靠节约来解决。轧钢加热炉能耗占轧钢工序能耗的70～75％,相当于钢铁工业总能耗的10％左右。因此抓好轧钢加热炉的节能也是关系到钢铁工业全局的大事。 炼钢供给的大钢锭在均热炉内加热,小钢锭、连铸坯以及来自轧钢厂的钢坯一般均在连续加热炉内加热,然后进轧机轧制。 By the end of this century, China’s steel production will double, while energy supply will only increase by about half, while the other half will depend on economy. Rolling furnace energy consumption accounts for 70 ~ 75% of the energy consumption of the rolling process, equivalent to about 10% of the total energy consumption of the steel industry. Therefore, a good grasp of energy-saving rolling furnace is also related to the overall event of the steel industry. Large steel ingots supplied by steelmaking are heated in a soaking furnace. Small ingots, slabs, and billets from rolling mills are generally heated in a continuous heating furnace and then rolled into a rolling mill.
