为了改善板坯的质量和减少燃料的耗量,加热炉内板坯温度测量是需要的。若板坯温度太低,它就不能正常地通过轧机,若板坯温度太高则耗费了燃料,而且其质量也可能受到轧入氧化铁皮的影响。为了避免轧机等待板坯所造成的损失,加热工力图将板坯加热得比要求的温度高。加热工依照板坯尺寸大小及在炉内的加热时
In order to improve the quality of the slab and reduce fuel consumption, furnace slab temperature measurement is needed. If the temperature of the slab is too low, it can not pass through the rolling mill normally, fuel is consumed if the temperature of the slab is too high, and its quality may also be affected by rolling into the scale. In order to avoid the rolling mill waiting for the slab caused by the loss of heating work plans slab heating higher than the required temperature. Heating in accordance with the size of the slab and the heating furnace
