低温轧制是指在低于常规热轧温度下的轧制,国外也称中温轧制或温轧。其目的是为了大幅度降低坯料加热所消耗的燃料,减少金属烧损。把开轧温度从1000℃～1150℃降低至850℃～950℃,需要提高粗、中轧机的强度,因为低温轧制在粗、中轧机组内各道轧制压力较大,因此在选择轧机和主电机容量时要考虑这一因素,并相应增加电机功率和电耗。但由于加热炉加热温度降低,节约燃料,综合平衡后仍可节能20％左右。
Low temperature rolling refers to the rolling below the conventional hot rolling temperature, also known as warm rolling or warm rolling abroad. The purpose is to significantly reduce the fuel consumed by the billet heating to reduce metal burning. It is necessary to increase the strength of the rough and medium rolling mills since the rolling temperature is lowered from 1000 ° C to 1150 ° C to 850 ° C to 950 ° C because the rolling pressure in each of the rough and medium rolling mills is low at low temperature rolling. Therefore, And the main motor capacity to consider this factor, and a corresponding increase in motor power and power consumption. However, due to heating furnace heating temperature is reduced, saving fuel, after the balance can still be about 20% energy saving.
