使用卷取箱主要用来减少带钢热轧机中驱动的电、能的消耗及降低轧制力。轧制力小可使带卷在较少的精轧机架上,在均匀温度和速度下完成轧制,并改进厚度和温度的控制。随着无卷筒传送机的侧面热挡板的研制,改善了坯料温度的一致性。同时使用了板卷蓄热炉,提高了开卷箱带钢 The use of a winding box is mainly used to reduce the electricity consumed in the hot strip mill, energy consumption and reduce the rolling force. The low rolling force allows the coil to be rolled on less finishing stands, rolling at a uniform temperature and speed, and improving thickness and temperature control. With the development of a side baffleless roll conveyor, the consistency of billet temperature has been improved. At the same time the use of the coil reheating furnace, improved uncoiler box strip
