用热带轧机轧制的带钢在高温状态被卷取在卷取机上,但因带钢与卷筒之间产生热传递,使最初卷取的十几圈带钢受到急冷,其金属组织与其它部分不同。这种材质的带钢必须通过下一工序的再加热,调整其内部组织,或切除部分被冷却的带铜。为了解决这一问题,日本研制成这样一种热带卷取机,即在卷简的外周内装有很多小的加热装 The strip rolled by a hot strip mill is coiled in a coiler at a high temperature. However, heat is transferred between the strip and the reels to quench a few dozen turns of the strip initially coiled, and the metal structure is coiled with other Part different. The strip of this material must be reheated in the next process to adjust its internal structure or to remove part of the copper strip that has been cooled. In order to solve this problem, Japan developed such a tropical winder, that is, it has a lot of small heating devices
