摘要： A continuous annealing technique for a steel band. Since a deformation occurs due to the weight of coil itself at the lower end of the coil making contact with a base plate of an annealing oven for a cold rolled steel plate, the value of the product is lowered remarkably. In order to prevent this, a method is known wherein the part which will become the lower end of the coil is selectively cooled by a selective cooler (7) at a cooling step (3) after a continuous annealing step before annealing a coil box. This device contemplates to avoid the effect of the variation in the length of the side edges of the steel band due to the deformation caused by the selective cooling owing to the variation in the state of a continuous annealing oven and other factors. This device effectively reduces the deformation caused at the lower end of the coil by controlling a selective cooler (7) according to a steel band plate end detector (8), a plate temperature detector (9) or tension detector (14).
摘要翻译：钢带的连续退火技术。由于线圈本身在与冷轧钢板的退火炉的基板接触的下端发生变形，所以产品的价值显着降低。为了防止这种情况，已知一种方法，其中在退火线圈箱之后，在连续退火步骤之后，在冷却步骤（3），通过选择性冷却器（7）选择性地冷却将成为线圈下端的部分。该装置考虑到由于连续退火炉的状态的变化等因素而导致的选择性冷却引起的变形，避免了钢带的侧缘长度变化的影响。该装置通过根据钢带板端部检测器（8），板温度检测器（9）或张力检测器（14）控制选择性冷却器（7）来有效地减少在线圈下端引起的变形。
