    • An apparatus for manufacturing a band plate has a rolling mill that includes a pair of upper and lower work rolls that roll a slab material having edge drop portions at both ends thereof, and a pair of backup rolls that contact non-rolling side surfaces of the pair of upper and lower work rolls, respectively to prevent the work rolls from being deformed. The work roll includes a reverse taper portion where a roll diameter gradually increases towards a barrel end portion thereof corresponding to the edge drop portion. The upper and lower work rolls are configured to be shiftable individually in the axial direction thereof. The backup roll includes an escape portion whose diameter gradually decreases towards an axial end thereof so as not to contact the reverse taper portion of the work roll, within a shifting range of the work roll.
    • 一种用于制造带板的装置具有一个轧机,该轧机包括一对上下工作轧辊,其在其两端滚动具有边缘部分的板坯材料,以及一对支承辊,其与 一对上下工作辊分别用于防止工作辊变形。 工作辊包括反向锥形部分,其中辊直径朝着与边缘落下部分相对的筒端部逐渐增大。 上下工作辊被构造成在其轴向方向上单独移动。 支承辊包括在工作辊的移动范围内其直径朝着其轴向端部逐渐减小以避免与工作辊的倒锥形部分接触的退出部分。
