摘要： Various conventional problems produced by the reason that the coil preparatory line and the reversing cold rolling line are independent of each other are to be solved by unifying the both lines without reducing efficiency of rolling operation. A reversing rolling apparatus according to the present invention includes a first and a second coiling-uncoiling units supported by a common frame, disposed between a reversing rolling mill for cold rolling steel strips and a joining unit for joining the trailing end portion of a preceding steel strip un-coiled by a uncoiling unit to the leading end portion of a following steel strip directly or via a dummy strip, or for joining dummy strips to end portions of a steel strip so that positions of both the coiling-uncoiling units are to be switchable.
摘要翻译：通过在线圈预备线和反转冷轧线彼此独立的原因产生的各种常规问题通过在不降低轧制操作的效率的情况下统一两条线来解决。根据本发明的反转轧制装置包括：第一和第二卷取开卷单元，其被公共框架支撑，设置在用于冷轧钢带的反向轧制机和用于连接前钢的后端部分的接合单元通过开卷单元将钢带直接或经由假条带未卷绕到随后的钢带的前端部，或者将假条带连接到钢带的端部部分，使得两个卷取 - 开卷单元的位置为可切换

摘要： A box annealing furnace for annealing a metal sheet includes an oxygen removal unit for removing oxygen from the atmosphere in a box annealing furnace, with a gas circulation system for withdrawing atmosphere from the box annealing furnace during annealing, treating the gas, and for refeeding the deoxidized gas to the box annealing furnace. The box annealing furnace may also include a moisture removal unit for removing moisture from the gas. The oxygen removal unit and the moisture removal unit can reliably remove oxygen and moisture from the gas and suppress the formation, during annealing, of oxide film on a ferrous metal sheet.
摘要翻译：用于退火金属片的盒式退火炉包括用于在箱式退火炉中从大气中除去氧气的除氧单元，具有用于在退火期间从箱式退火炉中排出气体的气体循环系统，处理气体，以及用于再供给脱气气体到箱式退火炉。箱式退火炉还可以包括用于从气体中除去水分的除湿单元。除氧单元和除湿单元可以可靠地从气体中除去氧气和水分，并抑制在退火过程中在黑色金属板上形成氧化膜。
