  • Patent number: 6237205
    Abstract: 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.

  • Patent number: 6228321
    Abstract: 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.
