    • A rolling mill capable of forming a hot, continuously cast metallic strand into a strip with a large bite and with one pass per mill stand uses only two small diameter rolls per stand, each mounted for rotation in a pair of chock blocks and each having a comparatively narrow, enlarged diameter working portion. The outer surface of the working portion is profiled to maintain the product centered on the rolls and to accommodate for thermal expansion. An hydraulic motor that produces a large torque at a low rotational speed with good control rotates each roll. The motors are coupled to their associated rolls directly. A pair of hydraulic cylinders mounted on upper frame beams are each connected to one of the chock blocks of the upper roll. The upper frame and the cylinders pivot together to provide a direct overhead access to the rolls and their chock blocks for a rapid replacement of the rolls. The mill includes rotary brushes that are adjustably loaded against the working portions of the rolls to remove adhered strand material and to prevent a release agent from accumulating on the rolls. An entrance guide assembly provides a partial atmosphere control and edge rolls that to some extent steer the strand to the center of the rolls. A narrow strip with a recrystallised grain pattern and accurately controlled dimensions is produced by three such two high mills operating In tandem. The first mill produces the high reduction and sets the width of the strip. The second mill reduces the thickness further. The third mill is a finishing mill that produces a final thickness reduction.
    • 能够将热连续铸造的金属线材成形为具有大口径并且每通过一次轧制一次的轧制条的轧机仅使用两个小直径轧辊,每个轧辊安装成一对轴承座,并且每个具有 比较窄,直径较大的工作部分。 工作部分的外表面被成型以将产品保持在辊上的中心并适应热膨胀。 在良好控制下以低转速产生大扭矩的液压马达可旋转每个滚筒。 马达直接连接到相关的滚筒。 安装在上框架梁上的一对液压缸各自连接到上辊的一个轴承座。 上框架和气缸枢转在一起以提供对辊和它们的轴承座的直接顶部进入,以快速更换辊。 该研磨机包括旋转刷,其可调节地装载在辊的工作部分上以去除粘附的股线材料并防止脱模剂积聚在辊上。 入口导向组件提供局部气氛控制和边缘辊,其在某种程度上将该线转向辊的中心。 具有再结晶晶粒图案和精确控制尺寸的窄带由三个串联操作的两个高磨机产生。 第一台轧机产生高的压下量并且设定带材的宽度。 第二台磨机进一步降低了厚度。 第三台轧机是精轧机,最终减少了厚度。
