    • A press apparatus for reducing widths of hot slabs comprises a pair of anvils movable toward and away from each other in width directions of the hot slabs, width reduction heads to which the pair of anvils are attached, respectively, and eccentric presses for reciprocatively driving the width reduction heads through sliders, respectively. The apparatus further comprises width adjusting means incorporated in the eccentric presses, respectively, for changing distances between the width reduction heads and the sliders. Each of the anvils has a parallel portion in parallel to a feeding direction of the hot slabs and an inclined portion on an entry side in the feeding direction. With this arrangement, the reducing distance can be set according to the desired distance of reduction in width in continuous width reduction and the reduction in width can be continuously effected with the set reducing distance with high efficiency. The press apparatus preferably further comprises buckling preventing means such as rollers controlled by hydraulic cylinders for urging at least two locations of the slab along a central longitudinal line of the slab and on upstream and downstream sides of a line connecting junctions of the parallel portions and the inclined portions of the anvils, thereby preventing any buckling of the slab occurring in reduction in width of the slab.

    • PURPOSE:To decrease fishtails without promoting the width reduction in leading and tail end parts by press-forming the part apart by more than a specific distance from the end face to narrow width then applying broadside screw down and thickness screw down in the end parts in the longitudinal direction of a slab. CONSTITUTION:A pair of press heads 1 for broadside screw down moved forward and backward in the width direction by means of oil hydraulic cylinders 2 are provided to the front stage of rolling mills. The part apart by a distance (l) from the end face E of a slab S is press-formed to narrow width by the heads. However, the end part S1 is not subjected to edging. Namely, the distance (l) is at least the distance at which at least said end part S1 can retain the original shape. Then, the end part E forms the shape wherein the central part in the width direction overhangs. Next, when such slab S is rolled with rolling mills of the rear stages, the end part S1 forms a fishtail, but it is decreased considerably as it is offset by the overhanging effect of the central part in the width direction. Since the end part S1 is not press-formed, the width reduction hardly occurs.
    • 目的:为了减少鱼尾,不会通过将零件从端面与狭窄的宽度分开一段距离,将前端和后端部分的宽度减小,从而将前端和后端部分的宽度缩小, 板的纵向。 构成:用于通过油压缸2在宽度方向上向前和向后移动的用于宽侧螺旋式的一对压头1设置到轧机的前级。 与板坯S的端面E分开一段距离(l)的部分被压头成形,以使其宽度变窄。 然而,端部S1不进行边缘化。 即,距离(l)至少为至少所述端部S1能够保持原始形状的距离。 然后,端部E形成宽度方向上的中心部分突出的形状。 接下来,当这种板坯S用后级的轧机轧制时,端部S1形成鱼尾,但是随着中心部分在宽度方向上的突出效应的抵消而使其大大减小。 由于端部S1没有被压制成形,因此几乎不发生宽度减小。

    • A method and apparatus for reducing crop losses during slab and ingot rolling concerns the formation of a slab ingot having a specially configured or shaped butt end and optionally a head end as well. A special shape is formed by machining, forging or preferably by casting. The special shape at the butt end is imparted during casting by a specially shaped bottom block or starter block. The special shape of the bottom block is imparted to the cast ingot butt end. The specially shaped butt end of a slab shaped ingot is generally rectangular in shape and has longitudinally outwardly extending, enlarged portions (24), which slope downwardly toward a depressed central valley region (26). The lateral sides of the enlarged end portions and the depressed valley region carry transversely extending, tapered or curved edges. A similar shape may be imparted to the head end of the ingot at the conclusion of a casting run through the use of a specially shaped hot top mold or by way of machining or forging the cast head end. During subsequent hot rolling in a reversing roughing mill, the specially shaped slab ingot minimizes the formation of overlap and tongue so as to improve material recovery by reducing end crop losses and to increase rolling mill efficiency by increasing metal throughput in the mill.
    • 用于在板坯和锭轧制期间减少作物损失的方法和装置涉及形成具有特殊构造或成形的对接端以及任选的头端的板坯锭。 通过加工,锻造或优选通过铸造形成特殊形状。 在特殊形状的底部块或启动块铸造期间,在对接端的特殊形状被赋予。 将底部块的特殊形状赋予铸锭对接端。 板状铸锭的特殊形状的对接端通常为矩形形状,并且具有向下延伸朝向凹陷的中心谷区域(26)的纵向向外延伸的扩大部分(24)。 扩大的端部和凹陷的谷区域的横向侧面具有横向延伸的,锥形的或弯曲的边缘。 通过使用特殊形状的热顶模具或通过加工或锻造铸造头端部,在铸造过程结束时,可以向锭的头端施加类似的形状。 在倒车粗轧机的后续热轧过程中,特殊形状的板坯最小化了重叠和舌头的形成,从而通过减少作物损失来提高材料回收率,并通过提高轧机的金属产量来提高轧机的效率。
