摘要： PURPOSE: To provide roller method and equipment of rolling mills for sheets or plates capable of improving an edge drop vastly, reducing its variance and continuing rolling operation efficiently, without forming surface defects. CONSTITUTION: The rolling mills for sheets or plates that comprise a pair of top and bottom work rolls that roll sheets or plates, intermediate rolls that support the work rolls respectively and back-up rolls that support the intermediate rolls respectively. In the rolling method of these mills where part of the work rolls near one end is tapered and they are arranged oppositely along roll axis, there are the advantages that in rolling sheets or plates with same width, the position at the axial direction of the work rolls can be adjusted to a pre-determined position, and the crosswise thickness distribution of rolled stock can be controlled due to changing the position at the axial direction of the intermediate rolls.
摘要翻译：目的：提供能够大大改善边缘下降的板材或板材的轧机方法和设备，有效地减少其变化和持续的轧制操作，而不会形成表面缺陷。构成：用于片材或板材的轧机，其包括一对辊板或板的顶部和底部工作辊，分别支撑工作辊的中间辊和分别支撑中间辊的支承辊。在这些轧机的轧制方法中，一端的工件辊的一部分是锥形的并且它们沿着辊轴线相对地布置，其优点在于，在具有相同宽度的轧制板或板中，在工件的轴向方向上的位置辊可以调节到预定位置，并且可以通过改变中间辊的轴向位置来控制轧制坯料的横向厚度分布。

摘要： A strip rolling mill includes a pair of upper and lower work rolls (1A, 1B) for rolling a strip (19), intermediate rolls (2A, 2B) for supporting each of the paired work rolls, and back-up rolls (3A, 3B) for supporting each of the intermediate rolls. Each of the work rolls (1A, 1B) is provided with a tapered portion (4A, 4B) at a vicinity to one end thereof in such a way that the tapered portions of the work rolls are on opposite sides of roll bodies thereof with respect to roll axis directions. The rolling method for the strip rolling mill comprises the steps of: when the material (19) with a constant width is being rolled, setting axial positions of the work rolls (1A, 1B) at appropriate positions and changing axial positions of the intermediate rolls (2A, 2B) to control a thickness distribution in a width direction of the material (19) being rolled. This arrangement significantly improves an edge drop and at the same time minimizes edge drop variations, thereby preventing surface defects from occurring on the surface of the material being rolled and performing an efficient rolling operation.
摘要翻译：一种带材轧机包括用于轧制带材（19）的一对上下工作辊（1A，1B），用于支承每对成对工作辊的中间辊（2A，2B）和支承辊（3A， 3B）用于支撑每个中间辊。每个工作辊（1A，1B）在其一端附近设置有锥形部分（4A，4B），使得工作辊的锥形部分相对于其辊体的相对侧卷轴方向。用于带轧机的轧制方法包括以下步骤：当轧制具有恒定宽度的材料（19）时，将工作辊（1A，1B）的轴向位置设定在适当位置并且改变中间辊的轴向位置（2A，2B），以控制被轧材料（19）在宽度方向上的厚度分布。这种布置显着改善了边缘下降并且同时使边缘下降变化最小化，由此防止在被轧材料的表面上发生表面缺陷并且执行有效的轧制操作。＆lt;图像＆GT;
