The objective of this study is to develop a novel rolling technique for size-free or material property-free rolling by controlling interstand forces in tandem rolling mill train (elongation-controlled rolling). After a prototype mill was designed and constructed, commercial metals have been successfully rolled into several sections. The obtained main results are as follows,(1) The interstand forces are changed widely from tensile to compressive by controlling roll speeds of stands independently. As a result, the elongation (or lateral spread) of materials during rolling is changed remarkably. This effect is more obvious in case of materials with smaller aspect ratio (width/thickness).(2) In case of square wires, arbitrary combinations of side length and corner radius of product are achieved with H-V-H-V-H arranged glooveless rolls by interstand force.(3) In case of H-shaped wires, the rib height of product is controlled.(4) Material rolled with tensile interstand forces shows higher tensile strength and hardness than those with compressive ones.The proposed method is concluded to an effective size-free rolling method of various products.

这项研究的目的是通过控制串联滚动磨机（延长控制的滚动）中的可式滚动力来开发一种新型的滚动技术，以通过控制无尺寸或无材料的无属性滚动。设计和构造原型磨坊后，商用金属已成功地卷成几个部分。所获得的主要结果如下：（1）通过独立控制支架的滚动速度，可实稳定性从拉伸到压缩的变化。结果，滚动过程中材料的伸长（或侧向扩散）被显着更改。在宽度比较小的材料（宽度/厚度）的情况下，这种效果更为明显。（2）在平方线的情况下，用H-V-H-H-V-H通过可实立实力安排的GloOveless卷来实现侧面长度和产品角度的任意组合。拟议方法得出了各种产品的有效无尺寸滚动方法。
