Investigates the width prediction and setup of strip in rolling passes in a hot strip mill.
研究带钢热连轧生产线中成品带钢的宽度预报与设定。
Generally a number of rolling passes are required in the whole process, because the metal must be reduced gradually to the final shape required.
一般说来，整个轧制过程要经过许多道次的轧制，因为金属必须经过逐步压缩，才能得到最后所需的形状。
FEM and industrial rolling test are used to study the deformation behavior of square billet and round billet in diamond and square passes. The deformation for different rolling processes is compared.
