Metal transverse flow and its influence factors of hot rolled strips

A new method was proposed for analyzing metal transverse flow in hot rolling processes. Firstly a static roll-strip coupling model was established by ANSYS finite element simulation software, and the work roll contour under loading was extracted from the calculation results. Secondly, with the extracted work roll contour, a dynamic roll-strip coupling model was built by ANSYS/LS-DYNA simulation software and the rolling process was well simulated, then the metal transverse flow state in the whole strip width range was solved. Besides, the influences of bend force, initial roll contours, and strip crown on the metal transverse flow were analyzed. On the basis of these analyses, a calculation model of metal transverse flow during hot rolling was obtained by an interpolation method. The model was proved to be reliable by the finite element method.
