带钢热连轧非对称因素对板形的影响
Influence of asymmetric factors in hot tandem rolling on the shape of steel strips
摘要
Abstract
In order to analyze the influence of asymmetric factors on the shape ( such as wedge and single edge wave) of rolled pieces in 2250 mm hot tandem rolling, an asymmetric shape calculation model involving rolls and rolled pieces was established, which is integrated by a roll deformation calculation model based on the influence function method, a transverse distribution model of tension stress and a simplified transversal distribution model of rolling force. The results show that the wedge of incoming pieces has a greater effect on the wedge of rolled pieces than on the flatness. The stiffness asymmetry of up-stream stands and down-stream stands mainly affect the wedge and flatness of rolled pieces, respectively. A temperature difference of rolled pieces within 40℃ has a little effect on the flatness and has negligible effect on the wedge. The deviation of rolled pieces affects both the wedge and flatness dramatically. The admissible ranges of asymmetric factors were determined with a target of achieving a good strip shape.关键词
