连退炉内炉辊热变形对带钢瓢曲变形的影响
Influence of roller thermal deformation on strip buckling in continuous annealing furnace
摘要
Abstract
FEM was used to investigate the influence of roller thermal deformation on the strip buckling in the heating and rapid cooling sections of the continuous annealing furnace by thermal stress calculation and buckling analysis, and the single taper roller was chosen as the original roller type. In the heating section, the roller type was changed to be the double taper roller, the single taper roller and "M" shape roller with the increase of the temperature difference, accompanied by the decrease of the total roller taper. Within certain temperature difference, the thermal deformation of roller is helpful to prevent the strip buckling. In the rapid cooling section, the single taper roller is changed to be the double taper roller after the thermal deformation and its total roller taper increases with the increase of the temperature difference. The changes promote the probability of strip buckling. Considering the roller thermal deformation, a reasonable suggestion was proposed for the temperature difference control and the type selection of roller in the heating and rapid cooling sections.关键词
