相变对两相区连续退火带钢温度和屈曲变形的影响
Effect of phase transformation on temperature and buckling of continuous annealing strip in two-phase region
摘要
Abstract
Low-carbon Al-killed steel was selected and finite element method (FEM) was used to investigate the influence of phase transformation on strip temperature distribution and buckling in the heating and slow cooling sections of the continuous annealing furnace. The results show that in the heating section, phase transformation can inhibit the increase of transverse compressive stress caused by thermal stress and reduce temperature and transverse temperature difference of strip effectively, and thus it is helpful to prevent the strip buckling. Inhibition of phase transformation on strip buckling firstly increases and then decreases when annealed at 760−820 ℃. In the slow cooling section, phase transformation weakens the decrease of transverse compressive stress caused by thermal stress and reduces temperature of strip, which promotes the probability of strip buckling. Strip buckling is more likely to occur at higher annealing temperature.关键词
