Abstract:The bending deformation problem and internal residual stress of hot-rolled L-beams affect the quality and subsequent use performance of L-beams. In this paper, the computational model of the L-beam air-cooling process is established by using ABAQUS finite element software, which reveals the reasons for three times deformation of the L-beam from the perspectives of phase change expansion and metal cooling contraction. In order to control the deformation and residual stress of the L-beam, four experimental schem… Show more
