Research on the out of Square of H-beams

摘要：

　　H-beam will inevitably produce temperature uneven in cooling process,causing the uneven deformation phenomenon in H-beam cross section,and therefore how to improve H-beam cooling distortion uniformity become a research priority of H-beam.In this paper,the deformation of H-beam was simulated in the cooling process by using finite element analysis software ANSYS,and the simulation results was compared with measured data.Uneven cooling rate between up and down groove of the H-beam caused the out of square.Uneven cooling rate for the R corner and web surface was simulated,the conclusion is that uneven cooling rate for the web is the main reason of the out of square,and that of R corner is the second factor.
