SIMULATION OF COOLING PROCESS OF HOT-ROLLED CHANNEL STEEL AFTER ROLLING

Cooling process after rolling of hot - rolled 20 # channel steel was simulated by using the finite element software, and temperature field variation rule of cooling process after rolling and temperature variation of typical sites were obtained. The simulation results was in agreement with the actual cooling process through checking with actual measurement value. This article provides a study method of cooling regularity after rolling of channel steel and provides a good theoretical basis for setting the finishing temperature and improving the cooling conditions in the cooling bed, which is conducive to en- sure product performance and reduce cooling deformation of the product. It is instructive on the formulation of rolling process in production process and the study on residual stress.
