Temperature Field Research and Optimization of Different Cooling Method s for Hot Rolled H-beam
Controlled cooling of H-beam after rolling can not only improve strength but also save energy.In order to improve the cooling temperature field of hot-rolled H-beam after rolling,this paper uses finite element numerical simulation to study the temperature field of hot-rolled H-beam under different controlled cooling processes,and obtains a relatively uniform temperature field through differential cooling methods.The results showed that after targeted strengthening cooling of the tran sition rounded corners of H-beam,the overall temperature di stribution of the H-beam section was relatively uniform.After 6 seconds of cooling,the temperature difference between the web and transition rounded corners was less than 45 ℃.
