Effects of Temperature in Continuous Annealing Furnace on Critical Load of Strip Wrinkling
The distinct performance parameters of strip material MS1470 at different temperature were obtained.The wrinkling critical load of steel at different temperatures was calculated using nonlinear static algorithm.The results show that when the material temperature is 850 ℃,700 ℃ and 600 ℃,and the critical loads are the ranges of 12～14 MPa,22～25 MPa and 52～54 MPa,the higher the heating temperature reaches,the smaller the wrinkling critical load gets,which is in line with the reality.
