【摘要】：針對(duì)目前困擾熱軋中碳高強(qiáng)度寬帶鋼生產(chǎn)的橫向彎曲缺陷,使用有限元軟件ABAQUS結(jié)合FORTRAN語(yǔ)言編寫(xiě)子程序,建立熱軋帶鋼軋后冷卻有限元模型。通過(guò)模型計(jì)算,分析帶鋼軋后冷卻過(guò)程中上下表面的冷卻不均以及帶鋼厚度對(duì)帶鋼橫向彎曲的影響。研究結(jié)果表明,相同厚度情況下,帶鋼上下表面冷卻不均程度越大,帶鋼橫向彎曲程度越嚴(yán)重,上下表面相同冷卻效率比的情況下,帶鋼越厚,帶鋼橫向彎曲越嚴(yán)重。冷卻過(guò)程中,受溫度變化和相變的綜合影響,帶鋼彎曲方向和大小會(huì)發(fā)生較大變化,且冷卻過(guò)程中帶鋼彎曲量最大值遠(yuǎn)遠(yuǎn)大于冷卻結(jié)束后橫向彎曲量。
[Abstract]:Aiming at the transverse bending defects of hot rolled medium carbon high strength wide band steel, a finite element model of cooling after hot rolling strip was established by using finite element software ABAQUS and FORTRAN language to compile subprogram. Through the model calculation, the uneven cooling of the upper and lower surfaces and the influence of strip thickness on the transverse bending of strip during the cooling process after rolling are analyzed. The results show that under the same thickness, the greater the uneven cooling degree of the upper and lower surface of the strip, the more serious the transverse bending degree of the strip, and the more serious the transverse bending of the strip is under the condition of the same cooling efficiency ratio of the upper and lower surface. In the cooling process, the bending direction and size of the strip will change greatly due to the influence of temperature and phase transformation, and the maximum bending amount of the strip during cooling is much larger than the transverse bending after the end of cooling.
