摘要: 分析了重轨万能轧制精轧机组UR、ER/EF和UF三机架的变形特点,并建立了相应的数学模型。对U71Mn钢(%:0.7C、1.0Mn、0.1Cr)60 kg/m重轨的连轧计算结果表明,模拟值接近设计值,轨头和轨底宽度中间道次误差分别为0.13%~0.66%和0.45%~1.3%,较好地反映了轧件轨头和轨底宽度的变化趋势。

Abstract: The deformation characteristics of UR, ER/EF and UF three racks of universal tandem finishing-rolling heavy rail are analyzed and the correspondent math models are established. The calculated results for tandem rolling of steel U71 Mn (% : 0. 7C, 1. 0Mn, 0. 1 Cr) 60 kg/m heavy rail show that the simulated value is quite close to the design value, the errors of width of rail head and base in middle passes are respectively 0. 13% ~0. 66% and 0.45% ~ 1. 3% , which better reflect the variation tendency of width of rail head and base of rolling stock.
