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.
