Material and Metallurgy Institute, Wuhan University of Science and T echnology, Wuh an 430081, China; 2 . Medium Plate Mill , Wuh an Iron and Steel Co. Ltd. , Wuhan 430083, China) Synopsis:Two kinds of mathem atical model to calculate the rolling pressure of medium plate were established . A com- p arison of the calculated valu es w ith measured ones for the rolling pressure show ed that the relative deviation of calculated valu e with Eckerlond. s rolling force model is around 10 % ~ 20 % , while the deviation of calculated valu es with Sims. rolling force model is less than 10 % . Theref ore, Sim s. model is better f or use to predict the rolling pressure. Keywords:rolling pressure; m athematical model; deformation resistance 1 , , , , , , , 2. 1 , [ 1] , P ,
