Abstract Because the traditional rolling force model based on Hirschberg formula is not suitable to temper rolling, through regression of many practical data and theoretical analysis, considering technologing features and practical situation, and the effect of rolling speed, deformation resistance, tension, elongation, and other technological parameters, the flat interface between rollers and strip, based on W.L.Rorbts′s temper rolling force model, a set of temper rolling force models with the scheme of self study and self adaptation was estallished and used on 1220 temper rolling mill at Baosteel , the error of more than ninety five percent of forecast values was less than ten percent.So the model can be popularized.
