For the past decades,rolling models have been applied based on the rolling mill types.There is no unified rolling force/power model in the industrial and academic fields.The original von Karman equation was derived from the force equilibrium condition without any special assumptions.Hence,the unified solution should exist if no special assumptions are introduced in the solving routine.This article proposes a unified rolling force/power model by solving von Karman equation on the elastic foundation whose unit spring constant is obtained from Hertzian contact equation.This new developed solution can be applied to all rolling mill types.
