Abstract：Flat wire is widely applied , but there is few studies about its rolling force formula at home and a-board.This article develop the Stone formula from the wire deformation rate , contact area of wire and roll con-tact to make it suitable for circular cross section of the wire flat rolling .Change deformation rate expressed with wire of cross-sectional area deformation rate instead of thickness reduction in Stone formula , and fitting out the nonlinear equation;make a hypothesis that the contact shape of wire and roll is ellipse and derive the contact area influence coefficient S .Combined with the improvement of the two aspects of Stone formula the formula is obtained after optimization .The rolling process were determined by numerical simulation and experiments , the extraction of rolling force compared the result analysis , a formula of the improved can improve the calculation precision of rolling force greatly , it is of great significance to the actual project application .
