Abstract：

Folding surface appears in the screw groove diagonal rolling for spherical cast iron,but without it in rolling steel.The mechanics model is set up for the section caused folding surface and the new algorithm of shearing stress for the corresponding metal surface are produced,as being the one of the design rules.The mechanics basis is present to resolve the folding surface.On the one hand,it enriches the theory of rolling spherical cast iron,on the other hand,the theoretical basis is also provided for the engineering designers.
