Influence of roll speed mismatch on strip

· In these investigations finite element techniques have been used to determine the effect of roll speed mismatch on the direction and severity of strip curvature in the roughing stages of a hot mill A plane strain finite element model has been constructed to simulate the rolling of low carbon steel strip at high temperatures Five ingoing strip thicknesses were considered each one
