The first pass hot rolling process of compact strip production of 1 500 mm x 68 mm thin slab at Baotou Iron and Steel has been simulated by Marc commercial software with the aid of elastic-plastic thermal-mechanical coupled finite element method (FEM) . And the distribution and change of equivalent stress field
strain field and strain rate of rolling stock deforming region were analyzed. The results showed that in rolling stock deforming zone the equivalent stress gradually increased along the direction of rolling and came to maximum value (95.20 MPa) nearby neutral face
than gradually decreased; the equivalent strain also gradually increased along the direction of rolling and came to maximum value (0.70) at outlet of workpiece; and the equivalent strain rate had a maximum value nearby surface at inlet of workpiece that was 20.74 s
