Abstract In order to explore the model driven and human-interactive technology for shape display of virtual strip and component motion of virtual mill,a virtual reality modeling technology was presented based on the Elevation Grid node of VRML with the outlet strip tension transverse distribution and buckling distinguishing model of the cold rolled strip. And the quantitative analytic prediction and presentation of 3D dynamic visualization of side shape and intermediate shape defects are realized. The measured data obtained in the exit of 2 230 mm tandem cold mill group in a domestic factory has been used to verify the prediction results of the defect geometric parameters on the shape defects and buckling distinguishing model,the comparison results show that they are in good coincidence. And then, aiming at the 650 mm UCM single stand reversing cold rolling mill,with the help of the toolbox of MATLAB/ Simulink 3D Animation, the rolling mill, strip, workshop and the Simulink model of rolling process were integrated which provide foundation to the virtual reality system development for cold rolling process.
