Development of Stretch-reducing Process Software for Reduction Ratio Allocation Correction Method

The conventional allocation scheme of the reduction ratio of the stretch-reducing process is corrected.And based on the interactive function of the MATLAB software,a complete set of the stretch-reducing process calculation software is developed.Taking the 20-stand,3-roll stretch-reducing mill as located at a certain domestic company as an example,the design theory of the stretch-reducing process parameters are analyzed,and the idea and the methods for the process design software are constructed,which provides such proper functions as pass design system,speed scheme,calculation of the mechanical parameters and tool parameters for the production unit.The calculated results are very close to the actual production data,which can verify the correctness and reliability of the calculation software based on the correction method.
