Prediction Modelling and Software Developed for Microstructure and Properties of Hot-Roll Strip Steel

Based on the physical-metallurgical theory, the recrystallization, precipitation and phase transformation were modelled in the hot-rolling process of HSLA steel strip. As a result, the parameters of microstructure and properties can both be calculated quantitatively, with a software developed to predict them in accordance to actual technological process. The results showed a good agreement with those measured experimentally. What is more important is that the software can greatly save time and cost, much more that it is easy to use and maintain. So the software has good prospects in application.
