AI Technical Summary

Problems solved by technology

There are many steel grades that need temperature-controlled rolling in stainless steel hot-rolling plants. When temperature-controlled rolling is performed on such steel grades, temperature-controlled rolling is performed manually, such as starting rolling temperature, cooling temperature, finishing rolling temperature, etc. , and the difference in individual rolling levels is difficult to ensure the high level and high control accuracy of temperature-controlled rolling. Since the properties of steel billets cannot be measured during rolling, only a small batch of samples of steel plates can be randomly inspected after the final rolling of the steel plates. For testing, most of the steel plates are sent directly to the user without real-time records, so once the performance problems of the steel plate appear during the use of the user, it is difficult to deal with the aftermath, and it is not conducive to the further improvement of the quality of the steel plate
