The Nippon Steel Corporation has long been realizing the necessity of developing an automatic rolling system of H-shapes. In an attempt to complete a new automatic system, not only mathematical models but also various sensors were first studied by the Nippon Steel Corporation.
Based on these achievements, we have successfully realized a dynamic computer control system for rolling H-shapes for the first time.
The new system comprises an automatic rolling system of universal mills of H-shapes and various subsystems which support the main system. The main role of the automatic rolling system is to determine optimum conditions of rolling.
The system makes it possible to roll H-shapes uniformly in quality and get the required high-level quality of H-shapes.
