Abstract
The production of wide and thin gauge plates by the Steckel mill could be subjected to on-line heating and holding treat-ment during the rolling process,which has the technological advantages of uniform microstructure and performance of plates and high production efficiency.The development of the equipment and technology of the 3 500 mm Steckel mill line in Rizhao Co.,Ltd.of Shandong Iron and Steel Group are elaborated,and the main achievements and innovations of the high-precision control of the thin gauge plates with ultra-large ratio of width and thickness and the digital intelligence control of the Steckel mill line are introduced.Through technological integrated innovation and development of a multi-dimensional and multi-modal digitally driven intelligent control technology for hot-rolling full-process,the high stability and high homogeneity production of thin gauge plates with ultra-large ratio of width and thickness are realized,which has brought good economic and social benefits.
