Abstract The production technological features and technical predominance of 3500mm Steckel mill were introduced. The production line of Steckel mill of Anyang Iron and Steel Group Co., Ltd. adopted super-wide slab for medium plate with the single-frame Steckel mill, which had a unique advantage of wide or thin steel plate production but had some technical difficulties in producing high quality medium plate because of its longer rolling pass interval and lower compression ratio of medium slabs. Therefore, under the production specifications of steckel mill, the high quality steel plates were developed successfully by designing the compositions of steel plates and optimizing the heating rules and the controlled rolling technical parameters both in recrystallized region and unrecrystallized region. The unique advantage of producing wide thin steel plates by Steckel mill was achieved, too.
