Steckel mill production technology and product development

Production process features and technical advantages of 3500 mm-Steekel mill of Anyang Steel are brielly introduced. The production line using jumbo slab accompanied by single stand Steckel hot rolling mill, as compared with the conventional plate mill, in the production ol thin-wide specifications that have unique advantages, but the rolling pass interval long time will bring technical difficulty to produce high-quality thin gauge sheet width. At the same time, compared with the conventional thick slab, the low compression ratio as the result of medium slab will bring technical difficulty to produce high-quality plate. At Steckel mill production and technical conditions, by component design and optimization ol healing system, recrystallization zone controlled rolling and non-recrystallization zone controlled rolling technical parameters, to achieve the precise control rolling for the wide thin steel plate and structure refinement of full process control for the thick plate, so as to achieve the development of high-quality steel products purpose. For Steckel mill, on the basis of the high-quality wide thin steel plate product development, the thick pipeline steel and high-strength construction machinery steel have also been produced, so the Steckel mill's unique advantages has formed in producing thin steel plate width.
