Abstract：In order to solve many equipment problems of Baosteel No. 3 heavy slab caster, such as high old failure rate, low precision of roll gap in sector section and weak soft reduction function, eliminate slab quality defects, expand slab product thickness specifications, and improve equipment technology level of continuous caster, a comprehensive technical upgrading and transformation of continuous caster was carried out. Head equipment, slab guiding equipment and dummy bar system equipment have been completely new designed and updated. Many key technologies, such as electromagnetic stirring technology of mould, have been adopted to improve the quality of slab production, to produce high quality and high added value continuous casting slab, and to achieve energy saving and consumption reduction. Especially the adoption of unmanned steel casting technology has improved the working environment of workers, reduced the number of workers, reduced costs and increased productivity, led the application of intelligent continuous casting manufacturing technology, and made the equipment technology level of continuous casting machine reach the first-class level in China and advanced level in the world.
