Abstract:In order to improve the functional accuracy of sector section and reduce the internal and external quality problems of continuous casting slab, the functional accuracy of sector section has been well controlled and the internal quality and surface quality of slab have been improved by means of compensation check of sector section tie rod, optimization of mechanical structure of sector driving roll, optimization of accumulated assembly error of sector section and optimization of accuracy of roll gap measuring instrument. The results show that the central segregation and surface quality of slab are closely related to the functional accuracy of sector section. Strict control of roll gap and arc in sector section can effectively reduce the central segregation and surface quality of slab.
