Structure and material design of high performance functional refractories for high-speed continuous casting

摘要

Served as specific functions, functional refractories for continuous casting including SEN, ladle shroud and monolithic stopper are the key refractories for continuous casting. Driven by the demand of high-speed continuous casting, traditional functional refractories are hard to meet the needs of long span life and high performance functional refractories for continuous casting are increasingly required. Through the structure and material design, the performance of functional refractories is significantly improved. In this paper, some research advances on functional refractories for continuous casting are included. Through the numerical modeling and hot simulation, the service life of non-preheating ladle shroud are increased from 8hr to more than 12hr. Through the water modeling, the flow patterns in the mold are significantly improved and through the hot simulation and material design, the service life and reliability of SEN are also significantly improved.
