| Abstract: | Aiming at the defects of process design for large H beam blank casting tundish,developed and applied dual sizing nozzle quick changing technology, flow field optimizing technology, flow control device longevity technology for beam blank casting tundish. Through technology integration and innovation, with the formation of independent intellectual property of the beam blank packet technology,the percent of pass of slab reached more than 99.80 %, tundish sequence casting time reached more than 36 hours. |
