Abstract

Abstract:

Continuous casting intelligent manufacturing requires thinning the thickness of the tundish cover and increasing the baking hole.In order to solve the problems such as the overall strength of the steel structure,high temperature deformation and poor heat insulation performance,the modification design of the steel structure for tundish cover was optimized.After the on-site verification,the service life of the cover is increased from 42 days to 85 days,and the surface temperature of the cover is reduced by about 180 ℃.

Key words: Tundish, Cover, Optimization, , Castable
