Types and Characteristics of Refractory Materials for Tundish Lining
The tundish is situated between the ladle and the continuous casting machine, featuring both a rectangular and T-shaped design. The refractory materials used for lining the tundish are varied. The permanent layer castable is composed of high-alumina bricks, forming a cohesive structure. The working layer is fitted with a thermal insulation board, smearing material, and is integrally cast with dry castable. The materials used can be acidic, neutral, or alkaline. The tundish features a simple structure with a bottom and walls. Additionally, it includes nozzles and impact areas at the bottom, as well as overflow grooves or retaining walls along the side. The tundish is the refractory lining that is the most frequently overhauled in steel plants. It must be used for future development, and the construction is quick and convenient. The permanent layer of the tundish is also made of high-aluminum castable, which is installed or painted as needed....
