中间包内衬用半轻质莫来石浇注料的开发

Abstract

Abstract:

There are three forms of heat loss of molten steel in tundish,they are heat dissipation from upper surface of tundish,heat storage of tundish lining and heat conduction through lining to tundish shell.This paper develops long\|life semi-light mullite castables by optimizing tundish lining material and structure,and acquires a set of technologies of safety,stability,long service life,energy saving and heat preservation,which can reduce the temperature drop and temperature fluctuation of molten steel during tundish casting and improve the quality of billet.

Key words:

"> Mullite castables, Tundish, Casting, Service life
