ABSTRACT:
A ladle or other vessel for containing molten metal, for example molten steel, is lined with refractory at least some of which (e.g. in the slag line area) is unfired refractory bonded with a phosphate bond such as a long-chain glassy polyphosphate and containing, at least in the material smaller than 0.15 mm (-100 mesh), a high-lime periclase grain. This type of refractory shows unexpectedly high resistance to erosion and corrosion in the environment of a steelmaking ladle.
