Abstract
The present invention discloses a low density basic refractory lining material with improved resistance to corrosion by molten slag and metal that is especially adapted for use as a disposable liner in molten metal containing vessels. This material incorporates hollow ceramic microspheres of alumina, silica or mixtures thereof, having diameters of between about 5 and 500 microns as a density reducing material. This material may also include a stiffening agent, a set retarding agent, a foaming agent to further reduce the density, a plasticizer, and a low temperature binder. The addition of the ceramic microspheres has been found to provide reduced open porosity, improving resistance to corrosion. Also, the invention relates to methods for applying the disposable lining and vessels which include the lining applied thereon.
