Abstract
High-strength refractory casting compound for monolithic furnace linings, consisting of refractory, durable, granular filler, reactive alumina, high-grade calcium aluminate cement and silica sol as the only liquid to provide castability and ceramic bond. The addition of 6 to 10 parts by weight of a 40% silica sol, i.e. containing 3.6 to 6 parts by weight water, per 100 parts by weight dry material mixed as above is suitable, the reactive alumina constituting 5 to 15 parts by weight and the high-grade calcium aluminate cement constituting 1.5 to 5 parts by weight of said dry material.
