Abstract
An improved castable refractory composition having excellent resistance to attack from slag can be efficiently transported to a destination, such as a mold, using a pump. The castable refractory composition includes about 36-92% by weight silicon carbide, about 8-20% by weight of a colloidal silica binder, and a balance substantially of other refractory materials which can include alumina, microsilica, graphite, and a setting agent. The composition of the invention can be used alone or in addition to a conventional refractory casting material to form a refractory lining. When used together, the conventional refractory composition is used to construct a lower layer in the refractory lining, and the composition of the invention is used to construct an upper refractory layer above the lower layer.
