Abstract
The invention discloses a red mud alkali resistant refractory castable. The castable comprises red mud, flint clay aggregate, flint clay powder, calcium aluminate cement, explosion-proof fiber and a water reducing agent. The castable is characterized by rational structure, high strength and stable high temperature performance. Industrial furnaces constructed by using the red mud alkali resistant refractory castable have the advantages of material erosion resistance, wear resistance, alkaline corrosion resistance and long service life in high temperature operation.
Description
Technical field
The invention belongs to a kind of amorphous refractory, specifically is a kind of red mud alkali resistant refractory castable.
Background technology
Red mud is to refine the industrial solid castoff of discharging behind the aluminum oxide from bauxite, produces one ton of aluminum oxide and will discharge 1.0-2.0 ton red mud, and along with improving constantly of aluminum oxide output, the quantity discharged of red mud constantly increases.At present, about 7,000 ten thousand tons of the annual red mud that produces in the whole world, the annual red mud that produces of China is more than 2,000 ten thousand tons.Because a large amount of red muds is not fully utilized, and can only stack processing.The stacking of red mud is the land occupation resource not only, expends more stockyard construction and maintenance cost, and destroys ecotope, cause serious pollution, harm physical environment and human health, the useful composition of red mud can not get using simultaneously, also is a kind of waste of resource.
