Abstract

The invention relates to a refractory material, in particular to high-alumina fine fireclay, which solves the problems that fireclay used by a kiln in the laying industry in the prior art has poor fluidity and is easy to shrink after calcination. The high-alumina fine fireclay consists of the following raw materials in weight percentage: 46 to 52 percent of bauxite chamotte powder, 3 to 5 percent of sodium carboxymethyl cellulose, and the balance being water. The kiln laid by using the high-alumina fine fireclay basically can not be shrunk due to the fireclay, and is subjected to zero deformation basically, so that the service life of the kiln is exponentially prolonged and the production cost of the product is reduced.

Description

technical field [0001] The invention relates to a refractory material, in particular to a high-alumina fine refractory mud. Background technique [0002] The manufacturing method of industrial calcining kilns is generally to build layers of refractory bricks. In order to ensure the tightness of the kiln, refractory bricks with smooth surfaces must be selected, and then bonded with fireclay layer by layer. Refractory bricks become a whole. The refractory brick layer varies according to the number of kiln floors. The fire clay currently used as a binder is generally composed of high-alumina clinker powder, high-alumina raw meal powder, clay powder, and water. Although this kind of fire clay can also play the role of bonding and sealing, many problems have been found in actual use. First, the adhesive contains a large amount of free water, and the adhesive will be burnt by the refractory brick after contacting it. Pore ​​absorption of bricks leads to poor fluidity and poor du...
