Abstract

The invention discloses an energy-saving composite refractory brick and relates to a refractory brick. The energy-saving composite refractory brick comprises a work layer, a refractory material layer and a heat insulating layer, wherein the work layer is coated with a paint with high radiation energy; bonding surfaces among the work layer, the refractory material layer and the heat insulating layer are concave-convex surfaces, and the work layer, the refractory material layer and the heat insulating layer are in seamless connection with one another; at least two cylindrical cavities are arranged in the refractory material layer; the heat insulating layer is made of light material; the cavities are filled with a thermal insulating material, and both the refractory material layer and the heat insulating layer are added with mullite granules. The energy-saving composite refractory brick has the advantages that the dissipation of heat in a kiln can be reduced, energy is saved, and the service life of the kiln is prolonged.

Description

technical field [0001] The invention relates to a firebrick for building, in particular to an energy-saving composite firebrick. Background technique [0002] At present, the refractory bricks used in the lining of high-temperature kilns are bricks made of high-temperature-resistant materials as a whole. Since the temperature in high-temperature kilns is generally above 1600 ° C, after a period of use, the bricks will be damaged. The furnace charge is damaged by friction and scouring and must be replaced. The service life of kiln body will be very short like this, just causes the waste of resource. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an energy-saving composite refractory brick, which can reduce heat loss in the kiln, save energy, and prolong the service life of the kiln body. [0004] In order to achieve the above object, the present invention is achieved through the following...
