Abstract

The invention belongs to the technical field of refractory bricks and particularly relates to a refractory brick. The refractory brick comprises a brick body and a clamping unit. A prefabricated hole for placing the clamping unit is formed in the brick body. Clamping columns symmetrically arranged on the basis of a vertical center line of the brick body are arranged on the top of the brick body. An arrow with a tapered section is arranged at the end, away from the brick body, of each clamping column. Recesses for placing the clamping columns are formed in the bottom of the brick body. The brick body and the clamping columns are integrally fired into one shape, and the clamping columns and the arrows are integrally fired into one shape. A cavity is formed in the upper portion of each recess, and the arrows are placed in the cavities. The clamping unit is used for fixing adjacent brick bodies when the brick bodies are stacked. The refractory brick is simple in structure; and by designing the clamping columns and the recesses in the brick body and by designing the clamping unit, the adjacent brick bodies can be relatively fixed after being stacked, so that the situation that the refractory brick falls off in use is reduced, and the refractory brick is particularly adapted to a dome of a hot blast stove.

Description

technical field [0001] The invention belongs to the technical field of refractory bricks, in particular to a refractory brick. Background technique [0002] Refractory materials are generally divided into two types, namely unshaped refractory materials and shaped refractory materials; unshaped refractory materials are also called castables, which are mixed powders composed of various aggregates or aggregates and one or more binders. Granules must be mixed with one or more liquids to be evenly stirred when used, and have strong fluidity. Shaped refractory materials generally refer to refractory bricks, whose shape has standard rules, and can also be temporarily processed when building and cutting according to needs. [0003] For hot blast stoves, refractory bricks are needed in the production process, and bricks often fall off the vault of hot blast stoves. Air leakage and fire escape are a common problem, which often causes shutdowns for maintenance. The main reason is It ...
