Silica brick

Abstract

The invention provides a silicon mullite brick. The silicon mullite brick comprises a brick body. The top of the brick body is provided with a through groove penetrating through the front side and the back side of the brick body, the front side face and the back side face of the brick body are provided with grooves below the through grooves, the grooves are internally provided with drainage plates, the front side face and the back side face of the brick body are provided with drainage grooves communicated with the grooves and the left side face of the brick body on the left side faces of the grooves, the front side face and the back side face of the brick body are provided with drainage grooves communicated with the grooves and the right side face of the brick body on the right side faces of the grooves, the front side face and the back side face of the brick body are provided with zigzag narrow slots communicated with the grooves below the grooves, a binding material is placed in an area defined by the grooves between two silicon mullite bricks from the drainage grooves formed in the two sides of the grooves in a filling mode, the filling amount of the binding material is constant, the binding material cannot be excessive or less, the binding range is wide, and the two silicon mullite bricks are bonded firmly.

Description

technical field [0001] The invention relates to a silica molybdenum brick. Background technique [0002] The existing refractory brick made of sillimanite mullite mainly consists of a brick body, a through groove on the top of the brick body that runs through the front and rear sides of the brick body, and a groove on the front and rear sides of the brick body that is located below the through groove. When installing, first apply the bonding material in the grooves of the two refractory bricks, and then connect the grooves of the two refractory bricks to the grooves so that the two refractory bricks are bonded together. It is prone to the problem of uneven application of bonding material, that is, when too much bonding material is applied, there will be a large gap between two refractory bricks. All will affect the service life of the assembled kiln. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a silica bric...
