Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the high-connection-strength alumina hollow ball kiln furnace brick provided by the utility model comprises a brick body 1, wherein the top end of the brick body 1 is fixedly connected with a clamping block 3, the bottom end of the brick body 1 is provided with a clamping groove 2 matched with the clamping block 3, one side of the brick body 1 is fixedly connected with a clamping block 4, the other side of the brick body 1 is provided with a clamping groove 5 matched with the clamping block 4, and the connection strength among a plurality of bricks can be improved through clamping of the clamping groove 5 and the clamping block 4.
