Refractory-brick prefabricated member for rotary kiln

Abstract

The invention discloses a refractory-brick prefabricated member for a rotary kiln. The refractory-brick prefabricated member comprises a fourth positioning block, a refractory brick body, a third through-hole and a fourth positioning hole. A first positioning block and a second positioning block are arranged at the top end of the refractory brick body, the first positioning block is arranged on the left side of the second positioning block, a first positioning hole and a second positioning hole are formed in the bottom of the refractory brick body, and the first positioning hole is formed in the left side of the second positioning hole; a third positioning hole and the fourth positioning hole are formed in the left side wall of the refractory brick body, the third positioning hole is formed above the fourth positioning hole, and a third positioning block and the fourth positioning block are arranged on the right side wall of the refractory brick body; and a first through-hole and a second through-hole are formed in the top end of the refractory brick body, and the third through-hole is formed in the right side wall of the refractory brick body. According to the refractory-brick prefabricated member for the rotary kiln, the bricklaying is convenient, the bricklaying construction of a kiln body is convenient, the structure is scientific and reasonable, and the connection is firm; and the refractory-brick prefabricated member further has an excellent heat-insulating capability, and the service life and the quality can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of refractory brick production, in particular to a prefabricated refractory brick for a rotary kiln. Background technique [0002] The refractory brick prefabricated part is a kind of unshaped refractory material, which is generally used in the masonry of the rotary kiln. The refractory brick body needs to withstand large temperature changes and heat flow impacts during use, so the structure is required to be tight without cracks. In addition, it is required to protect the heat energy in the kiln as much as possible to prevent the loss of capacity. The existing refractory bricks are not only compact in structure, but also prone to cracks under the impact of heat flow, which is difficult to achieve. Requirements, but it is difficult to guarantee the service strength when using the castable body completely, and it is prone to fragmentation and collapse, which affects the safety of use. Therefore, the requirem...
