Description

Cement kiln with refractory bricks

Technical Field

The invention relates to a kiln for preparing cement, wherein refractory bricks are paved on the inner wall surface of the kiln chamber of the kiln.

Background

Anchoring parts are components used to connect monolithic refractory linings, refractory preforms, refractory fiber mats to furnace shells or furnace steel structures. The function of the anchor is to fix the connected lining in position to resist the effects of static loads, thermal stresses, mechanical rotation or vibrations. The anchoring piece is helpful to prevent the collapse of the material before the ceramic combination is formed in the construction and heating processes, and is also helpful to ensure that the material is uniformly shrunk and avoid the formation of large and concentrated cracks on the lining body. The existing refractory brick anchoring piece for the cement kiln has a single structure, is usually in a simple L shape or a V shape and the like, is not strong enough in stability, and is easy to cause the falling off of the inner wall of the cement kiln due to insufficient bearing capacity in the use process; and most of the existing anchoring pieces are only considered to be arranged on the inner side of the inner wall, and are not considered to be connected with external refractory material layers such as refractory bricks, so that the applicability is relatively low. Therefore, the anchoring piece for the refractory bricks on the inner wall of the cement kiln is improved, so as to meet the fixing requirement of the refractory bricks arranged on the inner wall surface of the kiln chamber of the kiln.
