Masonry method for rotary kilns

Abstract

The invention discloses a masonry method for rotary kilns. The masonry method includes steps of (1), dividing areas; (2), welding anchoring parts; (3), mounting precast bricks; (4), pouring mortar. The masonry method has the advantages that integral precast brick layers are divided into a plurality of areas, when the precast bricks in a certain area fall off, the integrity of the other areas can be guaranteed, accordingly, the cost can be saved, and workload on workers can be reduced; mortar joints are reserved among the various adjacent precast bricks, so that the integrity of the rotary kilns can be corrected, and accidents caused by the fact that only refractory mortar in joints is squeezed when existing precast bricks are heated and expanded, and the existing precast bricks are squeezed by one another, are broken and fall off can be prevented; the precast bricks are fixed to kiln bodies by the aid of the anchoring parts, so that joints among the precast bricks and the inner walls of the kiln bodies can be set and prevent the precast bricks from squeezing the inner walls of the kiln bodies when the precast bricks are radially expanded, and accidents caused by the fact that the inner walls of existing kiln bodies are squeezed by the existing precast bricks and anchoring parts are broken can be prevented.

Description

technical field [0001] The invention relates to a masonry method, in particular to a rotary kiln masonry method. Background technique [0002] Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants in the metallurgical industry; oxidative roasting of chromium and nickel-iron ore; roasting of high-alumina bauxite in refractory plants and clinker and aluminum hydroxide in aluminum plants; roasting of chromium ore in chemical plants And minerals such as chromium ore powder. Lime kiln (i.e. active lim...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies of the above-mentioned prior art, provide a rotary kiln masonry structure and a masonry method, and solve the problem that in the existing masonry method, prefabricated bricks are directly welded on the kiln body. The feet are easy to break, and the prefabricated bricks are all close together. If one of the prefabricated bricks has a problem, all the prefabricated bricks may become loose. All the prefabricated bricks need to be inspected and rebuilt, which takes a lot of time and cost
