Problems solved by technology

The disadvantage of this kind of masonry method is that as long as one brick on the first floor of the working layer is washed out, the adjacent bricks will loosen and fall off soon, so that all the bricks in this layer will fall off, which will shorten the life of the feeding chamber of the rotary kiln and increase the cost of production

Embodiment 1

[0015] In the 750t rotary kiln, the insulation layer 1 of the feeding slope of the feeding chamber is built with lightweight clay bricks; the working layer 2 is built with phosphate high-alumina bricks in a large vertical way.

[0016] The masonry method of refractory bricks on the feeding slope of the feeder is changed to: build the insulation layer 1 according to the designed thickness; The original two-story side vertical refractory bricks were changed to one-story large vertical masonry (that is, the working surface was changed from 300×75 to 150×75), and the thickness required by the design was guaranteed to be 300mm thick.

Embodiment 2

[0018] In the 600t rotary kiln, the insulation layer 1 of the feeding slope of the feeding chamber is built with lightweight clay bricks; the working layer 2 is built with fired clay bricks in a large vertical way.

[0019] The refractory brick masonry method for the feeding slope of the feeding room is changed to: build the insulation layer 1 according to the designed thickness; The refractory bricks of two-layer side vertical masonry are changed to one-story large vertical masonry (that is, the working surface is changed from 230×65 to 115×65), and the thickness required by the design is guaranteed to be 230mm thick.

[0020] In fact, as long as refractory bricks are used for masonry and the cutting slope is subject to strong material erosion, no matter what kind of products are produced, refractory products of corresponding length can be produced according to the design thickness requirements. Large vertical masonry methods can be used to achieve The purpose of prolonging t...

Abstract

The invention relates to a masonry method of firebrick, which is applied to a slope work layer built by a refractory product. The work layer has a big vertical masonry structure reaching the design thickness requirement, and the work layer is in a one-layer structure; and the bottom of the slope work layer is a thermal-protective layer built by light clay bricks. The method of the invention is the same with the traditional masonry mode on material cost, but can prolong the service life of the baiting slope of a rotary kiln feed compartment, reduces production cost and brings considerable economic benefit.

Description

technical field [0001] The invention relates to a masonry method, in particular to a refractory brick masonry method. Background technique [0002] At present, the equipment for producing lime and cement is mainly a rotary kiln. The rotary kiln is generally composed of a preheater, a feeding chamber, a kiln body, a discharging chamber and a cooler. The masonry of refractory materials in the rotary kiln is divided into working layer and heat insulation layer. The working conditions of refractory materials in the working layer are quite harsh. They not only have to bear the effects of high temperature and strong chemical erosion, but also have many effects such as fluctuations in material temperature, impact and erosion of materials. [0003] The material is preheated by the exhaust gas discharged from the kiln body in the preheater, and then enters the kiln through the feeding chamber for firing, and then is discharged from the discharging chamber to the cooler after being ...
