Embodiment 1

[0014] Embodiment 1, as shown in Figure 1, a method for replacing the refractory bricks of a specific diameter in a cement rotary kiln is characterized in that: comprising the following steps to complete:

[0015] First, the standard bricks are divided into 2 pieces as shaped bricks according to the number of ring proportions; then the modified bricks are cut according to the actual size; longitudinal joints are used for masonry, and two staggered wet masonry are used;

[0016] Cutting requirements for processing bricks:

[0017] When processing alkaline bricks, dry cutting is required, the side with cardboard should be kept, and the side without cardboard should be processed. Under normal circumstances, the cardboard on the brick side should not be torn; silicon molybdenum bricks and anti-peeling bricks can be wet-cut with water; cutting error≤ 2mm; when processing 100mm shaped bricks, pay attention to cutting from the center line along the length direction to ensure that bot...

Abstract

The invention discloses a building method for replacing refractory bricks with a specific diameter in a cement rotary kiln. The building method is characterized by comprising the following steps that firstly, a standard brick is equally divided into two blocks to serve as sizing blocks according to a ring ratio block number; secondly, a deforming brick is cut according to a practical size; and a longitudinal straight joint is adopted during bricking, and bricking is conducted on the two cut refractory bricks in a staggered wet method. The building method has the beneficial effects that due to the fact that the staggered wet method is adopted for conducting bricking on the replaced refractory bricks in the cement rotary kiln, when a lengthened brick which is 300 mm in length is not available at the end of bricking, the method is adopted for ensuring firmness and reliability of the refractory bricks in the cement rotary kiln, and the service life of the cement rotary kiln is ensured.

Description

technical field [0001] The invention relates to a method for replacing refractory bricks with specific diameters in a cement rotary kiln. Background technique [0002] At present, when the refractory bricks are replaced in the cement rotary kiln, at the end of the masonry, there is always a section that needs to be connected with the old bricks in the latter section; when the size is >100<200, standard bricks can be used for processing, but often encountered In the case of size > 200 < 300, when there is no 300 elongated brick, the following scheme can be used for processing and masonry. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method for replacing refractory bricks with a specific diameter in a cement rotary kiln, so as to solve the problem of replacing refractory bricks in a cement rotary kiln. The problem of building refractory bricks. [0004] The technical scheme adopted by the present invention to solve its ...
