Effective treatment method for solving uneven consumption in rotary kiln

Abstract

The invention discloses an effective treatment method for solving uneven consumption in a rotary kiln. The effective treatment method comprises the following steps: 1) determining a patching point in the rotary kiln; and 2) digging two rings of bricks firstly, building one ring of bricks, and then digging one ring of bricks till the last ring is sealed; wherein the thickness of the brick at the patching part is less than 1 / 2 of the thickness of the original brick, and the patching degree is that the thickness of the brick at the peripheral old brick is 2 / 5 of the thickness of the original brick. The effective treatment method can improve the repair effect of the rotary kiln.

Description

technical field [0001] The invention relates to repairing in a rotary kiln, in particular to an effective treatment method for solving uneven consumption in the rotary kiln. Background technique [0002] The refractory bricks in the cement rotary kiln are subject to mechanical stress, chemical erosion, process calcination and other influences during operation, and small-area shearing, peeling, burning and other phenomena often occur, resulting in brick loss and replacement of bricks in red kilns; but the general comprehensive service life and The thickness of the surrounding bricks should be taken into account. When digging and mending, it is often encountered that the thickness of the surrounding bricks is less than half a brick. Contents of the invention [0003] The object of the present invention is to provide an effective treatment method for solving uneven consumption in the rotary kiln, and the effective treatment method can improve the repair effect of the rotary k...

[0002] The refractory bricks in the cement rotary kiln are subject to mechanical stress, chemical erosion, process calcination and other influences during operation, and small-area shearing, peeling, burning and other phenomena often occur, resulting in brick loss and replacement of bricks in red kilns; but the general comprehensive service life and The thickness of the surrounding bricks should be taken into consideration. When digging and mending, it is often encountered that the thickness of the surrounding bricks is less than half a brick. If it is not handled properly, it will cause secondary brick loss.
