Problems solved by technology

Due to the deviation of the welding seam of the cylinder body, after a certain period of kiln operation, the cylinder body of the rotary kiln is corroded by the chemical substances in the clinker, and the weld seam is unclear, which will lead to inaccurate circumferential deviation of the kiln brick masonry. The deviation is large, the brick lining and the kiln body are not concentric during the kiln operation, the stress inside the brick lining cannot be evenly distributed on the entire lining and each brick lining, and a certain position or area of ​​stress concentration will cause refractory bricks in this part Damage, leading to risk of brick lining falling down and kiln shutdown, thus causing process accidents and economic losses

Example Embodiment

[0018] It should be understood that the specific embodiments described herein are intended to illustrate and explain the invention and are not intended to limit the invention.

[0019] In the present invention, the orientation including the term "inward" or the like in the terminology is only the orientation of the term in conventional use, or as a commonly known known to those skilled in the art. It should not be considered as limiting of the term.

[0020] The present invention provides a method of finding a refractory brickwork in kiln, characterized in that the refractory brickworking method of the kiln is included:

[0021] 1) After the rotary kiln is positioned, find the horizontal plane, set the first longitudinal reference line, the first longitudinal reference line along the long-term length of the "m" pattern, each of the first longitudinal reference line and kiln The longitudinal reference line is parallel (and also parallel to the kiln axis);

[0022] 2) According to the

Abstract

The invention discloses an alignment method for masonry of refractory bricks in a kiln, which comprises the following steps: 1) after a rotary kiln is positioned, finding out a horizontal plane, setting eight first longitudinal datum lines which are symmetrically arranged along the circumference of the kiln according to a shape like a Chinese character'mi ', and each first longitudinal datum line is parallel to the longitudinal datum line of the kiln; (2) marking out annular datum lines and a construction control line according to the first longitudinal datum line, wherein the annular datum lines are parallel to each other and are perpendicular to the axis of the kiln; and (3) the first brick is started to be built, other bricks are continuously built, the interface between rings of the built bricks needs to form a vertical angle with the axis, and the building process is based on the annular datum line and the construction control line. According to the in-kiln refractory brick masonry alignment method, accidents and economic losses caused by kiln shutdown due to damage of kiln refractory bricks caused by stress concentration can be reduced.
