Method for prolonging service life of wicket cover

Abstract

The invention discloses a method for prolonging the service life of a wicket cover. The method for prolonging the service life of the wicker cover comprises the steps that various anchoring parts are used in cooperation, and the anchoring parts are matched to be in the optimum state; welding workers are monitored to weld the anchoring parts, so that full-length welding of the required anchoring parts is achieved, and the anchoring parts are arranged reasonably and compactly; it is ensured that the optimum mobility of a casting material is kept and the refractoriness of the casting material is not reduced. The method for prolonging the service life of the wicker cover can overcome the defects that in the prior art, the structure is unreasonable, the technological process is complicated, the labor intensity of workers is high and has the advantages that the structure is reasonable, the technological process is simple and the labor intensity of workers is low.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a method for extending the service life of a kiln door cover. Background technique [0002] The No. 1 kiln in the No. 1 branch of Yufeng Cement Co., Ltd. has a long history and is one of the few semi-dry production lines in China. Due to the high ambient temperature and design defects of the kiln door cover, the failure of the castable falling is prone to occur in the production operation, which not only affects the stability of the kiln production, but also causes dust to pollute the environment. [0003] The kiln door cover castables have been used for more than 12 months; the kiln door cover castables have been used for less than 3 months, and some of the castables have fallen off and burned through; it is necessary to extend the service life of the castables, reduce the number of kiln shutdowns and the use of castables ,save costs. [0004] After the overhaul in J...

AI Technical Summary

Problems solved by technology

[0004] After the overhaul in June 2012, in September 2012, two large high-temperature areas appeared on the south side of the kiln door cover, and personnel were organized to weld square boxes to make castables; on October 2012, three more pieces were found on the north side of the kiln door cover. High temperature area; in November 2012, two burn-through areas appeared on the northwest side of the kiln door cover. In the high-temperature area of ​​4 blocks, personnel were organized to deal with it on site for a day; when it was overhauled in January 2013, a large area of ​​steel was replaced for the kiln door cover, and a large area of ​​castable was recast

[0005] After analysis and verification, three main reasons were found: unreasonable matching of anchors; unreliable welding and unreasonable arrangement of anchors; unreasonable construction technology of castables

[0006] In the process of realizing the present invention, the inventors have found that there are at least defects in the prior art such as unreasonable structure, complicated process and high labor intensity.
