Embodiment Construction

[0018] In order to explain the present invention more clearly, the pipeline cleaning process will be further described below in combination with the overall pipeline cleaning process flow and specific implementation cases.

[0019] The following are preferred implementation cases of the present invention. It should be noted that the specific conditions in the implementation cases can be determined according to actual needs and are limited to the present invention. The protection scope of the present invention shall be determined by the claims.

[0020] Take the hydraulic pipeline cleaning of slab continuous casting equipment in a steel company as an example. The material of the pipeline is stainless steel, the medium is mineral petroleum-based hydraulic oil, and the maximum size of the pipeline is Φ89*6. The pipeline is now cleaned and passivated.

[0021] Remove the original hydraulic components of the hydraulic pipeline, and connect them with hydraulic hoses to form a flushi...

Abstract

The invention relates to a pipeline cleaning process design which is mainly used for cleaning a medium pipeline of continuous casting equipment in the steel production process. The pipeline cleaning process mainly comprises the procedures of pipeline disassembly, assembly and connection, flushing, leakage testing, degreasing, primary acid pickling, secondary acid pickling, passivation, drying, waste liquid recovery, pipeline reinstallation and the like. According to the process, acid pickling and passivation processes of the medium pipeline are combined, degreasing and dual cleaning are carried out in the acid pickling process, and problems that the medium pipeline in continuous casting equipment is difficult to clean, low in cleaning quality, uneven in cleaning and the like due to many kinds of media, complex media and the like are solved. The cleaning efficiency of an existing process is improved, the cleaning cost is saved to a certain extent, waste liquid is uniformly recycled after cleaning, and the burden of chemical pollution products on environmental protection is relieved.

Description

technical field [0001] The invention relates to the field of pipeline chemical cleaning, in particular to a medium pipeline cleaning process for continuous casting equipment. Background technique [0002] The iron and steel industry is a basic industry in an industrialized country. The output and quality of steel are indicators to measure the level of national industrial development. The emergence of continuous casting technology and equipment has greatly improved production efficiency and reduced energy consumption. Compared with ordinary casting, it has obvious advantages . In the continuous casting equipment, a wide variety of medium pipelines are laid, and the main medium includes hydraulic pressure, oxygen, nitrogen, argon, compressed air, lubricating oil, water, steam, etc. Among them, the maximum diameter of the hydraulic pipeline can reach Φ89*6, and the length of the pipeline exceeds 1.1*10 4 m. Therefore, how to shorten the time for chemical cleaning of the medi...
