Entering 2025, the topic of “AI intelligence” has become a hot search, triggering heated public opinion in the whole society and various industries. From government affairs to industry and service industries, “AI intelligence” systems mainly based on DeepSeek have been successively integrated. In the traditional heavy industry of the steel industry, the maintenance workers at the grassroots level of Delong Steel have also transformed their traditional thinking. By consulting with AI, comprehensively and systematically analyzing problems, identifying and filling gaps, and providing new ideas, they have begun to enjoy the “dividends” brought by AI changing lives and production.

AI provides comprehensive advice. At the 3 # oxygen production air through oil station in the power plant, the inlet filter of the 3 # air separation air through filter is located at the lower air outlet of the exhaust fan, causing the discharged oil fume to adhere to the paper filter element of the filter, reducing the efficiency of the filter element and affecting the service life of the equipment. In the early stage of the power plant, in order to solve this problem, the smoke exhaust pipe was longitudinally raised in the hope of carrying the raised oil fume to a distant place through the wind. However, the final effect was not ideal and the problem was not completely solved. Huang Yuxiao, a technician in the maintenance workshop of the power plant, had a sudden idea when he saw “AI intelligence”. With a trial and error attitude, he submitted the problem that was troubling them to AI and unexpectedly achieved remarkable results. DeepSeek analyzes from four perspectives: spatial layout, oil fume purification capability, filter protection measures, and oil fume volatilization, and provides improvement suggestions. Huang Yuxiao, based on the actual situation on site, learned from the experience of the first failure and followed the suggestion to take two measures. Firstly, install a purifier at the front end of the exhaust pipe, connect it to the oil drum, and absorb heavier oil droplets; The second is to extend the pipeline horizontally, completely away from the inlet filter of the 3 # air separation system. Through the joint efforts of the maintenance technicians, the second renovation was successfully completed. After a period of operation, the effect was good and the problem was completely solved.

Open up ideas, encyclopedia. The 3 # air separation turbine compressor mainly sucks in air for compression, and provides the compressed air to the next process for separation into liquid nitrogen, liquid oxygen, and liquid argon. Inhaling air inevitably results in the inhalation of dust. The original filtering device is ineffective, and dust accumulates and adheres to the compressor rotor and pipeline walls, corroding equipment and pipelines, causing dynamic balance failure, and ultimately leading to equipment vibration failure. When Huang Yuxiao regarded “AI intelligence” as a friend and an encyclopedia, this habit also brought new ideas for solving maintenance problems. The new problem-solving approach points out that on the one hand, a filtering device is essential, and if the effect is not good, there may be improper installation or operation of filtering spare parts and filter elements; On the other hand, it is necessary to remove rust and paint the pipeline wall, increase the smoothness of the pipeline wall, and avoid dust adhesion. At the same time, it also serves to prevent pipeline rust and prevent rust from being sucked into the compressor. Huang Yuxiao organized everyone to carry out renovation according to the plan, paint and establish fixed-point inspection measures. On the basis of the original job site inspection and replacement of filter elements, maintenance backbone inspection measures were added to check whether the filter elements were not replaced after expiration or not installed properly every month. After a series of measures for improvement, this problem has been easily solved.

The application of AI in inspection and maintenance is not limited to the above two aspects, such as the modification of abnormal noise in the check valve of the condensate pump water pipeline, optimization of the evaporator effect of the air separation chiller, and repair of loose bolts in the inlet pipeline compensator, which have also received assistance from AI. AI can not only process data, write scripts and speeches, or learn foreign languages like in news reports, but it can also provide case analysis and experimental results for equipment maintenance like a mentor and friend. We need to further explore its potential and functions Huang Yuxiao said.
When steel collision data sparks new ideas, “AI+industry” is no longer a concept floating in the cloud. The “dividends” brought by AI changing lives and production also have great potential in traditional heavy industry. Every employee in a position should not be afraid that AI will replace them, just like how “Tang Monk became Tang Monk not because of the true scriptures he obtained, but because of the difficulties he experienced.” Everyone should embrace AI with a positive and open attitude, and use “intelligent solutions” to solve problems encountered in production and life, improve work efficiency, and enhance the quality of life.
