Chen Shaoyun, "Nanning Craftsman" in 2022, is the director of the Equipment Support Department and Maintenance Department of Nanning Float Glass Co., Ltd. After entering the factory for more than 20 years, Chen Shaoyun, with his excellent technology, could not escape from the bench worker's maintenance problems. He used his knowledge and experience to extend the service life of the petroleum coke mill from 6 months to 17 months. He also found a way to solve the problem of large-scale induced draft fan maintenance through continuous tests. "The craftsman spirit is not only the technology itself, but also needs to continue to innovate. Only by tireless pursuit of overhaul technology can the diagnosis, overhaul and maintenance of equipment be perfect, this technology can be better inherited, and the spirit of hard work can be better carried forward."
