en.Wedoany.com Reported - The automation upgrade project at the smelting workshop of Xinjiang Nonferrous Metals Group's Kalatongke Company in China was successfully completed on May 20, with the production line smoothly undergoing a commissioning trial run. This automation upgrade project commenced after the smelting furnace was shut down on April 25, leaving a construction window of only 20 days.
The upgraded central control room now enables centralized monitoring and management of production conditions, allowing staff to remotely monitor equipment operating parameters across various production stages via mouse control. The new automated production model has reduced operational intensity. Key positions in the smelting workshop, including the acid plant, oxygen generation station, converter, return water station, and waste heat boiler, have all achieved centralized intelligent equipment control.
At the beginning of the year, Kalatongke Company made overall plans for the intelligent upgrade of the smelting workshop. Leveraging the Chen Kehai Model Worker Innovation Studio, it formed a technical cooperation alliance with Jinchuan Group Information and Automation Engineering Co., Ltd. The upgrade scope included DCS system integration, PLC system upgrades, instrument renewal, network optimization, and the removal and replacement of outdated power distribution cabinets. The project team divided the work into six major operational zones, including the feeding area, side furnace area, and converter area, simultaneously advancing tasks such as wiring, programming, signal detection, and equipment disassembly and installation.
During the construction period, electromagnetic clutter and high-temperature vibrations generated by multi-trade crossover operations interfered with automated signal transmission, causing debugging work to stall multiple times. Qu Yanqiang, an engineer from Jinchuan Information Automation Company, pointed out that the on-site electrical wiring had undergone multiple modifications, resulting in discrepancies between the actual line models and the standard drawings, with inconsistent and disorderly connection methods. During the debugging phase, a sudden signal loss fault occurred in the frequency converter at the fan room. Technical leaders from both sides remained on-site to conduct item-by-item troubleshooting. Li Delin led a team to inspect each frequency converter, meticulously tracing every single line, and spent two days locating the wiring error point. Chen Yuxin verified terminal blocks, cables, and signal interfaces one by one within the confined space of the fan room. The project team completed the automation upgrade task within the 20-day construction period, making the production line ready for material feeding and production resumption. The new, fully localized control system offers simpler operation, more stable signals, and more comprehensive protection.
