On March 13, the 14th China Cement Industry Summit and TOP100 Award Ceremony Technology Special Event sponsored by China Cement Network was held in Hangzhou, Zhejiang Province. Su Tao, general manager of Wuxi Jinhua, made the theme report of "Intelligent Digital Wear-resistant Surfacing of Roller Press Vertical Mill".
Su Tao believes that the following problems may exist in the outsourcing of roller press vertical mill in the cement industry:
Quality: The technical level of the outsourcer is uneven, which may not meet the quality requirements of the cement plant for the repair and maintenance of the roller press, such as the flatness and wear resistance of the repaired roller surface are not up to the standard. As a result, the equipment operation is unstable and the material extrusion effect is poor. In order to reduce the cost, the outsourcer may use inferior wear-resistant welding wire, which will affect the overall performance and service life of the roller press.
Time: When there are obstacles in communication and coordination, the outsourcer may not be able to respond to the maintenance needs of the cement plant in a timely manner, resulting in prolonged equipment downtime and affecting the production schedule. If the outsourcer undertakes multiple projects at the same time, there may be problems in resource allocation, and the maintenance work of the roller press can not be completed on time.
Cost: In addition to direct outsourcing costs, there may also be additional costs arising from communication, management, etc. If the terms of the contract are not clear, the outsourcer may increase the cost for various reasons, such as additional charges for "new problems" found in the maintenance process.
Wuxi Jinhua has developed a JH-1280 digital surfacing workstation, which can remotely monitor and adjust various welding parameters on site, such as welding current, welding voltage, rod speed, skip shift distance and other parameters. On-site operators do not need professional personnel, thus greatly reducing labor costs. This surfacing workstation is connected to the Internet. Enterprise leaders can also monitor the operation of the equipment through remote mobile APP and computer software. It can also record and store various welding parameters and operation data at the surfacing site. In case of quality problems in the surfacing process, the data can be called for analysis. The consumable intelligent management and control system
of JH-1280 digital surfacing workstation uses advanced algorithms to accurately predict the consumption of welding wire. The algorithm combines multi-dimensional information such as equipment operation data, welding process parameters and historical consumption records, and achieves accurate prediction of welding wire consumption through large data analysis and machine learning technology. Taking a cement plant as an example, before using the prediction algorithm, the inventory management of welding wire was chaotic, and the situation of inventory backlog or shortage often occurred. After use, the prediction accuracy is as high as 98%, which effectively avoids unnecessary inventory waste.
