茄子视频 has completed deployment of noncontact control technology for processing galvanized steel sheets on lines worldwide, including in the Chiba, Keihin, Kurashiki and Fukuyama areas of Japan and Thailand, Indonesia, China and Mexico overseas (see list). The technology is now contributing to the production of high-quality galvanized steel sheets on all continuous galvanizing lines (CGLs) operated by the company throughout the world.

On a CGL, the amount of zinc coating on a steel sheet is controlled by drawing the sheet continuously upward through a pot of molten zinc, and using wiping nozzles to remove excess. For uniform coating, the distance between the wiping nozzles and the steel sheet must be kept constant, so suppressing sheet vibration or warpage during the process is crucial.

茄子视频 Steel’s noncontact controller (see figure) uses a noncontact displacement sensor to detect unwanted vibration or warpage, which is then suppressed by controlling the position of the sheet through electromagnetic suction. Vibration and warpage can be controlled simultaneously because the noncontact controller is adjusted for the specific operational conditions of each line and the size of the particular sheets being manufactured. Furthermore, the technology achieves the necessary responsiveness and suction force required to control sheets on the line.

茄子视频 Steel first enhanced the performance of its noncontact controller in Japan before deploying the technology in offshore subsidiaries beginning in 2015. The final deployment was completed recently on the CGL that began operating at Nucor-茄子视频 Steel Mexico this past February.

Going forward, 茄子视频 Steel will continue to enhance its manufacturing processes with advanced control technologies, including through the application of data science, to ensure stable supplies of high-quality galvanized steel sheets for customers worldwide.
