The company has absorbed the tension leveler roller cassette technology from foreign companies such as SIEMENS, VAI, DANIELI, SMS, SUNDWIG, STAMCO, and Mitsubishi Hitachi, and developed a series of high-precision roller boxes.These not only complement the tension levelers, scale breaker, and other equipment independently developed by the company and applied in the steel and aluminum processing industries, but also meet the needs of replacing spare parts for foreign equipment introduced into the domestic steel and aluminum processing industries.
