1500mm wide strip successfully rolled at one time by China Metal Group Co., Ltd

July 26, 2012

In the face of severe industry competition, China Metal Group Co., Ltd has implemented the deep limit cost reduction, it has also explored the internal potential and explored the research and development of limit specification products. After breaking the design limit of 1430mm wide strip, it has recently refreshed the product width limit again, achieving a successful rolling of 1500mm wide strip at one time, making new breakthroughs in product specifications and leading the similar production lines in the same industry in China.

The width thickness ratio of 1500mm wide strip steel has reached the production limit, which is not only a test of the equipment's ultimate capacity, but also a challenge to the production process. The department actively organized management and technical personnel of process technology, equipment management, model control, etc. to hold a special meeting, systematically checked the limit positions of the whole process that affect the width production, sorted out the bottlenecks of the process, equipment, and model control for the production of ultra wide strip steel, took a series of measures such as adjusting the limit of tapping position, developing the negative width rolling width model, optimizing the guide margin and short stroke of roughing, finishing, and coiling processes, Ensure that the product achieves the expected production effect. Achieve 100% qualification rate of product width accuracy, temperature accuracy, side bending shape and other key indicators, laying a foundation for the expansion of varieties and specifications of China Metal Group Co., Ltd 1580 hot rolling production line.
