The project has achieved a breakthrough in core technology of high-end wide-width stainless steel hot rolling production line process and equipment from scratch, and independently designed and manufactured the world's widest Liyang Delong 2680mm stainless steel hot rolling production line. 

Its innovation achievements are as follows: 

1.Created the first "1+8" wide stainless steel hot rolling production line process configuration,  developed high-precision distribution strategy, temperature model, force and energy model,  constructed the whole process simulation analysis system and process optimization technology, and realized multi-variety, multi-specification stainless steel hot rolling products efficient and stable production and thickness and width limit breakthrough.

2.Developed a new type of finishing mill work roll bending and transverse rolling device, and realized the independent design and development of complete equipment of wide-width stainless steel thin strip hot strip rolling and green application demonstration.

3.Developed a stainless steel hot rolling production line and process parameter design software that integrates mechanism model, production data and deep learning algorithm, and developed a roll shape curve design optimization system，and realized the overall layout, equipment configuration, parameter optimization and other digital and intelligent control of the hot rolling production line.

After identification, the overall technology of the project has reached the international advanced level, and it has reached the international leading level in the "1+8" hot continuous rolling process technology, work roll bending and traversing device and plate shape control.Results successfully applied to 8 stainless steel production lines such as Liyang Delong and Dingxin Indonesia, occupying more than 90% of the domestic similar equipment market.
