[SMM Analysis] Yangjiang Hongwang 700000 ton Cold Rolling Project promotes the Transformation of domestic Manufacturing Industry through the Operation of "Black Light Factory" Internet + Manufacturing

SMM10, March 29: recently, in Hongwang stainless steel cold rolling workshop, 746m long production line is running in an orderly manner. Calendering, annealing, pickling, leveling, within a few minutes, a coil of steel coil plate with the original thickness of 3.0 mm is rolled into a coil of about 0.8 mm. These coils will be widely used in the production of stainless steel related products. Due to advanced equipment and smooth trial production, the first phase of Hongwang project is expected to achieve the processing target of 700000 tons of high quality stainless steel cold rolled sheet per year. After reaching full production, the annual output value is about 10 billion yuan. However, it is such a big project that requires very few production workers. The "black light factory" is the wisdom factory, because it does not need to be operated manually, so it can turn off the lights and run, so it is named after it. The first phase of Hongwang stainless steel cold rolling project, which has just been put into production, is a "black light factory" planned and built with the goal of wisdom factory.

Zhu Jiqiao, chairman of Yangjiang Hongwang Industrial Co., Ltd., said: we have added a lot of intelligent equipment, including automatic packing, automatic unpacking and automatic driving. We used to need people to do it, but now we all do it mechanically. We leave the previous industrial data to the system to do it on its own, without the need for people. There are two people at the moment. According to the person in charge of the enterprise, the project adopts industry-leading multi-roll continuous rolling technology and intelligent electronic control technology, which can upgrade the cold rolling process such as continuous rolling, continuous retreating and pickling to the whole process of automatic production. This can not only improve the production efficiency, but also ensure the stability of product quality. At present, the construction of Hongwang Phase II and Phase III projects has also been officially launched. According to the plan, the second phase adopts black leather through two stands, with an estimated annual output of 500000 tons, and the third phase adopts two reversible 20-high cold rolling mills and continuous annealing pickling line units, with an estimated annual output of 300000 tons of thin sheet. The two phases of the project are also aimed at the "black light factory" as the goal of planning and construction. Yangjiang Hongwang Industrial Co., Ltd. Chairman Zhu Jiqiao: human control has emotion, equipment does not, its memory function is more powerful, self-learning function is more powerful, we can now through the accumulation of data, we can get reliable, stable quality, to provide customers with better quality. In terms of thickness (error), we can control it at 0.001 mm.

According to SMM, Hongwang's 700000-ton cold rolling project in Yangjiang has greatly improved its production efficiency through the operation of the "Black Light Factory". In addition, it has been able to ensure the improvement of quality in the production and management of products. In fact, the operation of the "black light factory" also marks the innovation of the domestic industry 4.0. it aims to enhance the intelligent level of the manufacturing industry, establish an intelligent factory with adaptability and resource efficiency, integrate customers and business partners in the business process and value of the steel industry chain, and finally achieve a rapid and effective product supply. Therefore, Hongwang Innovation to create "Internet + Manufacturing" will effectively promote the transformation of the domestic manufacturing industry.

A grand event for thousands of people in China's non-ferrous metal industry

Shanghai colored net (SMM) annual meeting is the annual event of the metal industry, with an annual participation scale of thousands of people, domestic and foreign metal industry people gathered together to review and summarize the experience and harvest of the year, and lay the groundwork for the production, operation and operation of the coming year.

This year's "2019 China Nonferrous Metals Industry Annual meeting and 2020 (SMM) Metal Price Forecast Conference" was jointly created by SMM and China Renewable Resources Industry Technology Innovation Strategic Alliance and Shanghai Nonferrous Metals Industry Association. At the same time, the first "China Renewable Metals Industry chain Development Summit Forum" was held, and SMM metal price forecasting conference and waste battery recycling exchange were set up for you to enjoy. From the development of non-ferrous metal market to the recycling of renewable resources, from the detailed explanation of policies and systems to the research and development of industrial chain technology.

This is not only a meeting, but also an industry exchange of information, collision thinking sparks of brainstorming!
