Today (March 31) morning held in China's first ultra-thin strip industrial production release, shagang group officially announced: China's first, the world's third, the world's most advanced double-roll thin strip casting and rolling technology to achieve industrial production.This technology is the first industrial ultra-thin belt production line successfully built by shagang through the introduction of nucor ultra-thin belt CASTRIP technology and independent innovation.


Zhang jiagang party secretary shen guofang, vice mayor lu chongmin attended the press conference.Zhao zhongkang, director of the committee of experts on the evaluation of scientific and technological achievements of the iot and sensor alliance of the Ministry of Industry and Information Technology, lu wenyan, deputy secretary-general of China iron and steel industry association and President of China metallurgical press, as well as nearly 200 representatives from Xinhua News Agency, xinhuanet, China metallurgical news, world metal guide, xinhua daily, suzhou daily and other media attended the meeting.


At the meeting, shagang group and nucor steel company held the signing ceremony of shagang ultra-thin belt project performance assessment and acceptance.Shen wenrong, chairman of shagang group, and John ferriola, chairman of nucor iron & steel signed on behalf of the two sides, marking the performance of the ultra-thin belt project to reach the target.


Shen guofang said that over the past 40 years, under the leadership of comrade shen wenrong, shagang people have been adhering to the enterprise spirit of "self-reliance, hard work, innovation and continuous climbing", deeply rooted in the main industry of iron and steel, overcoming all difficulties and forging ahead, becoming one of the "world top 500" for ten consecutive years, and writing a miracle of China's private iron and steel enterprises.This time, shagang group again with a large amount of money, big pattern, big boldness, to promote the first ultra-thin belt production line of industrial production, which is not only unique in China, in Asia is also unique.In the future, zhangjiagang has broad prospects and unlimited business opportunities. We warmly welcome friends at home and abroad to invest in zhangjiagang, share great opportunities and win a win-win future.


Jiang shangqing said that shagang out of a large scale of science and technology leading the construction of modern steel enterprises development road.The shagang nucor, China metallurgical Beijing sincere cooperation with the United States, with double roll ultrathin roll casting technology to achieve industrial production, is China's iron and steel iron and steel enterprise production process of technological innovation and a great attempt and successful practice, will China's steel production technology, especially the thin belt production process changes have a great and important role in promoting.


Shen bin said that shagang has been actively benchmarking international advanced technology, aiming at the forefront of the industry, adhering to the combination of introduction and absorption and independent innovation, constantly optimize the technical equipment and product structure, enhance the competitiveness of enterprises.He emphasized that shagang would make use of the successful experience of the first production line and seek for partners nationwide in line with the principle of technology sharing and technology application to jointly promote the application of China's ultra-thin belt technology, production line construction and product promotion, and continuously promote the progress and innovation of China's iron and steel metallurgy production technology.


How much is shagang thin strip production line?


Ultra-thin strip production technology is a new metallurgical frontier technology with the greatest development potential in today's iron and steel industry. It is also a new technology with short process, low energy consumption, low investment, low cost and green environmental protection, which has been invested by the world's major iron and steel enterprises.


To sum up, there are three salient features:


First, the process is short, less land.The production line length of conventional hot continuous rolling is about 800 meters, while that of ultra-thin strip is only about 50 meters.


Second, low energy consumption and low emissions.Some data show that the total energy consumption of the ultra-thin strip process is expected to be about 1/5 of the traditional hot continuous rolling process, and the carbon dioxide emission is expected to be about 1/4 of the traditional hot continuous rolling process.


Third, the rhythm is fast, stable performance.The advantages of ultra-thin strip technology lie in the ability to produce ultra-thin, ultra-wide high strength steel and special steel with very high efficiency. Moreover, the product performance is stable and the fluctuation between batches is small. The fluctuation of yield strength and tensile strength between different batches is significantly lower than that of traditional hot rolling.


It is reported that the project began to prepare in January 2015, lasted four years and three months, and now it has officially entered into industrial production, which will produce positive demonstration radiation effect for shagang and even Chinese iron and steel enterprises' ultra-thin belt product structure innovation, process change, energy saving and emission reduction.By the end of March 2019, the production line has produced over 200,000 tons of ultra-thin belts, and the products after trimming and straightening have basically achieved a balance between production and sales.Products involved shelves, automobiles, agricultural machinery, containers, saw blades and other fields.
