On the morning of March 31, the first ultra-thin strip industrialized production conference in China came with an inspiring news: China's first, the world's most advanced twin-roll strip casting and rolling technology to achieve industrialized production. This technology is the first domestic ultra-thin steel strip production line successfully constructed by SGJT by introducing the American Nucor ultra-thin ribbon CASTRIP technology and combining independent innovation.
SGJT Group and Nucor Steel held a signing ceremony for the performance assessment and acceptance of the Shagang ultra-thin strip project. The signing of Shen Wenrong, Chairman of SGJT Group's Board of Directors, and John Ferriola, Chairman of Nucor Iron & Steel, signified that the performance of the ultra-thin strip project had reached its intended goal.
This time, SGJT cooperated with Nucor and MCC Jingcheng of the United States to successfully achieve industrialized production by adopting the double-roll ultra-thin strip casting and rolling technology. The steel production technology, especially the thin strip production process change, has a huge driving force and an important impact.
This is a technological feast for sharing and win-win
SGJT will rely on the first-class scientific research team and production technical personnel to pioneer and innovate, and continuously improve the product quality and index level of ultra-thin hot-roll products, and provide the most reliable products, the most affordable prices, and the most thoughtful services for the majority of downstream users. Achieve win-win cooperation between the two parties. At the same time, with the successful experience of the first production line, in line with the principles of technology sharing and promoting technology applications, we are looking for partners throughout the country to jointly promote China's ultra-thin strip technology application, production line construction and product promotion, and continue to promote China's steel industry. Progress and innovation of metallurgical production technology.
The advantage of ultra-thin strip technology is that it can produce ultra-thin, ultra-wide high-strength steel and special steel very efficiently, and the product performance is stable, the fluctuation between batches is small, and the fluctuation of yield strength and tensile strength between different batches is significantly lower For traditional hot continuous rolling.
Frank Fisher delivered a speech and pointed out that Shagang has set multiple production records on this CASTRIP ultra-thin strip production line, including daily, weekly and monthly production records, setting new standards for existing and future plants . Expert teams from various cultures around the world have jointly launched the pioneer of twin-roller casting and rolling technology. The close cooperation between the various teams to accelerate the development of new products will surely bring product applications into new fields and continue to change the world.
The project began preparations in January 2015 and lasted four years and three months. It has now officially entered industrial production, which will generate structural innovations, process changes, and energy saving and emission reduction for ultra-thin strip products in SGJT and even Chinese steel companies. Active demonstration of radiation effects. As of the end of March 2019, the production line has produced over 200,000 tons of ultra-thin ribbons, and the products after trimming and straightening have basically achieved a balance of production and sales. Products cover shelves, automobiles, agricultural machinery, containers, saw blades and many other fields.
