Recently, the first batch of steel plates with high technical difficulty, high performance and high value-added large thickness bridges produced by Wugang Company of HBIS Group were delivered to customers as scheduled, and will be used in the manufacture of cable saddles at the core load-bearing part of the Zhangjinggao Yangtze River Bridge, the world's largest span suspension ———bridge.
Because the Zhangjinggao Yangtze River Bridge adopts a number of new technologies to fill the gaps at home and abroad, its requirements for steel materials in the core load-bearing parts are particularly strict. In the process of in-depth docking with the market and connecting with customers, Wugang tailors high-end extra-thick bridge steel for them according to the individual needs of customers to fully meet their special requirements. In the production process, in view of the technical problems such as the thickness of the steel plate is 330mm, which has exceeded the national standard, and the impact toughness index has reached the world-class requirements, Wugang has set up a research group with high-end and high-efficiency product research team members as the main force, and the linkage of various factories and departments to innovate the smelting process, optimize the composition design, effectively improve the internal quality of the ingot billet, and ensure that it can meet the requirements of the national standard for first-class flaw detection; In the rolling process, we strictly implement rolling control and cooling control measures, and overcome world-class problems such as the impact of this kind of super-thick steel plate on impact performance in one fell swoop, ensuring that the trial steel plate is delivered to customers quickly and with high quality. After the inspection, the customer reported that the performance was good, and expressed high appreciation for Wugang for creating the first thickness of this type of steel plate in China, and the performance indicators reaching the international leading level.
As a "bridge of science and technology, a bridge of innovation", the Zhangjinggao Yangtze River Bridge has made the "China Bridge" break through the 2,000-meter span mark for the first time, continuously making breakthroughs in new structures and new processes, filling a number of technical gaps at home and abroad, demonstrating "Made in China" and "Created in China" in the world, and greatly enhancing the global influence of China's bridge brand.
As a key cross-river channel project during the national "14th Five-Year Plan" period, the construction of Zhangjinggao Bridge is of great significance for the implementation of the national strategy for the integrated development of the Yangtze River Delta and the development of the Yangtze River Economic Belt, optimizing the layout of the Yangtze River trunk cross-river channel, improving the layout of the regional road network, promoting the integrated development of cross-river and building a high-level Yangtze River urban agglomeration
