Recently, Shanxi Jianlong's 1500mm coil production line completed the trial rolling of the new low-alloy high-strength steel Q460C-L for cold rolling. After testing, the core data of the trial rolled coil, such as yield strength, tensile strength, and elongation, all met the standards, and the surface quality and dimensional tolerance control were better than expected.
This not only marks an important breakthrough for the company in the research and development and production of high-strength steel, but also injects strong new momentum into further optimizing product structure and enhancing market competitiveness.
As a high-strength structural steel, Q460C-L has the advantages of high strength, good welding performance and corrosion resistance. It is widely used in building structures, bridge construction, vehicle manufacturing, engineering machinery and other fields.
This product has extremely stringent requirements on rolling process control and product quality consistency. To ensure the smooth progress of the trial rolling, Shanxi Jianlong quickly formed a cross-departmental technical research team, bringing together technical backbones in core areas such as rolling technology, quality control, and equipment maintenance.
During the trial rolling preparation stage, the research team comprehensively sorted out the rolling process data of similar steel grades at home and abroad, closely combined with the existing production line equipment conditions, and completed multiple rounds of parameter simulation and solution demonstration. During rolling, operators strictly follow standardized operations, and production data from the entire line is collected and fully recorded in real time, laying a solid data foundation for subsequent process traceability and parameter optimization. In the future, Shanxi Jianlong will continue to deepen collaborative innovation between industry, academia and research, continuously increase investment in the research and development of new products, new processes and new technologies, strengthen refined management of the entire process, and continuously improve product quality stability and brand influence. At the same time, the company will also actively promote the research and development and layout of more high-performance, high-value-added strategic new products, providing solid support for the company to achieve higher quality and more sustainable development.
