What are the characteristics of medium and thick plate, A588 grade B HSLA steel plate? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, A588 grade B HSLA steel plate is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous A588 grade B HSLA steel plate process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.
The company always adheres to the concept of green production, follows the development path of innovation, transformation and improvement, and has carried out in-depth cooperation with Zhengzhou University and other scientific research institutes, planning from a high starting point, strict standard design, and successfully implementing engineering projects With nearly 20 research and development projects, the company's production technology and equipment are at the forefront of the industry, and indicators such as environmental protection, energy consumption, cost, and resource utilization have reached the advanced level in the industry.
