Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the S275J0, S275J2 hot rolled plate project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of S275J0, S275J2 hot rolled plate customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel S275J0, S275J2 hot rolled plate produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.
