Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional A572 grade 50 ms steel coil production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of A572 grade 50 ms steel coil leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled A572 grade 50 ms steel coil products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the A572 grade 50 ms steel coil rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our A572 grade 50 ms steel coil quality. Till now, we keep exporting around 100 tons per month as regularly.
For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The A572 grade 50 ms steel coil, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.
The company revolves around the long-term strategy of "building a quality base and building a century-long BEBON", adheres to the development ideas of innovation, transformation, and improvement, vigorously promotes transformation and upgrading, structural adjustment, energy conservation and emission reduction, and strives to create high-quality steel with strong core competitiveness and distinctive features The production base has become a green steel city with intensive land use, clean production, efficient use of resources, harmonious and friendly production and environment, business and society, and BEBON characteristics.
