How to control the bending degree of TMCP NV E engineering ship steel during quenching

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 TMCP NV E engineering ship steel 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 TMCP NV E engineering ship steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the TMCP NV E engineering ship steel tensile strength is 490~620N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness that can be achieved at -40℃, -60 ℃.

The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced TMCP NV E engineering ship steel technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel TMCP NV E engineering ship steel production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.
