New type of public processing elements for packaging steel strips

1) Under the existing production process conditions, by adding carbon and adding Nb and other alloys to improve the strength of the steel on the basis of the company’s conventional packaging steel strip, it can produce high-quality steel that meets the requirements of the YB/T025-2002 standard. Strength packing tape.
　　2) 900MPa steel is brought into the strong fixed nitrogen element niobium, the free nitrogen in the steel tends to '0
　　3) Under the current production process, the packaging steel strip can obtain different required mechanical properties at different annealing temperatures, and can meet the requirements of different users for different levels of blue ribbons.
　　4) The current rolling process has a certain impact on the performance of the strip steel. It is necessary to ensure the heating temperature and heating time to ensure the full melting of niobium, while reducing the initial and final rolling temperatures to improve the solid-melt strengthening effect of niobium. To further refine the grains, ferroniobium microalloying should be combined with the development of ultra-fine grained steel to strengthen the strengthening and toughening effect of Nb on steel to achieve the purpose of increasing strength and plasticity. In addition, it can be increased by cold rolling. The thickness dimension of the incoming strip steel, thereby increasing the degree of deformation of the cold-rolled strip steel to increase the strength of the bluish strip.
　　5) The newly developed packaging steel belt products are advanced and creative. The invention and application of new steel grades can broaden the field of new materials and develop new products with higher performance requirements. The development and application is the first in Egang, and it has laid a good foundation for the next development of higher grade steel grades and higher quality blue ribbons.
