Packaging steel strip of new public processing elements

1) Under the condition of the existing production process, through regular packaging steel strip in the company on the basis of carburization and join the Nb micro alloy strengthening to improve the strength of the steel alloy, can meet the YB/T025 - producing 2002 in the standard requirement of high strength packing belt. 2) 900 mpa steel into the strong fixed nitrogen niobium, free nitrogen in steel to & other; 0' For non strain aging steel. 3) Under the current production process, packaging steel strip under different annealing temperature, the access to different requirements of mechanical performance, can meet the requirements of different users for different level blue belt. 4) The present rolling technology, has a certain influence on the performance of the steel strip, to ensure the heating temperature and heating time, ensure full melting of niobium at the same time reduce the early, finishing temperature, improve the reinforcement of niobium solid melts, further refine grain, niobium microalloyed iron should be combined with the development of the ultrafine grain steel, strengthen the Nb on the toughness of steel, to improve the strength at the same time, enhance the purpose of the plastic, the other can increase the thickness of cold rolled strip steel material size, thereby increasing cold-rolled strip deformation degree to improve the strength of the blue belt. 5) Newly developed packaging steel strip to be advanced, creative products, the invention and application of new steel grade, can broaden the field of new materials, and then develop higher performance requirements of the new product, the development and application of strip steel blue in EGang is initiative, and develop a higher level for the next step of steel grade and higher quality of blue belt laid a good foundation.
