Packaging steel strip cold rolling steel strip on the performance and the influence of the hind leg processing

Packaging steel strip cold rolling steel strip on the performance and hind leg processing while the influence of cold rolling is mainly used to get the actual size of rolled piece requirements, but if we don't change the deformation of the surface of the metal actual state and metallurgical conditions, can not reach the mouth of the cold rolled. Strip in rolling, the surface is usually covered with the remains of the rolling lubricant, the strip surface is dirty, and sometimes directly due to the cold rolling on the rolling defects. More main is, as a result of the deformation, metal produced work hardening or improve the hardness, and reduce the ductility. Because the sheet or strip steel further processing or use of the electroplating tin, for example, requires very HaoJie table and must therefore be to remove all residual rolling lubricant from the strip surface. At the same time, in order to restore the play and the metallurgical properties of strip steel heat treatment must be conducted. As will be seen, however, these hot place deep in the process of dynamics affected by for strip steel pressure ratio, and even after heat treatment, cold rolled down rates in strip anisotropic characteristics and its influence is still evident texture. This dish will briefly introduce to the readers close dry tropical after a cold rolled plate with further processing of manufacturing steps. These steps include erase, heat treatment, leveling, secondary cold rolling, foil rolling, cutting, trimming and slitting, metals and organic coating, embossing, cold bending forming and oil, etc. This chapter will also discuss some metallurgy problems of these processes, including sections will also brief introduction of the electrical steel and stainless steel processing.
