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

Packaging steel strip manufacturer of cold rolled steel strip on the performance and the influence of the hind leg processing despite the cold rolling mill is mainly used to get the requirements of the rolled piece actual size, but if we don't change the deformation of the surface of the metal actual state and metallurgical conditions, cold rolling will not be able to achieve the above purpose. Strip in rolling, the surface is usually carries Zu rolling lubricant residues, the strip surface is dirty, and occur when 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, ask its surface is very clean, so you must to remove all residual rolling lubricant from the strip surface. At the same time, in order to restore the required metallurgical properties, strip heat treatment must be conducted. As will be seen, however, the dynamics of the heat treatment process for steel strip the influence of pressure ratio, and even after heat treatment, cold rolled down rates in strip anisotropic characteristics and its influence is still evident texture. Brief introduction 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.
