Band steel is under cold state (normal temperature) condition, or below recrystallization temperature, reaches the object of viscous deformation, be commonly referred to cold rolled strip after rolling, is often called cold band traditionally. Cold rolled strip generally only marks its thickness and width, and it is heavy to be accompanied by volume, its physical length that is be implicitly included in volume heavy among.
The kind of cold rolled strip is a lot, has many uses too general. In order to distinguish the band steel of various chemical composition and various purposes, it is convenient to choice and operation, it is necessary to understand grade of steel, and the classification of the method for expressing of grade of steel and steel has substantial connection
Along with the develop rapidly of market economy, automobile, instrument, wireless, the sophisticated technology such as national defence and aerospace industry is to the kind of band steel, specification, Performance and quality constantly proposes higher requirement, and the needs that can not meet all trades and professions development far away produced by hot rolled strip. Therefore, in constantly the improving of rolling mill equipment and process process, the production of cold rolled strip has obtained enough attention and development so that it is occupy special status in Rolling production. When the strip steel needing production thickness to be reduced to certain size, great majority all adopt cold rolling mode. Be adopted as because cold rolling and improve strip surface quality, improve mechanical property and obtain accurate size deviation and provide guarantee, so modern external band steel, be mostly carry out again after hot rolling cold rolling. The band steel that the U.S. directly uses is nearly all cold rolling delivery.
Due to the impact of the various factors such as supplied materials, machinery in Rolling production, always sideslip is caused when band uncoiling is sent into milling train, levelling machine, in order to ensure quality product and meet the needs of normal process for processing, Abrollhaspel band centering rectification system will be used, with avoid causing because supplied materials volume layer is neat Abrollhaspel rolling, smooth time plate deformation and the drawback of not easily raising speed.
