一、带钢平整的任务冷轧带钢车间在生产深冲带钢时,在其最终退火后都要给予较少的冷轧道次。根据钢种和不同的用途,其平整延伸率约在0.3-2.0％之间。通常,平整是在特殊机架上进行的。平整的目的: a)消除钢材的滑移线; b)得到所要求的表面性能; c)消除带钢的机械应力并得到平直的带钢。从众多的出版资料中得知,深冲带钢用很小的变形量平均时,随着屈服平台的缩短,屈服点下降。在某一平整延伸率下,屈服点降到最低值,大的变形量会引起屈服值
First, the task of strip formation Cold-rolled strip plant in the production of deep-drawn strip, after its final annealing should be given less cold rolling pass. According to the type of steel and different uses, the flat elongation of about 0.3-2.0%. Normally, leveling is done on a special rack. The purpose of leveling is to: a) eliminate the slip line of the steel; b) obtain the required surface properties; c) eliminate the mechanical stress on the strip and obtain a flat strip. From a large number of published information that deep drawing of steel with a small deformation on average, with the yield platform shortening, yield point down. At a certain level of elongation, yield point down to a minimum, a large amount of deformation will lead to yield value
