Analysis and Control the Pressed into Defects of Acid Rolling Strip Foreign Body

There are two reasons to causes of defects of acid rolling line equipment and hot-rolled raw materials problems, so it is necessary to analyse the cold-rolled strip surface foreign body pressed into the defect microstructure and composition. It is found that this defect can be eliminated by improving the quality of the raw material, controlling strip shape, making reasonable squeezed roll transformation system, making the implementation of effective management of the full range of roll surface, carrying out the whole process of clean production, effectively controlling of the cold-rolled strip foreign body pressed into the generation of defects.
