Production Practice of Acid-free Pickling 82B Wire Rod in Bagang
Surface defect is an important index affecting the quality of high-speed wire products,and it is the key factor of qual-ity control for hard wire products.Due to the influence of material shape,groove surface and pass shape,the surface of rolled parts is damaged in the process of deformation,resulting in surface defects such as cracks,marking and skin warping,resulting in quality objection.In this paper,the deformation of rolled parts in the whole rolling process is tracked and the causes of sur-face defects of hard wire steel are analyzed.The surface defects of hard wire steel were solved and the quality of hard wire steel products was improved by optimizing the hole shape and production process.
