The steel bar is rolled by a rolling mill and produces both surface defects and internal defects during the rolling process. The internal defect is that the original defects of the steel chain or billet are extended during the rolling process. These defects are mainly concentrated in the central part of the steel rod. The forms mainly include slag inclusion, shrinkage, delamination, and looseness. The amount of rolling deformation increases and increases. In actual production, these internal defects of the steel rod have a serious impact on the performance of the steel. For example, in steel rods used for forging, these internal defects will continue to exist inside the steel rod during the forging process, and some will continue to extend. Some will form a mezzanine. Therefore, the non-destructive testing of the internal defects of steel bars has attracted more and more attention. As one of the professional
bar surface defect detection machine manufacturers, Nanjing BKN provides high-quality ultrasonic steel bar testing equipment for you to choose. Feel free to contact us.
