MEASURING SYSTEMS IN TUBE MILLS MEASURING SYSTEMS IN TUBE MILLS Surface Inspection surcon 3D Tube In tube production, surface defects are often perpetuated through the complete process chain. Non-stop surface inspection from billet to finished tube is therefore critical for the quality of the final product. With “surcon 3D Tube” surface inspection system, IMS provides tube manufacturers with another high-quality measurement tool. The system allows to detect surface defects at a much earlier stage in the rolling process than before, and to counteract them early and effectively by means of concrete corrective measures. In particular, the three-dimensional information about the spatial extent of the defects offers a far more reliable basis for deciding to what extent a surface defect can still be tolerated or whether immediate intervention in the manufacturing process is necessary. In addition, 100% surface inspection ensures that immediate knowledge is available as to whether a detected error occurs once, repeatedly on a tube or at the same length position from tube to tube - information that can be reliably determined is almost impossible by manual inspection. BENEFITS Automatic detection and classification of relevant defects and geometric data (including depth and position) Detection of defects ahead of further processing steps in the production cycle Continuous logging of all measuring data, product parameters and system events Archiving of data for process optimization Substitution of manual inspection Examples of defect type detection using surcon 3D tube surface inspection The exemplary types of defects shown here as examples for seamlessly rolled tubes are only a selection of concise samples of how they can be detected with the help of 3D surface inspection on finished tubes of different dimensions. Height profile of a defect in the form of a “shell” Depending on the error type, the cause of the error can be determined as quickly as possible and a corresponding countermeasure can be taken, e.g. a change of roll stands if all the following tubes were rolled out with the same significant defects in the case of a roll breakage or bearing damage.
