Steel common defect types to reduce defect production methods

At present there are seven kinds of common defects: steel surface crack, scratch, scratch), folding, handle, scarring (lap) the burr, welding scar, end. Steel plant operators are the reasons causing common defects, defect in steel and processing methods have deep understanding, here is not introduced in detail. Focus on how to monitor the defect information.

For defect detection in a timely manner, the need for on-line detection, contour measurement instrument as online flaw detector is a good choice, it can detect most of the surface defects, folding, warping, pits, grooves, lugs, crack, scratch, scratch) such defects can be detected and displayed.

Profile measuring instrument is "attorney" steel surface quality monitoring. Rolling production, through an automated measuring instrument, the defect of the real-time monitoring, don't pass any defect, for now, it can detect the defect information of 0.5 mm and above, and is a comprehensive no dead Angle of the cross section test, to detect the frequency of 4000 hz, transverse longitudinal blind area is small, don't pass steel defects.

Contour instrument to monitor the quality of cross section through, then form a high-resolution display complete surface, allowing the detection of local and periodic surface defects, and the change of the size of the rolled products.

Profile measuring instrument to help in the process of producing steel strengthen production quality control, so as not to appear a lot of incomplete, affect the economic benefits of enterprises. It takes on steel surface defect, measurement analysis of the surface defects in production, and the defects of rolling technology and to explore the influence of performance, increase the use of steel properties and the yield.
