LR grade A shipbuilding steel plates,The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.

The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the steel plate.
