Boiler vessel plate: it is used to manufacture various boilers and important accessories. Because the boiler steel plate is in the medium temperature (below 350 ° C) and high pressure state, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and air corrosion. SM490YB carbon steel plate sheet. It is required to ensure a certain strength and good welding and cold bending performance. It is a special steel plate for pressure vessel, which is widely used in China.

The wear-resistant layer of SM490YB carbon steel plate sheet wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy SM490YB carbon steel plate sheet carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

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 SM490YB carbon steel plate sheet 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 SM490YB carbon steel plate sheet steel plate.
