Low welding crack sensitivity high-strength steel plate, today mainly introduces Q620CF, with three grades C, D, E. The grades of low-welding crack sensitivity high-strength steel plate: Q460CFC, Q460CFD, Q460CFE, Q500CFC, Q500CFD, Q500CFE, Q550CFC, Q550CFD , Q550CFE, Q620CFC, Q620CFD, Q620CFE, Q690CFC, Q690CFD, Q690CFE, RE 32 low alloy steel ship plate, Q800CFE. It is mainly used for the production of hydropower penstocks, construction machinery, railway vehicles, bridges, high-rise and large-span buildings that require high weldability.
Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the RE 32 low alloy steel ship plate alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the RE 32 low alloy steel ship plate wear-resistant property to meet the requirements of specific working conditions.
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 RE 32 low alloy steel ship plate 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 RE 32 low alloy steel ship plate steel plate.
Keep close relationship with all manufacturers and users, cooperate sincerely, share weal and woe together. We are deeply tolerant of travelling with you! We value and value each other's career and friendship. No matter when and where, all our staff will spare no effort to put into the work, and do their best to provide RE 32 low alloy steel ship plate satisfactory services for all friends, so as to achieve win-win and multi win for each other.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
