Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This A709 grade 100 bridge steel plate method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.
BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.
Hot rolling and cold rolling are all the processes of forming steel plates or profiles, which have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is usually used to produce small size steel and thin plate. With the development of new technologies such as the precision of hot rolling size, shape and surface quality and the continuous emergence of new products, A709 grade 100 bridge steel plate, hot rolled steel strip and steel plate are widely used and have more and more competitive strength in the market.
In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product A709 grade 100 bridge steel plate structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel A709 grade 100 bridge steel plate supplier in the world.
