then the explosion of the process of the composite and hot-rolled composite panels characteristics of how? Let me talk about the explosion of composite features: an explosive compound is cold, therefore it can be generated in addition to a variety of other than stainless steel composite plate of metal composite panels, such as titanium, copper, aluminum, and so on. Second, the explosive compound production of stainless steel clad plate thickness can reach several hundred mm thick stainless steel clad plate, as some large base and tube sheet, etc. But not suitable for production of the total thickness of less than 10 mm thin composite steel plate. Three explosive compound of the energy production of explosives, the environment will cause vibration, noise and dust pollution. Less investment in equipment, there are hundreds of domestic explosion of plant size. Lower explosive compound production efficiency due to the limitations of weather and other conditions. Say hot-rolled composite process characteristics: First, the use of large-scale plate rolling mill and hot strip mill production, high production efficiency, delivery speed. Products, large format, the thickness of the free combination. Stainless steel cladding thickness of 0World Steel Pipe .5mm or more can produce. Investment, less of the manufacturer. Second, due to the rolling compression ratio limit, hot-rolled production is not yet the production of composite steel plate thickness of 50mm or more, does not facilitate the production of small batch, round shape of the composite board. The advantages of hot-rolled composite panels 6, 8 World Steel Pipe News , 10 mm thin gauge composite panels. Hot-rolling conditions, the production of composite coil, lower production costs, to meet user needs. Third, in the current technical conditions, the hot rolling process can not be directly producing titanium, copper, aluminum and other non-ferrous metal composite panels. In summary, two distinct production process, while the existence and development to meet the needs of different users vary widely. The explosion rolling method is a combination of the above two processes, not repeat them.
Stainless steel composite board combines the characteristics of a variety of carbon steel and stainless steel, with its excellent performance and low cost for users welcomed the broad market prospects. Interestingly, from the fifties, after the development process of more than half a century of ups and downs, there are still a lot of people do not know it. More people have not used it. It should be said that the stainless steel clad plate market is far into the process of maturity, still in development. Science and technology workers for the exploration and hard work of building a resource saving society will never stop.
Stainless steel clad plate is a steel plate of carbon steel primary and stainless steel cladding combination of composite panels. Its main feature is the carbon steel and stainless steel to form a solid metallurgical bond. Pressing, bending, cutting, welding and other processing can be a good process performance. The base material of stainless steel clad plate Q235B, 16MnR, 20R ordinary carbon steel and special steel. The cladding material can use the various grades of stainless steel 304,316 L, 1Cr13 and duplex stainless steel, etc.. Material and thickness can be freely combined to meet the needs of different users. Stainless steel clad plate has been widely used in petroleum, chemical, salt, water, electricity and other industries. Stainless steel clad plate as a resource for savings-type products, to reduce the consumption of precious metals, a significant reduction in project cost. To achieve low cost and high performance with good social benefits.
Stainless steel clad plate is produced? Industrial production of stainless steel composite panels There are two main ways, explosive compound and hot-rolled composite. The explosion clad plate production process is overlapping stainless steel plate placed on the carbon steel substrate, the mat interval between stainless steel and carbon steel substrate to a certain distance. Stainless steel tile on top of explosives, the detonation of an explosive energy, high-speed impact of carbon steel substrate, resulting in the high temperature and pressure so that the interface of two materials to achieve solid phase welding stainless steel plate. Ideally, per square millimeter of the interface shear strength of 400 MPa. Hot-rolled composite plate technology is based on the carbon steel substrate and stainless steel plate in the physical pure state from rolling under high vacuum conditions. The spread of the two metals in the rolling process to achieve full metallurgical bonding. Of course, in order to improve the wetting of the composite interface, to improve the bonding strength, physical and chemical treatment of the interface we have to take a series of technical measures. These two kinds of composite board manufacturing methods are the execution GB/T-8165-1977 national standards. The standard non-equivalent to the standard the Japanese JISG3601-1990, the major technical indicators are the same or higher than Japanese standards.
