The scientific research on metal composite plates was first started abroad in 1860, and industrial production and processing originated in the 1930s. In fact, at the same time, the former Soviet Union also carried out basic scientific research on metal materials such as aluminum, tin, steel and metal-metal composites. Although Japan's research on metal composites is relatively late, it has developed rapidly and has become one of the countries with the largest research on metal composites in recent years. The research and development of metal composite plates in my country originated in the 1960s.
Explosive cladding method is used to produce and process metal composite plates, which uses the shock wave caused by the explosion to promote the cladding plate to move quickly to the base plate, while eliminating the gas in the gap, and at the same time using the collision to produce plastic deformation of the layered metal material on the contact interface , Melting and fusion, and then the metal plates are welded to each other, and the fusion interface of explosive composite type is wavy. There are many difficulties in the explosion method that are not easy to solve, which hinders the production, processing and product promotion of stainless steel composite thick steel plates. First of all, there are many limitations in the processing technology. This composite processing technology is basically difficult to implement a successful composite type for cladding and base steel plates with low plastic deformation and low deformation capacity, such as martensitic stainless steel cladding or austenitic carbon steel. . It is also difficult to overcome the bursting situation for the raw materials of the as-cast mechanism, such as rolled steel slabs. Secondly, because of the effect of "explosion window", the cladding is usually more than 3mm thick and the processing technology is relatively perfect with a plate width of less than 20 square meters. It is prepared for the manufacturing industry that requires thin cladding and large-format metal composite plates. Subject to huge restrictions. Finally, at present, the maximum width of 2 mm to 6 mm hot-rolled and hot-rolled steel strips of stainless steel casting manufacturers in the world is generally 2,000 mm. Affected by this, the width of the clad plate produced by the explosion method is limited, and the cladding plate After being pieced together, it is completely integrated with the base steel plate and still has a corresponding technical level. Finally, the combined explosion method belongs to the scope of the latest technology in terms of the principle of explosion mechanics, but it is only a low-efficiency manufacturing operation in terms of the actual explosion operation. In addition, from the perspective of investment and construction standards, the explosion method must be far away from urban areas, and no people or buildings are allowed within 5 and a half kilometers of the explosion central station. The storage and logistics of explosives and gunpowder are very strict. Require.
The advantage of the explosive cladding method is that it can achieve high-efficiency cladding of different metals without using complex processes such as high temperature or high pressure. In addition, since the lamination process is instantaneous, the contact area between the metal sheets is very large, resulting in a very strong bond.
With the deepening of research, the explosive composite method is not only used in the manufacture of metal composite plates, but also widely used in ceramic composite materials, polymer composite materials and other fields. So far, the explosive composite method is still an important composite material preparation method, which is widely used in aerospace, automobile, construction, military and other fields.
