The process of hot rolling to produce stainless steel composite panels

The layered metal composite panel not only has the characteristics of the cladding material, including corrosion resistance, heat resistance, wear resistance, etc., but also has the characteristics of the base material, such as strength and stiffness. It is a new type of material. Among them, stainless steel composite panels are the most widely used among metal composite panels, accounting for more than 80%. It uses corrosion-resistant, heat-resistant, and wear-resistant stainless steel as the coating, and uses carbon steel or low-alloy steel with relatively high strength and good plasticity and toughness as the base layer. Its materials and thicknesses can be freely combined.

Compared with pure stainless steel, stainless steel composite plates have obvious performance and cost advantages. They can save 70 to 80% of alloying elements such as chromium and nickel, thereby saving 30 to 50% of costs. Not only do they greatly save stainless steel materials, but they can also significantly reduce the cost of various components. The material cost of equipment and structural parts. As a resource-saving product, it can be widely used in petroleum, chemical, salt, water conservancy and electricity and other industries, greatly reducing project costs, achieving the perfect combination of low cost and high performance, and has good economic benefits.
At present, the industrial production of stainless steel composite panels mainly adopts explosion cladding, explosion cladding rolling and rolling cladding processes. In China, stainless steel composite panels are mainly produced by explosion cladding and explosive clad rolling methods. However, with the development of science and technology, the requirements for composite materials are getting higher and higher, especially the enhancement of environmental awareness. The disadvantages of explosive composite have gradually attracted people's attention. First of all, the thickness range of the cladding used in the explosion process is limited, and good combination cannot be achieved if it is too thick or too thin; at the same time, its continuity is not strong, the degree of automation is low, and the efficiency is low. Work hardening occurs on the joint surface, so softening treatment is required after explosion. In addition, a specific explosion site is required. Although the explosion process has been widely used in developed countries such as the United States and Japan, the vibration and noise caused by the explosion are difficult to control. Since both the explosive composite method and the explosive composite rolling process have shortcomings, the industry is eager to develop a new type of rolling process. , efficient and environmentally friendly stainless steel composite panel production process.
In this context, domestic and foreign scholars have gradually turned their attention to rolled composite plate technology. As equipment develops in the direction of large-scale, high-speed, and continuous production, the hot rolling process can be used to produce various types of composite panels with high efficiency, high quality, and low cost. In particular, composite panels with a width exceeding 3000mm that cannot be produced by the explosion process can be produced. Significant advantages compared to explosion processes
