The process of hot rolling production stainless steel composite board

The layered metal composite board has both the characteristics of overwriting materials, including corrosion resistance, heat resistance, wear resistance and other properties, but also the characteristics of grassroots materials, such as strength and stiffness, which is a new material. Among them, stainless steel composite boards are the most widely used in metal composite boards, accounting for more than 80%. It uses stainless steel with corrosion resistance, heat resistance, and abrasion resistance as the cover layer, while carbon steel or low -alloy steel with relatively high strength and better plastic toughness is used as the grassroots, and its material and thickness can be freely combined.

Compared with pure stainless steel, the stainless steel composite board has obvious performance and cost advantages, which can save 70-80%of alloy elements such as chromium and nickel, which can save costs 30 to 50%. Material cost of various equipment and structural parts. As a resource -saving product, it can be widely used in industries such as petroleum, chemical industry, salt, and water conservancy power. It greatly reduces engineering costs and achieves a perfect combination of low cost and high performance. It has good economic benefits.

At present, the industrial production of stainless steel composite boards mainly adopts explosive composite, explosive composite rolling and rolling composite technology. Domestic in China mainly produces stainless steel composite boards for explosive composite and explosive composite 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, and the disadvantages of explosive composite have gradually received people's attention. First of all, the thickness range of the complex layer of the explosion process is limited, and it is too thick and too thin to achieve a good combination. At the same time, its continuity is not strong, the degree of automation is low, and the efficiency is low. Machining hardening on the combined surface, so it is necessary to soften after the explosion. In addition, specific explosive places are needed. Although the explosion technology has been applied in large quantities in developed countries such as the United States and Japan, the vibration and noise brought by the explosion are difficult to control. Because the explosion composite and the explosion composite rolling process have disadvantages, the industry urgently hopes to develop a new type of type , Efficient, environmentally friendly stainless steel composite board production technology.

In this context, scholars at home and abroad gradually set their sights on rolling composite technology. With the development of equipment towards large -scale, high -speed, and continuous directions, the use of hot -rolled processes can produce various composite boards at high efficiency, high quality, and low cost, and specially produced a composite board with a width of more than 3000mm that cannot be produced by explosive processes. Compared with the explosion process, it has a significant advantage.
