Problems solved by technology

But at present, there is only the asynchronous rolling composite production process of pure aluminum and stainless steel, but there is no composite plate production process of aluminum alloy and stainless steel. Because pure aluminum is soft, it can be easily composited with stainless steel, while aluminum alloy is hard, so it is difficult to composite with stainless steel. In the field of electronic products and military products, more and more raw materials of aluminum alloy and stainless steel composite plates are needed to process the required products. Although there are other composite methods, such as explosive compounding, etc., the efficiency is not high. How to realize the continuous production of aluminum alloy and stainless steel composite plates Large-scale production and high production efficiency are difficult problems to solve

Abstract

The invention discloses an asynchronous cold rolling forming process of an aluminum alloy stainless steel composite plate. The process comprises the following process steps: 1, rolling and compoundinga stainless steel plate and an aluminum alloy plate in an asynchronous rolling mode, and 2, after asynchronous rolling, diffusing and annealing the composite plate, specifically, in the step 1, online heating is carried out on the opposite surface of the composite plate surface of the stainless steel plate, online cooling is carried out on the opposite surface of the composite plate surface of the aluminum alloy plate online, and the heating temperature is 350 DEG C-850 DEG C; the temperature of the composite plate surface of the stainless steel plate from which the composite plate is rolledis lower than 650 DEG C, and the temperature of the composite plate surface of the aluminum alloy plate from which the composite plate is rolled is lower than 300 DEG C; the rolling reduction rate is20%-90%; the different speed ratio of a roller for asynchronous cold rolling is 1.05-1.50; the thickness ratio of the aluminum alloy plate to the stainless steel plate is 1.5-4.0; and in the step 2, the annealing temperature is 250 DEG C-500 DEG C and the annealing time is 15-120 min. The single-side online heating process for rolling the composite plate is creatively provided so as to improve theinterface bonding strength of the composite plate and realize rolling compounding in an interface semi-melting state.

Description

technical field [0001] The invention relates to an asynchronous cold rolling forming process of an aluminum alloy stainless steel composite plate. Background technique [0002] Metal composite plate is a new type of composite material prepared by using composite technology to make two or more metal plates with different physical, chemical and mechanical properties realize firm metallurgical bonding at the interface. Compared with single-component metal materials, metal composite panels after reasonable design and combination combine the characteristics of each component metal, have excellent performance, and are low in price, green and environmentally friendly, and have developed rapidly in China in recent years. The manufacturing methods of metal clad plates include powder metallurgy, liquid-solid phase rolling, explosive cladding, hot rolling cladding, cold rolling cladding, etc. Among them, the processing temperature of the cold-rolling composite method is low, the compo...
