Abstract

The invention discloses a preparation method for an aluminum-stainless steel clad metal plate and strip. The method comprises: carrying out anaerobic continuous casting and rolling on semisolid aluminum or aluminum alloy and a solid stainless steel plate strip to prepare the aluminum-stainless steel clad metal plate strip. In the preparation method of the invention, the non-oxidation metallurgy composite of the solid stainless steel plate strip and aluminum liquid is realized, the oxidation problem of the aluminum is solved, the composite strength is high, and the bond strength of the stainless plate and the aluminum is larger than or equal to 100Mpa; continuous casting and rolling is carried out on the stainless plate strip and the aluminum liquid to prepare the aluminum-stainless steel clad metal plate strip, the production efficiency is greatly improved by up to dozens of times, and the product quality is stable; the prepared aluminum-stainless steel clad metal plate strip product maintains the intrinsical surface quality of the stainless steel plate strip, and the stainless steel layer has even thickness and can be performed with cold rolling and deep processing; various stainless steel plate and strips with different components and the aluminum liquid can be adopted, the sorts of products are more, and the applicability is wide; and the invention has the advantages of advanced production process, less working procedure, energy conservation, materials saving and remarkable economic effects.

Description

technical field [0001] The invention relates to the technical field of manufacturing metal strips, in particular to a method for manufacturing aluminum and stainless steel composite metal strips. Background technique [0002] Stainless steel and aluminum are important metals widely used in industrial and civil fields. Stainless steel will not cause corrosion, pitting, rust or wear. Stainless steel is also one of the strongest materials among metal materials used in construction. Due to its good corrosion resistance, stainless steel can make structural components permanently maintain the integrity of engineering design . Chromium-containing stainless steel also combines mechanical strength and high elongation, and is easy to process and manufacture parts, which can meet the needs of architects and structural designers. Aluminum has a small specific gravity, good electrical and thermal conductivity, and aluminum resources are abundant and cheap. [0003] Aluminum and stainl...
