Abstract

The invention relates to a production method of a 304 stainless steel and a pure-copper cold compound coiled material. The production method comprises the following process steps of: (1) preparing raw materials: carrying out surface oil-removing and decontaminating treatment on 304 coldly-rolling stainless steel and a pure-copper coiled material; (2) carrying out compound rolling: conveying the 304 coldly-rolling stainless steel and a copper metal material into a compound rolling machine to carry out synchronous room-temperature continuous compound rolling; (3) dispreading and annealing: carrying out the dispreading and annealing on a rolled stainless steel copper compound coiled material on an alloy layer; (4) flattening the stainless steel copper compound coiled material which is dispread and annealed; (5) carrying out bending and strengthening treatment on the flattened stainless steel copper compound coiled material; and (6) carrying out cutlengthing and splitting on the stainless steel copper compound coiled material to form a 304 stainless steel and copper cold compound material. The production method disclosed by the invention has a simple manufacturing process and low production cost; and the corrosion resistance of the steel-copper compound coiled material is strong and no rusts are formed on the end surfaced of the steel-copper compound coiled material, so that the requirements of a plurality of indoor and outdoor decorative materials are met.

Description

technical field [0001] The invention relates to a production method of 304 stainless steel and pure copper cold composite coil, belonging to the technical field of stainless steel and copper composite materials. Background technique [0002] 304 stainless steel is a common general-purpose stainless steel, also known as 18 / 8 stainless steel in the industry, with excellent stainless corrosion resistance and better resistance to intergranular corrosion. Rust resistance is stronger than 200 series stainless steel materials. It is also better in high temperature resistance, and the general use temperature limit is less than 650°C. The corrosion resistance is better than 430 stainless steel, but the price is cheaper than 316 stainless steel. It is suitable for daily life and is a nationally recognized food-grade stainless steel. It is suitable for food processing, storage and transportation; it has good processing performance and weldability , Suitable for plate heat exchangers,...
