A kind of production method of stainless steel clad plate

Abstract

The invention provides a production method of stainless steel composite plates. The production method comprises the steps that caulking grooves are dug in the middles of two carbon steel base blanks according to the size of stainless steel plates, and slots and exhaust chambers communicating with the slots are formed in the two ends of each caulking groove separately; the two stainless steel plates are embedded into the caulking grooves of the two base blanks in the mode that the surfaces where an isolating agent is spread face upwards, and the two base blanks are buckled together to form a composite blank; the composite blank is put into a vacuum chamber to be vacuumized, spot welding is conducted first and then continuous welding is conducted, vacuum breaking and cooling are conducted, and an anti-oxidation coating is sprayed on the surface; heating and heat preserving are conducted on the cooled welded blank in a heating furnace, wherein the initial rolling temperature ranges from 1,000 DEG C to 1,150 DEG C, the accumulated reduction rate of the first three passes is higher than or equal to 35%, and the finish rolling temperature ranges from 930 DEG C to 1,050 DEG C; edges are cut after rolling, and then two stainless steel composite plates are obtained. According to the method, the condition that a magnetic deflective blow phenomenon occurs between stainless steel and carbon steel due to magnetic influence can be avoided, effective compositing between the stainless steel and the carbon steel is achieved, the surface clearing and grinding amount is decreased, and the yield of the composite plates is increased.

Description

technical field [0001] The invention belongs to the field of metal pressure processing, and in particular relates to a production method of a stainless steel composite plate. Background technique [0002] As a new type of material, stainless steel composite plate not only has the advantages of strong corrosion resistance, good wear resistance, beautiful and durable, easy to form, etc. of stainless steel, but also has good weldability, formability, drawability and thermal conductivity of carbon steel. At the same time, the invention has low cost, strong adaptability and wide application range. Stainless steel clad panels are usually made of stainless steel as the cladding layer, and carbon steel or alloy steel as the base layer. The stainless steel cladding can ensure the corrosion resistance of the product, while the base layer can ensure the strength of the product. The use of stainless steel composite panels can effectively reduce costs and save precious metals such as n...

Problems solved by technology

At present, there are mainly two methods. One is to install protective gas nozzles during the heating process and rolling process of stainless steel-carbon steel clad plates to blow argon to slow down the oxidation of the interface, but this method is only suitable for thin strips. Certain effect, but nothing for thick plates
