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 the stainless steel-carbon steel clad plate to blow argon to slow down the oxidation of the interface, but this method is only suitable for thin strips. It has a certain effect, but it can’t be do

Abstract

The invention relates to a preparation method of a stainless steel-carbon steel composite board, which belongs to the technical field of material and comprises the following steps: (1) removing and cleaning rusted layers and oxidative layers of stainless steel board material and carbon steel board material; (2) alternately stacking the stainless steel board material and the carbon steel board material; (3) arranging a composite blank between two metal panels to constitute a clamped composite blank, or welding two composite blanks together by electric welding to constitute a combined structure of the composite blank, a blocker and the composite blank, and arranging the combined structure between two metal panels to constitute a clamped composite blank; (4) welding the peripheries of contact surfaces of two adjacent steel boards under a vacuum condition; (5) arranging the composite board in a resistor furnace for heating and heat preservation; and (6) rolling the composite board by a rolling mill. The method disclosed by the invention prolongs the service life and enlarges the application scope of the stainless steel-carbon steel composite board. Compared with an explosive compounding method, the method causes small environmental pollution, and has low requirements on the production environment, in addition, the shape of the board is flat, and the product yield is high.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a preparation method of a stainless steel-carbon steel composite plate. Background technique [0002] Due to its corrosion resistance of stainless steel and the low cost of carbon steel, stainless steel-carbon steel composite panels are widely used in many industrial fields such as energy, petroleum, and chemical industry; at present, the production of stainless steel-carbon steel composite panels The methods mainly include explosive composite method, brazing composite method and rolling composite method. [0003] Explosive compounding method is a method widely used in China at present. This method can compound two metals with very different melting points, and the compounding is completed in an instant, so it can avoid the generation of intermetallic compounds at the interface. However, this method The composite board produced by the method is small in size and p...
