Abstract

The invention relates to the technical field of steel-titanium composite plate preparation, in particular to a steel-titanium composite plate, wherein at least one of the upper surface and lower surface of a steel plate base layer is compounded with a titanium plate layer. The invention also provides a preparation method of the steel-titanium composite plate, which comprises the following steps: acarbon steel coil strip and a titanium plate are respectively placed at a temperature of 200-200 DEG C for heating and are respectively placed at a temperature of 500-650 DEG C for heating again; theheated carbon steel coil and titanium plate are placed on a cold rolling differential composite rolling mill for rolling and composite forming, a steel-titanium composite plate blank is placed in a bell furnace again, and a diffusion heat treatment sintering process is used, the sintering temperature is controlled at 700-700 DEG C and the sintering temperature is controlled at 20-48 hours. The method has the advantages of low manufacturing cost, good product surface quality, strong interlayer binding force, high thickness control precision and no environmental pollution.

Description

technical field [0001] The invention relates to the technical field of steel-titanium composite plate preparation, in particular to a steel-titanium composite plate and a preparation method thereof. Background technique [0002] As a rare metal, titanium has good comprehensive properties such as low density, high strength, high temperature resistance, corrosion resistance, non-magnetism, sound wave transmission, and shock and vibration resistance. It is a high-quality corrosion-resistant light structural material, a new functional material and an important bioengineering material. Coils and strips made from hot-rolled coils and cold-rolled are widely used in island equipment anticorrosion, seawater desalination equipment, plate heat exchangers, power station condensers, chemical reaction vessels, etc. Its usage accounts for about 80% of the total, and these mainly use the corrosion resistance of titanium metal. Due to the lack of titanium metal resources, the difficulty of...
