Abstract

The invention discloses a double-sided titanium steel composite plate using IF steel as a transition layer, and a preparation method thereof. According to the present invention, the composite billet for manufacturing a composite plate comprises IF steel, a titanium composite material and a base material, wherein the base material is common carbon steel or low alloy steel with a C content of less than or equal to 0.22%, the titanium composite material is industrial pure titanium TA2, a thickness ratio of the base material to the titanium composite material is 5-10, the length and the width of the titanium composite material are smaller than the length and the width of the base material, and the distance between the titanium composite material and the four edges of the base material is 60-100 mm; the composite billet after sealing welding treatment is heated to a temperature of 900-920 DEG C, a thermal insulation time is 1 min / mm*the total thickness of the composite billet, the rolling starting temperature is 880-900 DEG C, the rolling finishing temperature is more than or equal to 800 DEG C, the single-pass reduction is 15-20%, and the total reduction is more than or equal to 70%; the thickness of the transition layer of the IF steel after rolling is 180-220 [mu]m; the thickness of the produced double-sided titanium steel composite plate is 6-45 mm; and the product is suitable for pipelines for chlor-alkali, soda ash, petrochemical industry, salt production and seawater desalination, and offshore oil drilling and pipe fittings.

Description

technical field [0001] The invention belongs to the technical field of composite plate preparation, and in particular relates to a double-sided titanium steel composite plate produced by vacuum compounding + rolling technology and a process method thereof. Background technique [0002] Titanium-steel clad plate not only has the excellent corrosion resistance of titanium clad layer, but also has the strength and plasticity of base structural steel. Compared with titanium plate, its economic cost is greatly reduced, especially the double-sided titanium-steel clad It is a titanium plate with strong overall corrosion resistance. It is an ideal material for the manufacture of corrosion-resistant environmental equipment. It has been popularized and applied in petrochemical, salt production, electric power, seawater desalination, marine engineering and other fields with great potential for application. [0003] At present, there are four main methods for producing titanium-steel cl...
