Double-sided titanium steel composite plate taking IF steel as transition layer and high-temperature preparation method thereof

Abstract

The invention discloses a double-sided titanium steel composite plate taking IF steel as a transition layer and a high-temperature preparation method thereof. A composite blank for preparing the composite plate comprises a base material, the IF steel and a titanium composite material, wherein the base material is plain carbon steel or low alloy steel with C less than or equal to 0.22%, the titanium composite material is industrial pure titanium TA2, the thickness ratio of the base material to the titanium composite material is 5-10, the length and width of the titanium composite material are smaller than those of the base material, and the margin between the titanium composite material and four sides of the base material is 60-100 mm; and the vacuum welded composite blank is heated to 1040-1060 EDG C for heat preservation, the heat preservation time is 1 min / mm * the total thickness of the composite blank, the initial rolling temperature is 1020-1040 DEG C, the single-pass reduction rate is 15%-25%, the total reduction rate is greater than or equal to 70%, the finish rolling temperature is greater than or equal to 850 DEG C, air cooling is carried out to a room temperature, the thickness of the rolled IF steel transition layer is 280-320 [mu]m, and the double-sided titanium steel composite plate with the thickness of 6-75 mm is obtained after plate splitting, and excellent corrosion resistance and mechanical properties are achieved.

Description

technical field [0001] The invention belongs to the technical field of composite plate preparation, and in particular relates to a high-temperature preparation method for producing double-sided titanium-steel composite plates using vacuum compounding + rolling technology. 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. In recent years, many scholars have conducted research on the te...
