High-performance double-sided titanium steel clad plate taking IF steel as transition layer, and preparation method thereof

Abstract

The invention discloses a high-performance double-sided titanium steel clad plate taking IF steel as a transition layer, and a preparation method thereof. A composite blank for manufacturing the cladplate includes IF steel, a titanium composite and a base material; the base material is plain carbon steel or low alloy steel with C being less than or equal to 0.22%; the titanium composite is industrial pure titanium TA2, the thickness ratio of the base material to the composite is 5-10, the length and width of the titanium composite are less than that of the base material, and the edge distances of the titanium composite from the four edges of the base material are 60-100 mm; the composite blank after seal welding can be heated to 900-920 DEG C to perform heat preservation, the heat preservation time is 1 min / mm * the total thickness of the composite blank, an initial rolling temperature is 880-900 DEG C, a finish rolling temperature is greater than or equal to 800 DEG C, air cooling can be performed to room temperature, a single pass reduction rate is greater than or equal to 15%, the first three pass reduction rates are greater than or equal to 20%, and the total reduction rate isgreater than or equal to 75%; and the thickness of the produced clad plate is 6-45 mm, and the thickness of an IF steel transition layer is 80-120 [mu]m. Thus, the clad plate is suitable for structures which have corrosion resistance requirements for inner and outer surfaces and consider integral mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of composite plate preparation, and in particular relates to a process method for producing high-performance 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 techno...
