Embodiment 1

[0029] In this embodiment, the Q235B steel grade with a substrate thickness of 66 mm is selected, the industrial pure titanium TA2 with a thickness of 6 mm as a cladding material, and a TA2 / Q235B composite plate with a thickness of 0.5+5.5 mm as a rolled product.

[0030] Ⅰ. Surface treatment: Grind the surface to be compounded of two Q235B substrate blanks and two TA2 cladding blanks, remove the rust layer and oxide layer on the surface of the blanks, and expose the fresh metal on the surface completely.

[0031] Ⅱ. Application of release agent: Apply release agent to the unpolished surface of the cladding material, and then dry the release agent.

[0032] Ⅲ. Symmetrically combined blank: select one of the base materials as the blank, and fix it with seal spot welding around the surface to be compounded. The width of the seal is 30mm and the thickness is 13mm. The base material is to be compounded in the groove surrounded by the seal. every 0.5 meters (see figure 1 Arrow dis...

Abstract

The invention discloses a preparation method of a titanium-steel composite board. The titanium-steel composite board with high binding property is prepared through process as follows: blank preparation, surface treatment, painting of a parting agent, symmetrical assembling, electron beam sealing weld, heating, rolling, straightening, cutting partition and the like. Laminations are added to a to-be-composited titanium-steel interface in an assembling process, so that titanium and steel in a composite blank cannot be contacted sufficiently, mutual diffusion of elements in a heating process of titanium and steel is prevented, and generation of brittle phases such as carbide, intermetallic compounds and the like on the interfaces is controlled; then an oxidation film on the interface is damaged by high reduction rolling, a new titanium-steel binding interface is formed and sufficient metallurgical binding is realized, rapid cooling is performed after rolling, regeneration of the brittle phases is inhibited, and the brittle-phase-free titanium-steel composite board with high binding property is prepared. Compared with addition of intermediate nickel foil or copper foil, the preparationmethod has the advantages of being simpler to operate and lower in production cost, and the binding property is higher.

Description

technical field [0001] The invention belongs to the technical field of bimetal composite manufacturing, and relates to the preparation of a composite plate, in particular to a preparation method of a titanium-steel composite plate. Background technique [0002] Titanium has significantly excellent corrosion resistance. In most corrosive environments, its corrosion resistance exceeds that of stainless steel. Therefore, it is widely used in chemical equipment, pressure vessels, heat exchangers, offshore operating platforms, aerospace and other fields. . However, titanium is expensive, which increases the material cost of equipment manufacturing, which limits the use of titanium. The titanium-steel composite plate has both the excellent corrosion resistance of titanium and the strength and toughness of steel, and greatly reduces the amount of titanium used, saving costs, and has high economic value and good application prospects. [0003] At present, the main preparation meth...
