Problems solved by technology

The thin-clad titanium / steel composite plate produced by this method has high bonding strength, the tensile and shear strength is above 200MPa, and the quality is stable, but it takes a lot of time to obtain the vacuum, so the production cycle is long, which is not conducive to industrial production.
In addition, vacuum equipment is expensive, with a large initial investment and high maintenance costs in the later period

Embodiment 1

[0035] Step 1. Select a Q235A steel plate with a thickness of 64.0mm and a TA1 titanium plate with a thickness of 6.0mm, level the steel plate and titanium plate until the unevenness is 5.0mm / m, and cut the leveled steel plate to a length and width of 200mm ×400mm, cut the leveled titanium plate to a length and width of 150mm×350mm; then use the louver to remove the oxide layer, slag inclusions, cavities and other defects on the surface to be compounded of the cut steel plate and the titanium plate to be compounded, Expose the base metal; clean the steel plate and titanium plate with chemical pure ethanol to completely remove the residual oil and various adsorbates on the surface;

[0036] Step 2, assembling the cleaned steel plate and titanium plate into a slab in step 1; the way of assembling is as follows: figure 1 and figure 2 As shown, the surface to be compounded of the steel plate 1 and the surface to be compounded of the titanium plate 2 are stacked to form a slab, a...

Abstract

The invention discloses a preparation method of high-performance thin clad titanium / steel compound plates, and the method comprises the following steps: step 1) performing treatment on the surface to be compounded of a steel plate and the surface to the compounded of a titanium plate through a mechanical method, removing defects on the surfaces to be compounded and then washing the surfaces to be compounded of the steel plate and the titanium plate clean through an organic solvent; 2) assembling the steel plate and the titanium plate after cleaning into a rolled compact; 3) heating the rolled compact to 780 DEG C-880 DEG C and performing heat insulation for 20 min-180min; 4) sending the rolled compact after heat insulation into a rolling machine for rolling, and cooling to get the compound plate; 5) performing heat treatment on the compound plate; 6) leveling, and then cutting off the head, the tail and a weld joint part so as to get two titanium / steel compound plates, wherein the thickness of clad titanium of each titanium / steel compound plate is not more than 3.0mm, and the shear strength is not less than 180MPa. The method disclosed by the invention is simple and very easy to prepare thin clads, in particular to the titanium / steel compound plates with the clad thickness of less than 3.0mm.

Description

technical field [0001] The invention belongs to the technical field of composite plate preparation, and in particular relates to a preparation method of a high-performance thin-clad titanium / steel composite plate. Background technique [0002] Thin-clad titanium / steel clad plate refers to a titanium / steel double-layer metal clad plate whose cladding thickness does not exceed 3.0mm. Here, the clad layer refers to a titanium layer, and the titanium may be pure titanium or a titanium alloy. At present, this type of composite panel is produced by three methods: [0003] (1) Explosive welding method: Explosive welding is a welding method that uses the energy generated by the explosion of explosives as an energy source to form a firm solid-phase bond between the metals to be welded. A small amount of thin-clad titanium / steel composite panels in China are produced by explosive welding. The composite panels produced by this method have high bonding strength, and the general tensil...
