Embodiment 1

[0035] Example 1: A titanium-aluminum-stainless steel clad plate with a thickness of 3.15 mm as a hot-rolled composite product.

[0036] Among them: imported titanium plate with a thickness of 0.6mm, 1050 pure aluminum plate with a thickness of 3mm, and 304 stainless steel plate with a thickness of 0.9mm.

[0037] ①Titanium plate pre-treatment: place the titanium plate in an annealing furnace of 500-9000 for annealing treatment, the time is 25-50 minutes, take it out and cool it naturally;

[0038] ②Interface treatment: Sandblast and frost the interface of titanium plate, pure aluminum plate and stainless steel plate to be combined to clean the residual oxide layer on the surface of the three plates. The depth of grinding is 0.2-0.6mm. The aluminum plate and the stainless steel plate are rinsed clean, and finally dried at a temperature of 100-200°C for 5-10 minutes;

[0039]③Heating treatment: After aligning the composite interfaces of the titanium plate, pure aluminum plate,...

Embodiment 2

[0045] Example 2: A titanium-aluminum-stainless steel clad plate with a thickness of 5.0 mm as a hot-rolled composite product.

[0046] Among them: the thickness of titanium plate is 1.0mm titanium plate, the thickness of aluminum plate is 5.0mm pure aluminum plate, the thickness of stainless steel plate is 316L stainless steel plate of 1.5mm, its actual operation process is basically the same as that of example 1, the difference is that the heating time is correspondingly increased by 5 -20 minutes, that is, 15-50 minutes, the reduction rate is 33% of the original total thickness of the composite plate, and finally the composite finished product is a titanium-aluminum-stainless steel composite plate with a thickness of 5.0 mm.

Embodiment 3

[0047] Embodiment 3: A titanium-aluminum-stainless steel clad plate with a thickness of 1.24mm is hot-rolled.

[0048] Among them: the imported titanium plate with a titanium plate thickness of 0.5mm, the 1050 pure aluminum plate with a thickness of 1.0mm, and the 304 stainless steel plate with a stainless steel plate thickness of 0.5mm. When riveting, two sets of plates are used to superimpose and complete hot rolling. There are six plates in total. The specific arrangement method is: stainless steel plate, aluminum plate, titanium plate, titanium plate, aluminum plate, stainless steel plate, and between the two titanium plates. A special anti-adhesive agent is added in between, the anti-adhesive agent can be magnesium oxide powder, the time of rolling and heating is adjusted according to the total thickness of the composite plate, the reduction rate is 38% of the original total thickness of the composite plate, and other parts The process is the same as in Example 1. Finally...

Abstract

The invention discloses a novel hot-rolled titanium-aluminum-stainless steel compound plate, a production method and an application thereof. The compound plate comprises a three-layer structure which consists of a titanium plate, a pure aluminum plate and a stainless steel plate. The production method of the compound plate comprises the following steps: pre-annealing the titanium plate for a period of time; blasting sand and frosting an interface to be compounded among the titanium plate, the pure aluminum plate and the stainless steel plate, washing the surface and increasing the surface area; aligning, folding and riveting the three plates, and heating at curve temperature; finally, rolling and compounding, annealing, leveling and performing surface treatment. Through the production method of the compound plate, the titanium-aluminum-stainless steel compound plate with any thickness can be hot rolled and produced; the products are strong in binding force; the products are not deformed, creased and layered in the subsequent processing treatment; the products have the advantages of excellent corrosion resistance, great compressive strength, low cost, light weight, fast heat dissipation, slow sound transmission, high-strength and high-smooth surface appearance and the like; the products are mainly applied to the food industry, the chemical industry, the shipbuilding industry, the automobile industry, the building industry, the household appliances manufacturing industry and the like, such as composite frying pans, houseboats and so on.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a novel hot-rolled titanium-aluminum-stainless steel composite plate and its production method and application.
