Embodiment 1
[0032] The present invention also provides a preparation method of titanium-steel-titanium composite plate, comprising the following steps:
[0033] S1: First select the raw materials for making composite boards, and process the raw materials. By processing the raw materials, the composite boards can be better compounded and the quality of the composite boards can be improved;
[0034] S2: Heating the processed raw material, so that the raw material is fully softened below its metal recrystallization temperature, which is conducive to the maximum realization of large deformation and warm-state rolling compounding to achieve a better rolling effect;
[0035] S3: After the raw materials are heated, use an irreversible large rolling force warm rolling mill to carry out warm-state composite rolling on the rolled piece at its metal recrystallization temperature, so that the three-layer strip is composited into one, and in the rolling process In order to ensure the combination fastn...

Abstract
The invention relates to the technical field of composite plates, in particular to a titanium-steel-titanium composite plate and a preparation method thereof. The titanium-steel-titanium composite plate comprises two titanium plates and a carbon steel plate, and the two titanium plates are fixed to the upper portion and the bottom of the carbon steel plate respectively. The preparation method comprises the steps that 1, raw materials for manufacturing the composite plate are selected; 2, the treated raw materials are heated; 3, after the raw materials are heated, an irreversible large-rolling-force warm rolling mill is adopted; 4, after rolling is completed, heat treatment is conducted on the rolled composite plate; 5, stretching, straightening and levelling treatment is conducted on the composite plate obtained after heat treatment; and 6, edge cutting and reshaping treatment is conducted on the composite plate, and then the final composite plate product is obtained and used for beingused by people. According to the titanium-steel-titanium composite plate and the preparation method thereof, the phase change temperature or below is applied to the raw materials for preheating and heating, the wide composite plate with the comprehensive properties such as the high corrosion-resistant surface and the high strength is obtained, and meanwhile a large amount of precious metal consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of composite plates, in particular to a titanium-steel-titanium composite plate and a preparation method thereof. Background technique [0002] Titanium is considered a rare metal due to its dispersed and difficult extraction in nature. But it is relatively rich, ranking tenth among all elements. Titanium ores mainly include ilmenite and rutile, which are widely distributed in the crust and lithosphere. Titanium exists in almost all organisms, rocks, water bodies and soils. Extraction of titanium from primary ores requires the Kroll or Hunter process. Titanium is widely used because of its good properties, but now the simple titanium plate can no longer meet people's needs, so we propose a titanium-steel-titanium composite plate and its preparation method. Contents of the invention [0003] The object of the present invention is to propose a titanium-steel-titanium composite plate and a preparation met...
