Abstract
The invention relates to the field of metal composite materials, particularly relates to a titanium and steel and stainless steel composite board and a preparation method, and solves the problems that in a process that an explosive composite board is rolled to a thin board, an existing bonding surface is a wavy structure, a substrate of a steel plate is easily exposed in the rolling process, bonding intensity is also low, and the like. The composite board adopts a composite structure composed of a titanium plate, a common steel plate and a stainless steel plate, the common steel plate serves as an intermediate layer, planes of two sides of the common steel plate are respectively composited with the titanium plate and the stainless steel plate, the common steel plate and the stainless steel plate are in a hot rolling extension composite structure, and the common steel plate and the titanium plate are in a hot rolling composite structure. The composite board adopts a method that mild steel with a small brittle phrase produced at a high temperature and the titanium and the stainless steel are heated and rolled, mainly achieves a purpose that ferritic stainless steel is rapidly taken out so as to mutually reach to the hot inlaying combination, and finally the titanium-steel stainless steel composite board is manufactured. According to the preparation method, the titanium and steel and stainless steel composite thin board is manufactured and can be widely applied to industries and civilians for use.
Description
Technical field
The present invention relates to the metallic composite field, be specially a kind of titanium, steel, stainless steel clad plate and manufacture method thereof, adopt the inventive method can produce titanium, steel, stainless steel composite thin plate, this thin plate not only can be used for industry, also can be widely used in civilian.
Background technology
No matter be the powder charge vessel in small pressure container or laboratory, and be used for the industrial circles such as pharmacy, food, chemical industry to the concentrated used small-sized cooler of liquid material, industry is used for discharging the pipeline lining lining with corrosive gas or liquid, and their internal layer has very high requirement to corrosion-resistant intensity.The certain titanium plate of the making of these containers is first-selected material, secondly is corrosion resistant plate.But the price of making of the titanium plate can be very high, makes of corrosion resistant plate, and its corrosion-resistant intensity is undesirable again.
At present, mostly be the material that adopts a kind of titanium steel composite board in industry field, it is corrosion-resistant very desirable that titanium layer is made internal layer, but there are two defectives in this material: the one, and combined strength bination is inadequate, and this is because production technology determines; The 2nd, the steel long term exposure is easily oxidation in air.Because the intensity of titanium and steel differs greatly, the two is difficult to compound, wants the combined strength bination that reaches high, and a kind of method is to add one deck transition zone between titanium plate and steel plate, but the material of transition zone is all very expensive, inadvisable.Another kind method is first steel plate to be forged to improve after its intensity compoundly again, does not take this operation but produce at present in the technique of titanium steel composite board.
In metal material, because the intensity of titanium is very high, stainless steel takes second place, and the intensity of mild steel is lower, and these three kinds of plates are difficult to compound.In the existing technology, all be to adopt the compound method of blast compound with thinner titanium plate or thinner corrosion resistant plate and thicker steel plate.If need thin plate, also want the further rolling thin plate that just can obtain respective thickness, utilize so the compound thin plate that is rolled into again of blast that very large defective is arranged.Reason is the blast compound tense, and compound interface is comprised of direct interface, melting zone and whirlpool, and causing faying face is wavy texture, and bond strength is also lower.Because titanium plate and stainless price are higher, if need titanium and the stainless steel of thin multiple layer, be rolled again with the compound slab of blast, just be easy to expose the basic unit of steel plate, lost its due effect of composite plate.
Summary of the invention
The object of the present invention is to provide a kind of titanium, steel, stainless steel clad plate and manufacture method thereof, solve explosive clad plate in being rolled into the process of thin plate, the faying face that exists is wavy texture, easily exposes the basic unit of steel plate in rolling process, and the also problem such as lower of bond strength.
