Description
Technical Field
The invention relates to the field of metal composite materials, in particular to a titanium, steel and stainless steel composite plate and a manufacturing method thereof.
Background
The inner lining of pipelines for discharging corrosive gases or liquids, which are small pressure vessels or laboratory drug-containing vessels, and small coolers for concentrating liquids in the industrial fields of pharmacy, food, chemical industry and the like, have high requirements on corrosion resistance. The fabrication of these vessels is of course titanium plate being the preferred material, followed by stainless steel plate. However, the price of titanium plate is high, and the corrosion resistance is not ideal when stainless steel plate is used.
At present, the titanium steel composite board is mostly adopted in the industry field, and a titanium layer is used as an inner layer and is ideal in corrosion resistance, but the material has two defects: firstly, the composite strength is not enough, which is determined by the production process; secondly, steel is easy to oxidize after being exposed in air for a long time. Because the strength of titanium and steel is very different, the titanium and steel are difficult to be compounded, and in order to achieve high compound strength, one method is to add a transition layer between a titanium plate and a steel plate, but the materials of the transition layer are very expensive and are not preferable. The other method is to forge the steel plate to improve the strength and then compound the steel plate, but the process is not adopted in the prior process for producing the titanium steel composite plate.
In the metal material, because the strength of titanium is high, stainless steel is inferior, and the strength of low-carbon steel is low, the three plates are difficult to compound. In the prior art, a thinner titanium plate or a thinner stainless steel plate and a thicker steel plate are compounded by adopting an explosion cladding method. If a thin plate is needed, the thin plate is further rolled to obtain a thin plate with a corresponding thickness, so that the thin plate manufactured by explosion cladding and rolling has a great defect. The reason is that the composite interface is composed of a direct junction area, a melting layer and a vortex during explosive cladding, so that the joint surface is of a wavy structure and the joint strength is low. Because titanium plates and stainless steel have high prices, if thin and multiple layers of titanium and stainless steel are needed, the base layer of the steel plate is easily exposed by rolling the explosion-clad plate blank, and the due effect of the composite plate is lost.
