Problems solved by technology

Although this process can prevent titanium and steel from being oxidized when they are heated and rolled, and produce titanium / steel clad plates, this method has the following problems: the titanium plate is used as a side seal to seal the surrounding of the combined billet, and the titanium metal is wasted Large, cost increases, and this method is only suitable for the production of small-sized titanium / steel composite panels. If a large-sized vacuum chamber is built, the cost is high, and each time the vacuum chamber is vacuumed, it is time-consuming and energy-consuming. The cycle is long, which is not conducive to high-efficiency factory production

Abstract

The invention provides a blank production method for embedded vacuum rolling of a titanium / steel composite plate. The method not only can prevent the oxidation of surfaces, to be compounded, of titanium and steel to obtain the high-quality titanium / steel composite plate, but also is suitable for high-efficiency industrialized production.

Description

technical field [0001] The patent of the present invention relates to a billet assembly method for producing titanium / steel layered metal. Specifically, it refers to the vacuum rolling method in which the multi-layer titanium metal is embedded. Background technique [0002] Titanium / steel composite plate is an important branch of layered metal composite materials. The melting point of titanium is 1668°C and the density is 4.51g / cm 3 The advantages of titanium plates are: no corrosion in seawater, no corrosion in organic acids (except oxalic acid and formic acid), good sound transmission, non-magnetic, and non-magnetized. Its disadvantage is high cost, especially when used as a structural component. The titanium-steel composite plate not only has the corrosion resistance of the titanium plate, but also has the strength and plasticity of the ordinary steel plate as a structural part, and the most important thing is that the cost has been greatly reduced. [0003] The applic...
