Description

Technical Field

[0001] The utility model relates to the technical field of titanium-aluminum alloy rolling, in particular to a stainless steel sheath for rolling titanium-aluminum alloy plates. Background Art

[0002] Titanium-aluminum alloy sheath rolling is a method of fusing titanium alloy and aluminum alloy together to form a composite material. Through this method, the strength, corrosion resistance and wear resistance of the material can be effectively improved, and the weight of the material can be reduced, and its performance can be improved. At the same time, it can also improve the thermal stability of the material and extend the service life of the material.

[0003] The reasons for wrapping the titanium aluminum alloy plate with a stainless steel sheath during rolling are as follows: first, the sheath can coordinate plastic deformation, prevent interlayer cracking, and reduce internal cracks in the material; second, the sheath can prevent the plate from being dislocated during rolling, thereby reducing the difference in deformation; in addition, the sheath can also greatly reduce heat loss, hinder crack propagation, and effectively prevent the alloy from oxidation. Especially when rolling titanium aluminum alloy, which has a large difference in strength and plasticity, it is more necessary to carry out sheathing before rolling because the problem of uncoordinated deformation is easy to occur during the rolling process.

[0004] At present, the sheath used in the rolling of titanium-aluminum alloy plates is wrapped around the outside of the titanium-aluminum alloy plates by welding. During the rolling process, gaps are easily generated at the welds and edges of the sheath, thereby weakening the thermal insulation capacity of the sheath. In addition, the titanium-aluminum alloy plates are not easy to fall off from the sheath after rolling. Utility Model Content

By clamping and then welding, the sealing of the sheath can be improved, and the gaps generated at the weld and the edges of the sheath during the rolling process can be reduced, thereby improving the thermal insulation performance of the sheath. In addition, the use of a structure that is narrow at the top and wide at the bottom can help the titanium-aluminum alloy plate to fall off from the sheath after rolling is completed. The utility model is easy to use and can effectively solve the problems in the background technology.
