Embodiment 1

[0025] Finished product size 4.0×B×L mm

[0026] The steel plate used for cladding is Q235 with a thickness of 14mm; the titanium alloy plate clad with the steel plate is TC4 titanium alloy (corresponding to foreign brands such as GR5 / Ti6Al4V, etc.). The total thickness of the superimposed titanium alloy plate is 17mm; firstly, the surface of the steel plate and the titanium plate is cleaned; then the cleaned two steel plates are covered on the upper and lower sides of the titanium alloy plate, and steel strips are covered on the front, rear, left, and right sides of the titanium alloy plate; Gas-shielded welding is used to weld the upper and lower steel plates and side steel bars, and the titanium plate is sealed inside the steel plate to form a stacked rolling bag; uniformly distributed through holes are left on the side sealing plates around the stacked rolling bag, and the area of ​​the through holes occupies the entire side seal 3%~20% of the board area.

Abstract

The invention discloses a method for preparing a titanium alloy thin plate by cladding and rolling of a steel plate, and relates to a processing method of a metal plate. It is characterized in that the rolling process is that the titanium alloy plate is hermetically covered by a steel plate to form a stacked rolling bag, and then rolling is carried out. The method of the invention has low rolling cost, and the titanium alloy thin plate is produced by cladding, welding, stacking and hot rolling, the process is simple, and the comprehensive performance of the obtained material is excellent.

Description

technical field [0001] The invention discloses a method for preparing a titanium alloy thin plate by cladding and rolling of a steel plate, and relates to a processing method of a metal plate. Background technique [0002] Titanium alloy is a metal material with excellent performance, which is widely used in aviation, aerospace, chemical industry, electronics, sporting goods and other fields. Titanium alloy plate is an important product form, accounting for 40~60% of the total, but it is generally commercially available. The cold working capacity of titanium alloys is relatively low (about 20%). [0003] According to the traditional single-sheet rolling process, multiple hot rolling processes and multiple cold rolling processes are required to produce titanium alloy thin plates. Repeated heating in the middle of the hot rolling processes causes material surface contamination. In order to eliminate surface contamination, repeated alkali pickling is required, which increases t...
