Ply-rolling pack for pack ply-rolling of titanium alloy sheet

Abstract

The invention discloses a ply-rolling pack for pack ply-rolling of a titanium alloy sheet, and relates to the ply-rolling pack which is used in the production process of rolling the titanium alloy sheet by a ply-rolling method. The ply-rolling pack is characterized by comprising a ply-rolling pack core block and a ply-rolling pack cover, wherein the ply-rolling pack core block is a square core block which is formed by directly laminating titanium alloy sheets; the ply-rolling pack cover comprises surface covering steel sheets and lateral sealing steel sheets; the surface covering steel sheets are attached to the outside the uppermost layer of titanium alloy sheet and the lowermost layer of titanium alloy sheet of the ply-rolling pack core block; the lateral sealing steel sheets are attached to the side faces of the ply-rolling pack core block; the steel sheets are mutually welded to form a square pack cover; and a pair of opposite lateral sealing steel sheets are provided with through holes. Through the ply-rolling pack, the problems of pack breaking, cracking, moving and folding of a core sheet, piling and the like in the hot rolling process can be solved, and finally the titanium alloy sheet with uniform size and high performance is machined.

Description

technical field [0001] The invention relates to a rolling ladle for cladding and rolling a titanium alloy thin plate, which relates to a rolling ladle in the production process of rolling a titanium alloy thin plate by a lamination rolling method. Background technique [0002] Titanium alloy is a kind of metal material with excellent performance, which is widely used in aviation, aerospace, chemical industry, electronics, sporting goods and other fields. Titanium alloy plate is its important product form, accounting for 40%~60% of the total, but generally The cold working capacity of commercial titanium alloys is relatively low (about 20%), so there are problems such as long production cycle, low yield, and poor surface quality in the process of plate processing, and the use of cladding and rolling processing methods will make these problems Easy to solve. In order to achieve regular size, uniform thickness, and good structural properties of clad and rolled plate products, ...
