Problems solved by technology

The hot-rolled titanium-steel clad plate requires a large-scale rolling mill, and the rolling thickness of the large-scale rolling mill is more than 12mm. However, many occasions in the market need to use 1-2mm thick titanium-steel clad plate, which cannot be achieved by hot rolling.

Abstract

The invention discloses a production method of a cold-rolled titanium-steel composite board. The production method includes the following processing steps: (1) assembling semi-finished products, (2) rolling assembled blank with a hot rolling mill set, (3) uncoiling after the blank is rolled, and dividing into two single-face rolls or two single-face rolls and one double-face single-face roll, (4) annealing and naturally cooling to a normal temperature for normal temperature scouring, and rolling with a cold rolling mill after scouring to obtain the needed titanium-steel composite board. According to the production method of the cold-rolled titanium-steel composite board, the process design is rational. After the assembling of the semi-finished products, hot rolling is conducted first, and then cold rolling is conducted, and after the cold rolling, the titanium-steel composite board with the thickness being 1-2 millimeters can be obtained.

Description

technical field [0001] The invention relates to a method for preparing a composite steel plate, in particular to a method for producing a cold-rolled titanium-steel composite plate. Background technique [0002] Titanium-steel clad plates are widely used in energy, petroleum, chemical, marine and other sectors due to their excellent corrosion resistance and remarkable economy. There are two main methods of producing titanium-steel clad plates: one is the explosive clad method, and the other is the rolling clad method. The products produced by the explosive cladding method have small boards, low production efficiency, low bonding strength, and a staggered bonding cross-section, which reduces the effective thickness of the titanium layer. The rolling compounding method is further divided into cold rolling compounding method and hot rolling compounding method. The hot rolling compounding method can be produced on a large scale, and the interface bonding rate and interface bond...
