Description

A kind of preparation method of high-performance thin compound layer titanium/steel composite board
Technical field
The invention belongs to the composite plate preparing technical field, be specifically related to a kind of preparation method of high-performance thin compound layer titanium/steel composite board.
Background technology
Thin compound layer titanium/steel composite board is meant that multiple layer thickness is no more than the titanium of 3.0mm/steel double-level-metal composite plate.Here, multiple layer refers to that titanium layer, titanium can be pure titanium or titanium alloy.At present, such composite plate adopts three kinds of method productions:
(1) explosive welding method: explosive welding is exactly to utilize the energy of explosive charge generation as the energy, makes and is formed a kind of welding method that firm solid phase combines between the weldering metal.Domestic a small amount of thin compound layer titanium/steel composite board adopts the explosive welding method to produce, and the composite plate that this method is produced has high bond strength, generally draws to cut intensity and be not less than 240MPa.But the quality of explosive clad plate is unstable, is embodied in the composite plate of different batches, same batch different composite plate even its binding ability of zones of different of same composite plate and often exists than big-difference.Secondly, explosive welding productivity ratio is low, and especially when multiple layer thickness during less than 1.0mm, shock wave makes compound plate produce disturbance, and limit portion effect is serious, even phenomenon such as appearance does not combine, compound plate is breakdown, and technology difficulty is very big.
(2) blast-rolling: for overcoming of the restriction of multiple layer thickness, explosive welding is combined with rolling technique, developed blast-rolling to process conditions.This method can be produced the thin multiple layer composite plate of multiple layer thickness below 1.0mm easily, become the main method of domestic production thin compound layer titanium/steel composite board, but this " two-step " production increases severely manufacturing cost.Even more important ground, rolling heating before can make the interface form a large amount of fragility phases, and the composite plate binding ability sharply worsens, and draw and cut the only about 140MPa of intensity, in addition lower.
In addition, above-mentioned two kinds of methods also exist noise and shock wave to pollute, and are unfavorable for environmental protection.
(3) vacuum hot rolling method: vacuum hot rolling is that (vacuum is not less than 10 usually in vacuum -1Pa) under the condition, adopt rolling complex technique to produce a kind of new technology of titanium/steel composite board.Abroad, especially in Japan, vacuum hot rolling has become the main production method of thin compound layer titanium/steel composite board, but does not domesticly still possess this technology.The thin compound layer titanium/steel composite board that adopts this method to produce has higher binding strength, and draw and cut intensity more than 200MPa, and steady quality, but vacuum is obtained the need labor time, thereby the production cycle is long, is unfavorable for suitability for industrialized production.In addition, vacuum equipment is expensive, once has high input, and the later maintenance expense is high.
