Description
Technical field
The present invention relates to the manufacturing technology of a kind of blast-rolling large tracts of land composite, the preparation method of particularly a kind of blast-rolling large tracts of land titanium steel composite board.
Background technology
The titanium steel composite board that adopts blast-milling method to make is subjected to the restriction of existing market titanium plate supply of material size,
In order to satisfy the different size requirement of user, following two kinds of solutions are arranged to titanium-steel composite board:
The one, the titanium steel composite board of blast-after rolling is spliced.This method has increased the welding capacity of follow-up titanium steel composite board greatly, and a not only multiple layer titanium needs welding, and basic unit's steel also needs welding, and iron solubility in titanium is very low, generally has only the 0.1%(mass fraction), surpass this limit, can generate TiFe, TiFe
2Intermetallic compound makes the serious embrittlement of weld seam.When therefore titanium steel composite board welds, could realize that base steel layer and titanium do not fuse for multiple layer mutually by structural design and the rational welding parameter of selecting, promptly titanium and titanium, steel and steel weld separately.Therefore this method welding job amount is big, production cost is high, production efficiency is low.
The 2nd, an original multiple layer titanium plate of purchasing is spliced.This method only need will be original be answered a layer titanium plate and spliced and get final product before blast-rolling.But with the welding point after such titanium plate welding, must stand the enormous impact effect of detonation wave in the postorder explosive welding process and the roll-in repeatedly in the operation of rolling, therefore require the titanium welding point must have good toughness and ductility.But because titanium has the fusing point height, thermal capacitance is big, special natures such as poor thermal conductivity and chemism height, and its solder technology is popularized far away from the stainless steel welding, and is complicated stricter than the stainless steel welding aspect requiring in weld seam protection measure, technological specification and operation.During welding titanium material, weld seam and high-temperature heat-affected zone metal are easily had an effect with gases such as airborne oxygen, hydrogen, nitrogen on the one hand, and the compound effects that contains elements such as oxygen, carbon, nitrogen, hydrogen that adheres to the workpiece welding wire surface, by oxygen, carbon, nitrogen, hydrogen contaminating impurity, the intensity and the hardness of joint are raise, plasticity descends, and easily produces defectives such as pore, crackle; On the other hand, titanium weld seam and high-temperature heat-affected zone crystal grain are easily grown up, and the plasticity of joint is descended.Except that guaranteeing the performance of weld metal, also must guarantee the performance of welding heat affected zone during welding.This welding method technology requires complicated strict.
Through patent retrieval, still do not explode at present-the rolling large tracts of land titanium steel composite board relevant patent documentation report of multiple layer titanium plate welding method.
Summary of the invention
Technical problem to be solved by this invention provides the welding method of a kind of blast-rolling large tracts of land titanium steel composite board with multiple layer titanium plate, to satisfy the requirement of user to the titanium steel composite board different size.
For the purpose that realizes solving the problems of the technologies described above, the present invention has adopted following technical scheme:
The preparation method of a kind of blast of the present invention-rolling large tracts of land titanium steel composite board comprises following technology:
