Ti / Cu Composite Rod Rolling Composite Technology And Interface Bonding Mechanism Studies

One of layers composite of metal -titanium copper cladding bar which compounds excellent to be electrolytic and chlorine alkali to make industry get extensive application at present. The excellent method to prepare titanium copper cladding bar mainly for welding explode + roll of compounding and extruding of compounding in the past. This text is studied to compound with type hole legal system prepares against titanium copper cladding bar excellent and to propose for the first time. Have designed three sets of corresponding roll passes according to the needs of section measurement of the finished product, three pass which play a positive role to roll in compound course deformation amount combine to interface influence of bonding intensity.While studying the rolling influence of the course to rolling compounding of craft parameter, have probed into the rolling temperature and influence of deformation amount especially. The experiment indicates, the titanium copper cladding bar excellent roll compounds and needs to realize through hot rolling. Heating temperature and deformation amount have decisive influence to combine the intensity on the interface, deformation amount is smaller like 56%, heating temperature should be relatively high, can reach more than 790 degrees Centigrade, and deformation amount is greater such as 64% and 70%, temperature can be reduced properly to about 750 degrees Centigrade, but how change deformation amount, heating temperature can not exceed 850 degrees, in order to prevent interface from turn into harmful metal chemical compound and influence the quality of compounding, titanium copper cladding bar that roll after compounding getting like this compound excellent interface is combine for metallurgy to combine, and that the intensity approach the pure copper.Through interface compound for titanium copper cladding bar of metallurgy combining excellent interface strip picture go on analyze and combination intensity that correspond to it relatively correctly, draw titanium copper cladding bar compound excellent to store two kinds in combine mechanism mainly in the course of rolling and compounding, one mechanical function make titanium copper cladding bar two kinds of metal surface produce the breachand realize through pressure function of rolling mill that accords with tentatively mainly, amount of breach with cause density main factor combined for the first time to influence, this .can through increase deformation amount of metal can be improving; Second combination mechanism , is rolling after compounding excellent cooling anneal course to show mainly, the higher rolling temperature, the more abundant to spread the course, this has decisive influence too in combining the intensity finally.Theory analysis indicate with experiment research, prepare against with pass rolling to prepare titanium copper cladding bar excellent craft feasible, and a kind of better complex methods. Studying data got has certain directive significance excellently in rolling and compounding to produce the titanium copper cladding bar on a large scale.
