Technical field
The present invention relates to multi-layer metal composite plate material preparation field more particularly to a kind of multi-layer metal composite plate pulse currents
Assist rolling device and method, specifically a kind of Electroplastic and pulse current local heating effect that multiple layer metal plank is made to roll
In conjunction with and the system that reaches good composite effect.
Background technology
Multi-layer metal composite material refers to by certain Combined Machining Technology by the different gold of two or more property
Belong to material, is matched with the constituent element layer of certain thickness and interface, the multilayer knot of firm metallurgical binding is formd in interface
Structure material.Compared with Dispersed precipitate between each constituent element of traditional metallic composite, each constituent element of multi-layer metal composite material is in
Stratiform is continuously distributed, has alternatively distributed group of metamember and interface layer.Deformation of the presence at interface to stratified material
The regulation and control of load play an important roll in journey, regulation and control and reallocation of the stress between each layer constituent element may be implemented so that multilayer
Metallic composite can bear the plastic deformation of bigger.Therefore, multi-layer metal composite material is keeping the same of each constituent element property
When, moreover it is possible to the advantage performance between comprehensive each constituent element so that multi-layer metal composite material has more superior than single metal material

Edge of materials is cracked, in addition, in order to ensure the interface bond strength of plank in the operation of rolling, it is right during the rolling process to need
Plank is heated, and is caused material to form oxide layer, is reduced the combination effect of composite board.
In recent years, a kind of novel pulse electric current auxiliary rolling technique has been developed, by applying during metal rolled
Pulse current is combined with the local heating effect in roll contact region with electro plastic effect using pulse current in material,
So that material resistance of deformation is reduced, plasticity increase, realizes compared with large plastometric set.The pulse current rolling system designed at present is chiefly used in
The operation of rolling of hardly possible deformation single-layer metal, and electric current transmission line is complicated in rolling system, resistance is big, as notification number is：
CN105951020A, it is entitled：" a kind of method that high-strength high-plasticity zirconium and Zr-2 alloy are realized in electro plasticity rolling ",
Pertain only to the rolling process of single layer zirconium and Zr-2 alloy；For another example Authorization Notice No. is：CN202169276U, it is entitled：" one
The system of kind Electroplastic and warm plasticity combination rolled metal material ", then be respectively set in the front and rear sides of roll and connect with rolled piece
Electric current is passed to contact in rolling by tactile electrode assembly by rolled piece.
The pulse current auxiliary milling method that the above patent refers to all is auxiliary to single layer difficulty deformation plank progress pulse current
Rolling is helped, and electric current transmission line is complicated in rolling system, resistance is big, fails to realize Electroplastic and pulse current local heating
The ideal functionality of effect rolling bonding cannot reach pulse current auxiliary rolling multiple layer metal plank and reach good compound
The purpose of effect.
