Section 1 overview
Titanium composite is a new metal material with high cost performance.There are a variety of processing methods for titanium coating, such as explosive welding 4, explosive welding + rolling and extrusion.The first two methods are used in the production of composite plate, while the second method is mainly used in the production of composite bar and composite pipe
Section 2 conventional compound methods
explosive welding and explosive welding + rolling
The explosive welding technology of titanium composite materials develops rapidly, which not only produces titanium steel, but also realizes the production of a series of titanium alloy composite materials, including titanium - copper, titanium - nickel, titanium - steel - titanium, titanium - steel - stainless steel, titanium - niobium - stainless steel, titanium - copper - aluminum - stainless steel and so on.At present, the area of the composite wood t can reach 25m2, the area of the composite wood t can reach 35m2 by explosion + rolling, and the thickness of M layer varies from 1.2 to 12mm.
Two, squeeze method
Extruded laminated metal composites can be divided into two categories: cladding materials and special laminated m-composite materials, and cladding materials can be divided into solid cladding materials and bimetallic tubes.
(1) extruded solid covering material.The most common type is the _ copper composite rod (titanium clad copper) of various shapes.
(2) extruded bimetallic tube.Two hollow billets are assembled before extruding: the billets are closed, and then extruded.Titanium/steel composite pipe section shape is round, square, drum;Shape, oblate, rectangle, etc.Diameter of circumferential circle: 4~80mm, thickness of cladding not 'J, not more than 0.8mm, length not more than 6n^ composite pipe has good technological performance, can achieve expansion, bend, neck and other further plastic processing.
