Description
Technical field
The utility model is related to the production equipments that a kind of long length large-diameter and high-strength height leads NEW TYPE OF COMPOSITE wire rod.
Background technology
With the development of electronic information technology, higher and higher to the requirement of the synthesis performance of copper alloy conductive material, it
It is asked to keep high intensity（Hardness）, toughness, wearability while, still keep higher electric conductivity, thermal conductivity, cold resistance, nothing
The characteristics such as ferromagnetism.These excellent characteristics make copper alloy be increasingly becoming electric power, information, traffic, the energy, light industry and space flight boat
The important meals material used in the high-tech areas such as sky.Many occasion applications seldom in the form of fine copper, this is because fine copper
Intensity it is relatively low (230~300 MPa), although can reach 400 MPa after cold working, elongation is only 2%, heating or
In use, its reinforcing effect is easy to disappear under certain temperature.So fine copper be applicable only to the little electric power of stress, electric appliance,
Electric conductor, radiator, decoration of electronics etc..Under the premise of keeping some excellent performances of fine copper, copper is improved as far as possible
Intensity (hardness) and wearability, immediately high-strength high-conductive copper alloy be gradually developed.
High-speed electric railway uses Cu-Mg, Cu-Sn alloyed contact line at present, such wire rod is to lose conductivity
Premised on.Cu-Cr-Zr contact lines also locate laboratory stage or small lot experimental stage, though have centainly what original base stopped
The raising of amplitude, but increase rate is limited, and the production of NEW TYPE OF COMPOSITE wire rod is led using a kind of long length large-diameter and high-strength height
The wire rod of equipment and its technique productions can greatly enhance the tensile strength of wire rod, and keep higher conductivity, overcome this
Class other alloy materials production control is difficult, of high cost, produces the difficult points such as unstable quality in enormous quantities, has both high safety factor,
The characteristics of high-tensile and high conductivity, meets the following high-speed railway wire rod demand for development.

Exhibition needs, and major technique equipment reaches or approaches advanced international standards.
Long length major diameter high-strength highly-conductive NEW TYPE OF COMPOSITE wire rod can not only meet the single products such as electric railway contact line
Weight is more than 1 ton of requirement, solves the significant technology issues of puzzlement domestic pharmaceutical industry industry, has great commercial introduction value, fills out
A blank for mending the domestic advanced composite material (ACM) production technology, for pushing the technological progress and autonomous innovation of Copper fabrication industry
The construction of ability has immeasurable realistic meaning.
The raising of contact line intensity will provide safer broader space for China express railway centenary design.
The promotion of electric conductivity can also save a large amount of electric energy.It will will produce accordingly in production, experiment, construction, operation etc. simultaneously
Autonomous innovation scientific achievement is greatly promoted the development of China's high speed contact network technology.New-product development has been greatly facilitated dress
The progress of standby technology, the producing equipment of factory are upgraded, and whole production level is improved.
However, traditional contact line mode of production production cycle is long, due to being a stove one casting, length weight and shape all by
To limitation, and vacuum production cost is high, yield is small, it is difficult to establish serialization commercial production scale.
Invention content
In view of the above technical problems, the setting time that the utility model passes through the dead weight and control mixed liquor of vertical mixed liquor
And speed, the thickness of Copper steel cladding layer can be adjusted, strengthen the firmness, conjugation and integraty of composite wire, copper, steel line
Expansion factor can be ignored so that copper and steel will not be detached from because of the line expansion factor of copper and steel.Meanwhile during the drawing process
The different deformation amount for solving the problems, such as copper and steel realizes long length major diameter continuous casting and even pulls out.
The utility model provides the production equipment that a kind of long length large-diameter and high-strength height leads NEW TYPE OF COMPOSITE wire rod, including

Steel copper composite layer and steel core, outer mold closing in an inverted cone arrange mold in port connection contact line molding, and discharging is molded,
Long length novel high-strength height is prepared and leads Copper steel cladding contact line.
Further, big by the setting time of control steel copper mixed liquor and the interfacial thickness of speed control steel copper composite layer
It is small.Control Copper steel cladding contact line discharging 2 ± 0.5m/min of speed to control the time that copper water and molten steel are mutually mutually mixed,
Can control in this way molten steel can with melting copper number, the speed 3-5L/ of 3-10 DEG C of the initial temperature and flowing of control loop cooling water
Min, the time that setting rate and copper steel mixed interface to control molten steel solidify, to control the thickness of copper steel mixed interface
Degree.Copper steel cladding layer can by one entirety of highly conductive organic formation of the high intensity of steel and copper, can mutually it is complementary long take it is short,
Play respective advantage.
Further, according to the degree of copper and steel solidification, volume-diminished, the angle of outer mold back taper is determined.Due to copper
Steel can receive it in solidification and contract, therefore there are small spaces with outer mold for copper, and the angle of back taper is about between 0.2 to 1 degree.
When molten steel from inner mould tube inlet inject, from inner mould pipe outlet enter solidification copper or copper alloy tube,
At this point, since the temperature of molten steel is up to 1800 DEG C（1083 DEG C of the molten point of copper, 1515 DEG C of the molten point of steel）, can be by the copper or copper of solidification
The tube wall of compo pipe melts, and forms steel and copper mixed liquor, and steel copper mixed liquor is uniform under the action of the vortex that hot-wire coil generates
Distribution, with the effect of cooling system, mixed liquor and the movement of molten steel downward spiral are gradually frozen into solid, and outer mold is at back taper
Shape closes up（It is solidified according to copper and steel, the degree of volume-diminished determines the angle of outer mold back taper）, contact line is connected in port
Molding arranges mold, and discharging molding is prepared long length novel high-strength height and leads Copper steel cladding contact line.
