A thermal insulating layer is arranged inside an outer shell of a melting furnace, and the outer shell of the melting furnace is filled with liquid copper. A feed port is formed in the top of the melting furnace, and a liquid copper outlet is formed in one side of the melting furnace. A crystallizer is designed in the middle of a copper-clad aluminum rod crystallization device, an inner pipe is arranged in an outer pipe of the crystallizer in a sleeving mode, a liquid copper passage with even gaps is reversed between the inner pipe and the outer pipe, the bottom of the inner pipe is located in the middle of the outer pipe, and liquid copper inlets are formed in the upper ends of the gaps between the inner pipe and the outer pipe. The liquid copper inlets are connected with a liquid copper outlet of the melting furnace and are connected with the liquid copper passage. The upper portion of the outer pipe is covered with a liquid copper cooling jacket, and the lower portion of the outer pipe is covered with a liquid aluminum cooling jacket. The upper end of the crystallizer is provided with an aluminum rod tractor, and an aluminum rod penetrates through the aluminum rod tractor and is inserted into the inner pipe. The lower portion of the crystallizer is covered with a copper-clad aluminum rod tractor, and a cooled copper-clad aluminum rod penetrates through the copper-clad aluminum rod tractor. The copper-clad aluminum rod produced through the seamless copper-clad aluminum rod production device has the advantages that the outer layer copper wall is even in thickness, and copper and aluminum are combined in a seamless mode; in the process of use, the current loss is small and conductor quality is high.
Description
Technical field
The invention belongs to metal conducting bar technical field, relate to a kind of seamless copper cover aluminum bar process units.
Background technology
Conductive copper alclad bar is wrapped in interior a kind of electric conducting material with copper shell by seamless for aluminium core, it is kelvin effect when utilizing electric current to flow on conductor, most of electric current is allowed to flow in the conductive surface layers of copper that resistivity is less, fraction electric current flows at the conductor aluminium core that resistivity is slightly large, when reducing the current loss that electric conducting material causes as far as possible, substitute with aluminium core the manufacturing cost that copper core reduces conductor material.
In prior art, the manufacture of copper-clad aluminium conductive material, major part is in aluminium core outer wrap one deck layers of copper, the electric conducting material of this structure, because layers of copper and aluminium core cannot fit tightly, electric current is when flowing through the binding face of bi-material, the current loss produced is larger, because the layers of copper be wrapped on aluminium core has spiral overlap edge, surface copper layer thickness is uneven, causes current loss larger.
Summary of the invention
The object of this invention is to provide a kind of seamless copper cover aluminum bar process units, solve copper-clad aluminium conductive material exists in prior art layers of copper and aluminium core cannot fit tightly, the layers of copper be wrapped on aluminium core has spiral overlap edge, surface copper layer thickness is uneven, causes the problem that current loss is larger.
Technical scheme of the present invention is: seamless copper cover aluminum bar process units, is made up of melting furnace and copper cover aluminum bar crystallization apparatus, melting furnace shell built-in heat insulation layer, in-built copper liquid, melting furnace top is provided with charge door, and side arranges the outlet of copper liquid, the middle part of copper cover aluminum bar crystallization apparatus is designed with crystallizer, the outer tube inner sleeve of crystallizer has interior pipe, the copper liquid passage of gap uniformity is left between interior pipe and outer tube, be positioned at bottom interior pipe in the middle part of outer tube, the import of copper liquid is left in the upper end, gap left between inner and outer tubes, the import of copper liquid exports with the copper liquid of melting furnace and is connected, the import of copper liquid and copper liquid expanding channels, copper liquid coolant jacket is surrounded by the top of outer tube, aluminium liquid coolant jacket is surrounded by the bottom of outer tube, in the upper end of crystallizer, aluminium bar tractor is housed, aluminium bar is through aluminium bar tractor, in inserting in pipe, in the bottom of crystallizer, copper cover aluminum bar tractor is housed, cooled copper cover aluminum bar passes from copper cover aluminum bar tractor.
Its course of work is: first introduced in the copper liquid passage of crystallizer by the copper liquid melted in melting furnace, pass into circulating cooling liquid, make copper liquid be frozen into copper pipe at copper liquid passage hypomere in copper liquid coolant jacket; Simultaneously, utilize aluminium bar tractor the traction of aluminium bar to be entered in crystallizer to manage, control the chilling temperature of copper liquid coolant jacket in the process, make the solidifying point of temperature lower than copper of copper liquid passage in crystallizer, make the temperature in interior pipe higher than the fusing point of aluminium, after copper liquid is frozen into copper pipe, aluminium bar is melted into aluminium liquid in interior pipe, is full of by copper pipe inner chamber; When copper pipe is through crystallizer outer tube bottom, the aluminium liquid cooler being wrapped in outside pipe makes the aluminium liquid in copper pipe and copper pipe again cool, aluminium liquid is set in copper pipe center, form seamless combination with copper pipe inwall, the conducting rod after copper solidified aluminum combines is drawn by the copper cover aluminum bar tractor of crystallizer bottom.The gas produced in aluminium bar melting process, is discharged by the gap of interior pipe and aluminium bar contact-making surface, guarantees that aluminium liquid is when copper pipe solidified inside, reduce in the aluminium liquid solidified as far as possible and occur minute bubbles; The traction speed ratio of adjustment aluminium bar tractor and copper cover aluminum bar tractor, makes the aluminium liquid uniform filling copper pipe in copper pipe.
The copper cover aluminum bar utilizing the present invention to produce, outer copper wall thickness is even, and copper and aluminum seamless combine, and during use, current loss is less, and conductor quality is higher.
