Abstract
The invention discloses a small-investment and simple process for the semi-solid state continuous forming of a heavy cross section conducting copper-clad aluminum wire, which comprises the following steps: cladding a brushed aluminum wire with a brushed copper strip and welding a joint close formed in cladding; drawing a copper-clad aluminum blank, heating the drawn cooper-clad aluminum blank, and controlling a heating temperature between 660 and 680 DEG C and the heating time between 10 and 20 seconds; placing the heated cooper-clad aluminum blank in cold water for cooling; and drawing the cooled cooper-clad aluminum wire to make a finished product of the cooper-clad aluminum wire. The process of the invention is simple in course and low in corresponding equipment investment and has an excellent development prospect.
Description
Technical field
The present invention relates to the continuous forming process of copper cover aluminum, refer more particularly to process for semi-solid state continuous forming of heavy cross section conducting copper-clad aluminum wire.
Background technology
At present, the production of copper cover aluminum composite material and processing method, can be divided into " Gu-solid phase composite algorithm " and " liquid-solid phase composite algorithm " substantially, the former mainly comprises: rolling compound, blast is compound, the extruding drawing is compound etc., the latter mainly refers to fill out core continuous casting composite algorithm and quiet liquid extrusion.
Filling out core continuous casting composite algorithm and be a kind of being used to prepares the NEW TYPE OF COMPOSITE technology that refractory metal coats low-melting-point metal, is filling core metal liquid and make it to solidify in continuous casting outer layer metal shell, to realize the compound of two kinds of metals.University of Science ﹠ Technology, Beijing thanks to build and newly waits the people to invent a kind of high-performance cooper-coated aluminum rectangle section compound conductive bus row and preparation technology thereof.Cooper-coated aluminum rectangle section compound conductive bus bar is composited by core aluminium and coating layer copper, and coating the long-pending ratio of copper aspect is 15～50%, the steps include: to adopt the direct composite forming copper cladding aluminum composite blank of horizontal casting; With the finishing drawing again of the common as required flat rolling of copper cover aluminum blank, or adopt the flat rolling of being with edger roll, the mill speed scope is 3～50m/min, and the single pass relative reduction is 15～40%; The finishing drawing velocity interval is 1～20m/min, and single pass cross section economy is 10～25%; Reach at 70～90% o'clock in the rolling total relative reduction of multi-pass, the copper cover aluminum compound conductive bus bar is carried out low temperature intermediate annealing, annealing temperature is 250～450 ℃, and annealing time is 0.5～3h; Compound conductive bus bar after the annealing is carried out groove rolling or drawing.This technology is very complicated, and does not obtain practical application.
And for heavy in section copper cover aluminum busbar, main " the quiet liquid extrusion " production technology that adopts.This production technology applies very high hydrostatic pressure by liquid medium to moulding material and impels its interface compound, and the minimum a kind of solid-state complex method of frictional resistance.This production technology is quite ripe at present, and still, this technology devices needed investment is huge, and the technology more complicated, and technological process is longer, and production efficiency is lower.All these makes production cost bigger, thereby has caused the price of the heavy in section copper cover aluminum busbar finished product produced higher.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of investment is little, the simple process for semi-solid state continuous forming of heavy cross section conducting copper-clad aluminum wire of technology.
For solving the problems of the technologies described above, the technical solution used in the present invention is: process for semi-solid state continuous forming of heavy cross section conducting copper-clad aluminum wire, the steps include: and to coat with copper strips through the aluminium row of scratch brushing through scratch brushing, and the joint close that coating is formed welds, then, the copper cover aluminum blank is stretched, heat after stretching, the temperature of heating is controlled between 660～680 ℃, time was controlled between 10～20 seconds, then, put into cold water and cooled off, at last, cooled copper clad aluminum wire is drawn into the copper clad aluminum wire finished product.
The joint close that described coating forms is positioned at a side of the short rectangular edges of aluminium row.
The invention has the beneficial effects as follows: technical process of the present invention is shorter, production efficiency is higher, and, the corresponding apparatus investment is also little, thereby reduced production cost, reduced the price of finished product, and made copper strips and aluminium arrange one integrated mass, improve the quality of copper clad aluminum wire greatly, had bright development prospect.
