The present invention relates to the preparation method of a kind of copper base used for coating conductor/long base band of Ni-based compound, described long base band is the sandwich structure of sandwich, and intermediate layer is NiW alloy, and two skins are CuNi alloy, and it is characterized in that, its step comprises as follows:
(1), by smelting process obtain NiW alloy billet, then after high temperature forge hot and descale cutting process to obtain 3-5cm thick, 5-10cm is wide, and length is the alloy block of 20-30cm;
(2) after, NiW alloy block being inserted the groove of mould intracavity bottom, make the right two sides of NiW alloy phase parallel with dies cavity wall and have space, the CuNi alloy-layer that moulding by casting fusing point is lower in a mold under vacuum or reducing atmosphere protection, the original long strip type compound billet of acquisition; Wherein the thickness proportion of NiW alloy and CuNi alloy individual layer is preferably 1:1.
(3) carry out hot rolling cogging after the long strip type compound billet homogenizing heat treatment, to step (2) obtained, passage type variable is 15-30%, and total type variable is greater than 50%, and temperature is 800-1000 DEG C.
(4), finally carry out cold rolling, trimming and the high temperature anneal obtain texture content more than 98% the long base band of compound, high annealing is 800-1000 DEG C.
Above-mentioned dies cavity is square cavities, and is provided with a groove in the middle of intracavity bottom, the length of preferred groove is equal with the length of inner chamber, and preferred mold has identical two to be semifixedly spliced.
Adopt method of the present invention can prepare the long base band of 100 meter level compound.Composite baseband prepared by this method have highly-textured, without features such as ferromagnetism and good mechanical performances, and cost is low, operation is simple, is more suitable for suitability for industrialized production.
