▎ 摘  要

NOVELTY - Preparation of high infiltration rate copper infiltrated wire involves mixing nickel, manganese, iron, zinc, and copper obtain mixture, adding mixture into crucible of vacuum melting furnace, heat preserving to obtain an alloy solution, casting out of the furnace to clean the surface of the mold without impurities and oil adhesion, and then demolding after cooling to obtain an alloy ingot, forging and turning the outer circle of the alloy ingots to obtain an alloy bar, hot rolling and coiling the alloy bar to primary alloy wire, and then placing the primary alloy wire on the coiling machine through multiple passes to obtain copper infiltrated wire and annealing the copper infiltrated wire during the drawing process, and cutting and slitting the alloy wire according to the required length. USE - Preparation of high infiltration rate copper infiltrated wire. ADVANTAGE - The method is inexpensive, and enables preparation of high infiltration rate copper infiltrated wire with excellent permeability. DETAILED DESCRIPTION - Preparation of high infiltration rate copper infiltrated wire involves mixing 0.05-0.5 wt.% nickel, 0.1-1 wt.% manganese, 1-3 wt.% iron, 1-5 wt.% zinc, and the balance of copper for 15-35 minutes to obtain a mixture, adding the mixture into the crucible of the vacuum melting furnace, and then pumping the vacuum in the vacuum melting furnace to 3-6x 103 Pa, controlling the melting current to 1200-1600 A, and melting power to 5-8KW, then refining at 1250-1280 degrees C for 10-20 minutes, heat preserving for 5-15 minutes to obtain an alloy solution, casting out of the furnace to clean the surface of the mold without impurities and oil adhesion, and then preheating the runner with ceramic filter plate to 1100-1300 degrees C, and finally pouring the alloy solution into the runner, absorbing the impurities in the ceramics, filtering into the mold, and then demolding after cooling to obtain an alloy ingot, where the casting speed is initially slow and then speed up, and finally slow down, forging and turning the outer circle of the alloy ingots heated to 910-950 degrees C in an electric furnace for 2-3 hours, then placing in a forging die for forging to form a phi 30-40 mm bar, and removing the oxide scale on the surface of the bar to obtain an alloy bar, hot rolling and coiling the alloy bar to 850-880 degrees C after holding for 0.5-1.2 hours, rolling on a planetary rolling mill at a hot rolling speed of 50-80 m/minute to phi 8-12 mm primary alloy wire, and then placing the primary alloy wire on the coiling machine to be coiled into 15-45 m/reel coils, drawing, annealing, the disc round material drawn on a disc drawing machine in multiple passes at a drawing speed of 0.5-2.5 m/minute, and a deformation rate in a single pass is 4-8% to obtain phi 1-3 mm copper infiltrated wire and annealing the copper infiltrated wire at 500-550 degrees C during the drawing process, and cutting and slitting the alloy wire according to the required length.
