PURPOSE:To manufacture a high quality composite mateial continuously at high speed, by coating a core material with metallic powder softer than a core material under the specified conditions in the inside of a cylindrical body of a drawing die consisting of two working parts having a small die angle and a die angle larger than the former respectively. CONSTITUTION:A steel wire 2 supplied from a feeding drum 1 is passed through a polishing device 3, a cleaning device 4, an electrically heating roll 5, and an oxidation-protecting and heat-insulating cylinder 7, and is fed into a drawing die 9 provided with supersonic wave by a supersonic wave oscillator 8. Powdered Al 15, for example, is supplied to the die 9, and when the wire 2 is pulled by a take-up capstan 12 at >=10m/min drawing speed, the powder 15 address on the circumference of the wire 2, and an aluminum coated steel wire 10 which is a composite material is manufactured. Then, the wire 10 is coiled up after it has been passed through a cooling device 11. In this case, the die 9 consists of two dies having cylindrical bodies respectively, which consists of a die 13, inducing part having a die angle of 0-10 deg. whole angle and a die 14 having a die angle of 5-30 deg. whole angle, and performs a press-forming of the powder 15 under the action of supersonic wave. |
