PURPOSE:To obtain a roughly drawn wire at a low cost without using any nozzle by sticking molten metal continuously on the surface of a base core wire of a helical coil shape which is rotated and moved from the opening above a crucible while part thereof is immersed in the molten metal. CONSTITUTION:While the above-described base core wire 12 is held immersed of a part of its coil part 12A in molten metal 2, it is held by each of pinch rolls 13, 13 and 13', 13'. An intermediate winding drum 15 is rotated to apply proper tension upon the wire 12, and the wire 12 is rotated overall by means of the above-mentioned pich rolls. While the respective coil parts 12A are immersed successively partly in the metal 2, the wire is moved in an arrow direction. The metal 2 is solidified and stuck successively on the peripheral surface of the wire 12, to make a cast rod 14 of a helical coil shape. Such rod is conducted via rolls 13', 13' to the drum 15, on which it is coiled. The lot 14 of such rod is supplied to a hot working machine 6, by which it is drawn to a roughly drawn wire 7. The wire is fed into the next stage. The remaining lot 14 is recirculated as the wire 12 like in the prior art. |
