This invention discloses a method for preparing tungsten wire and the tungsten wire itself. The method involves first forging and drawing a tungsten alloy, then drawing the tungsten wire in a wire drawing machine containing a two-stage natural gas heating tank. When the diameter is 1.4 ≤ R ≤ 2.3 mm, the first stage natural gas to air flow rate ratio is 0.2R cubic meters: 3(R+0.1) cubic meters, and the second stage natural gas to air flow rate ratio is 0.5R cubic meters: 6(R+0.1) cubic meters. When the diameter is 0.77 ≤ R < 1.4 mm, the first stage natural gas... The first stage of natural gas to air flow ratio is 0.18R:3R, and the second stage ratio is 0.45R:5(R+0.2). When the diameter is 0.35≤R<0.77mm, the first stage ratio is 0.15R:2.5(R+0.05), and the second stage ratio is 0.42R:4.5(R+0.25). The resulting tungsten wire is then heated in an electric furnace and drawn in multiple passes to produce fine tungsten wires with a diameter of 0.0630–0.0660mm. This invention reduces the natural gas to air flow ratio while decreasing the wire diameter, thus maximizing natural gas utilization while maintaining the heating temperature.
