Abstract
PURPOSE: To perfectly protect a wire of a high m.p. metal such as W from quality deterioration due to carbon contamination by heating the wire to form oxides on the surface, which oxides carbon adhered to CO or CO2, followed by introduction into a hydrogen furnace.
CONSTITUTION: Prior to forming a wire of a high m.p. metal such as W into a coil shape, carbon adhered is revoved to prevent contamination as follows: W wire 2 is heated to 600W1000°C with gas burners 3,3 to form lower grade oxides such as W2O3 and W4O11 on the surface. The oxides react with carbon adhered to bind the carbon in the form of CO CO2. Wire 2 then enters hydrogen furnace 1, where the above various oxides are reacted and removed easily.Accordingly, the resulting W wire coils are not contaminated with carbon, off-grade goods due to a lowering of tensile strength are reduced, and product yield is enhanced.
