<p>This invention relates to glass filament production. Conventionally the hollow cooling tubes and/or solid metal bars utilized in the making of continuous glass fibers have been constructed of high temperature corrosion resistant materials whose costs are exorbitant for extensive present day factory operations. The present invention dramatically reduces the price of cooling tubes (24) suitable for use in the making of glass filaments by coating or cladding a relatively inexpensive base or substrate metal (48) such as nickel, Inconel, molybdenum copper, alloys thereof or a refractory material with a high temperature corrosion resistant material (50) such as the noble metals, e.g. platinum, palladium, rhodium, iridium, gold, silver or alloys thereof. Fins (52) which may be attached to the cooling tubes (24) may be made either of a solid noble metal or may also be coated or clad in the same manner as the cooling tubes (24). </p> |
