BUSH FOR APPARATUS PRODUCING CAST ROD BY DIP CASTING FROM CORE-WIRE

摘要

There is disclosed a bushing for use in an apparatus for continuously passing a core wire through a crucible holding molten metal to accrete the molten metal on the core wire to form a cast rod. The bushing is connected to the crucible for passing the core wire therethrough into the crucible. The bushing is tubular and has an engaging portion for engaging with the core wire passing therethrough. The engaging portion is made of ceramics material containing a major proportion of at least one selected from the group consisting of zirconia, silicon carbide and silicon nitride.
