MOLTEN-METAL SUPPLY PIPE FOR MOLTEN METAL
PROBLEM TO BE SOLVED: To provide a ceramic molten-metal supply pipe for molten metal capable of restraining generation of a pore and a defect in a casting.SOLUTION: A molten metal supply pipe for molten metal of the present invention, is the molten-metal supply pipe for molten metal for supplying the molten metal to nonferrous metal casting equipment for connecting an end part of a plurality of ceramic pipes, and in the molten-metal supply pipe for molten metal, a downstream side pipe 12 arranged on the downstream side for circulating the molten metal, has a taper part 5 in an upstream side end part 4 of an inner diameter, and an opening diameter D15 on the upstream side of the downstream side pipe 12 is larger than an opening diameter D5 on the downstream side of an upstream side pipe 2 arranged on the upstream side for circulating the molten metal. In the molten-metal supply pipe for molten metal, the upstream-downstream side pipes 2 and 12 are constituted of a silicon nitride sintered body.SELECTED DRAWING: Figure 3
【課題】鋳造品で巣や欠陥の生成を抑制できるセラミックス製の溶湯用給湯管の提供。【解決手段】本発明の溶湯用給湯管は、複数のセラミックス製管の端部を接続した非鉄金属の鋳造設備に溶湯を供給するための溶湯用給湯管であって、溶湯が流通する下流側に配置された下流側管12は内径の上流側端部４にテーパ部5を有し、下流側管１２の上流側の開口径D15は、溶湯が流通する上流側に配置された上流側管2の下流側の開口径D5より大きい溶湯用給湯管。上・下流側管２，１２は、窒化珪素焼結体で構成されている溶湯用給湯管。【選択図】図３
