Zusammenfassung: | To provide a molten metal pouring apparatus capable of attaining the improvement of the quality of a cast and productivity by increasing a flow rate of a molten metal.SOLUTION: A molten metal pouring apparatus 1 comprises: a chute 2 to which a molten metal M1 is poured; and a trough 3 in which a base end part is connected to the chute 2 to introduce the molten metal M1 into a cylindrical mold 200. The trough 3 has: a metallic tube 30; and a ceramic tube 40 internally fitted into the metallic tube 30. The chute 2 has: a body part 10 diameter-reduced to a direction in which the molten metal M1 flows so as to be fixed to the metallic tube 30; and an inner wall part 20 made of a refractory formed at an inside face of the body part 10. A surface of the inner wall part 20 is formed so as to be continuous to an inside face of the ceramic tube 40.SELECTED DRAWING: Figure 2A
【課題】溶湯の流量を大きくして、鋳物の品質及び生産性の向上を図ることができる注湯装置を提供する。【解決手段】溶湯M1が注ぎ込まれるシュート2及びシュート2に基端部が接続されて溶湯M1を円筒状金型200へ導くトラフ3を備える注湯装置1であって、トラフ3は、金属管30及び金属管30に内嵌されるセラミック管40を有し、シュート2は、溶湯M1の流れる向きに縮径して金属管30に固定される本体部10及び本体部10の内側面に形成される耐火材からなる内壁部20を有し、内壁部20の表面は、セラミック管40の内側面に連続するように形成されている。【選択図】図2A |
