The application discloses a pouring system for large castings, comprising: a pouring cup for conveying molten metal, a runner assembly is installed at the lower end of the pouring cup; and several sets of slag collecting devices for collecting metal slag. The pouring system of a large casting of the present invention adopts a multi-stage slag collecting bag structure. After the molten metal rushes into the inner runner from the sprue, it passes through the first-stage slag collecting bag, and most of the metal slag is blocked here. After the excess metal slag passes through the subsequent multi-stage slag collecting bag, the metal slag is blocked in the slag collecting bag, and the metal slag will not enter the casting with the molten metal, and no casting defects will be formed. Better, the height of the inner runner is different, and the molten metal moves along the inner runner and the slag collecting bag to reduce the direct impact of the molten metal on the inner gate, so that the molten metal flows smoothly, and the horn-shaped inner gate reduces the splash of the molten metal and prevents castings. Defects occur, further improve the quality of the product and bring better prospects for use.
