The present application discloses a pouring system for large castings, including: a pouring cup for conveying molten metal, a pouring runner assembly being installed at the lower end of the pouring cup; and several groups of slag collecting devices for collecting metal slag. The pouring system for large castings of the present invention adopts a multi-level slag collecting bag structure. After the molten metal rushes into the entgate from the straight runner, it passes through the first-level slag collecting bag, and most of the metal slag is blocked here. After the excess metal slag passes through the subsequent multi-level slag collecting bags, the metal slag is blocked in the slag collecting bag. The metal slag will not enter the interior of the casting with the molten metal, and will not form casting defects. The quality of the manufactured product is better. The entgate has different heights, and the molten metal moves along the entgate and the slag collecting bag in a curved manner, which reduces the direct impact of the molten metal on the entgate, making the molten metal flow smoothly. The trumpet-shaped entgate reduces the splashing of the molten metal, prevents the occurrence of casting defects, further improves the quality of the product, and brings better prospects for use.
