Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a pouring device for reducing internal pores of a casting. Background Art

[0002] During the casting process, air will be drawn into the molten steel. The molten steel has no time to be discharged before solidification and remains in the casting to form pores. The pores are large in size and smooth inside. They are concentrated on the upper surface of the casting, causing the casting to be scrapped after processing.

[0003] According to the search, Chinese patent literature, announcement number: CN217570761U, discloses a pouring device for reducing casting pores. This solution arranges a plug rod in a square pouring cup, and uses the plug rod to block the vertical runner, so as to facilitate pouring a certain height of molten metal into the square pouring cup, discharge air in advance, increase the static pressure of the molten metal, avoid the turbulence of the molten steel during pouring and bring in gas, reduce the impact of the molten metal on the shell, avoid the formation of pores in the casting, improve the quality of the casting, and reduce the scrap rate of the casting.
