description The utility model discloses a pouring pipe with a smooth inner wall, which comprises a pipe body. A pipe wall of the pipe body consists of five layers, the two inner layers are zircon layers or white corundum layers, and the three outer layers are mullite layers. The pouring pipe has the advantages of ultra-smooth inner wall, low resistance, high refractoriness, molten metal scouring resistance and molten metal erosion resistance, zero water content and the like, and is a best pouring pipe for improving internal quality of casting.
