Abstract

An immersion pouring spout for introducing molten metal, such as steel, into an ingot mold is provided with a top head and a cylindrical pouring tube including a protective external jacket attached by cement to the pouring tube and extending the entire length of the pouring tube. The jacket material has a thermal conductivity that is less than the thermal conductivity of the pouring tube material.
