Abstract

An article and processes are described for manufacturing a metallurgical pour tube for use in the continuous casting of steel. The article has an erosion-resistant sleeve within a body of the pour tube. An accommodation region allowing for thermal expansion of the sleeve is disposed between the sleeve and the body. The region comprises a gap or a compressible material. As the pour tube is brought to casting temperatures, the region permits the sleeve to expand without fracturing the body of the pour tube. The article may be formed by several processes. A first process describes placing a pre-formed sleeve coated with a spacer material in a body mix and firing the article to form an accommodation region. A second process comprises injecting an erosion-resistant refractory mix into a cavity within the body and firing the article. A third process secures a sleeve within an accommodation region formed by mechanically securing a third component to the body of the pour tube. A fourth process describes using a guide means to segregate a body mix, an erosion-resistant material, and a spacer material, whereby firing produces an erosion-resistant sleeve and an accommodation region within a pour tube body.
