Abstract

A steel pipe (2) as a cooling pipe is cast in copper or copper alloy casting that forms a stave body (1). The outer surface of the steel pipe (2) is chromium-or nickel-plated. The steel pipe (2) is made of austenite-based stainless steel. The copper purity of the stave body (1) is at least 99.9%. An outer pipe (3) is provided at the junction between the steel pipe (2) and the stave body (1) to provide a double-pipe structure. The projecting portion of the steel pipe (2) projects outward beyond a seal member (6) on the outer side of a shell (4).
