Cooled tubular element for metallurgical furnace - has two straight tubular portions with coaxial inserts whose cross=sections decrease in flow direction of cooling medium

摘要

Cooling pipe elements for a metallurgical furnace consist of lengths of pipe fitted with an internal core whose diameter gradually reduces in the direction of flow of the cooling medium. Sections of pipe can be joined where the pipe and core diameters are compatible with the core joint having a tongue and groove configuration. The cooling pipes so designed have dimensional relationships which give more efficient cooling, better functional reliability, longer working life, reduced usage of metal in their production and a simpler production method for bent pipe elements.
