Abstract

1. Refractory gas-permeable structural unit (1) for blowing gas into a metallurgical vessel through its lining, comprising at least two elements (3, 23, 33, 43, 53, 63) having a core of refractory non-porous material (9, 29, 39, 49, 59, 69), said elements abutting against one another with their longitudinal faces, a common metal housing (10) surrounding the longitudinal faces of said elements with at one of the end faces of the unit (1), at least one gas connection (8) and a gas distribution chamber, characterized in that the elements are provided at least on all their longitudinal faces with a gas-tight cover.
