Abstract
A refractory gas-permeable structural unit for blowing a gas into a metal treatment vessel and through its casing has at least two elements composed of refractory material and having abutting longitudinal faces provided with at least one metal layer, a metal housing surrounding the elements to connect them with one another and tightly abutting against other longitudinal faces of the elements, and a gas distribution chamber formed at an end face of the elements and communicating with a gas supply conduit.
Claims26
A refractory gas-permeable structural unit for blowing a gas into a metal treatment vessel and through its casing, characterized by a passageway formed by faces of at least two elongated refractory elements, said elements being separated from one another by a thin metal layer so that gas passage takes place between said elements along said metallic layer, said elements each having first and second longitudinal faces and hot and cold end faces, said metallic layer being arranged on the first longitudinal face of at least one of said elements;
- a metal housing surrounding said elements to connect them with one another and sealingly abutting against said second longitudinal faces of said elements;
- and means for supplying gas and including a gas distribution chamber formed at said first end faces of said elements and a conduit communicating with said distribution chamber.
