Ld-Steel converter having a refractory lining containing a gas-transmitting bottom element.

摘要

A gas-transmitting wall element for a metallurgical vessel having a refractory lining is described which is subject to low wear, is reproducible and makes unnecessary continuous blowing of gas through it. The element has an outer sheet metal box (1), open at one end, and a refractory filling (2) in the box comprising at least one brick spaced from the closed end (4) of the box, into which a gas inlet (3) opens. The brick contacts the metal sidewalls of the box and has grooves (7) to allow the gas to pass to the open end of the box.
