Abstract
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, open at one end, and a refractory filling in the box comprising at least one brick spaced from the closed end of the box, into which a gas inlet opens. The brick contacts the metal sidewalls of the box and has grooves to allow the gas to pass to the open end of the box.

Gas-transmitting wall element for a converter for steel making having a refractory lining composed of bricks, the element comprising a metal box having a base and side walls, a gas inlet opening in said box adjacent said base and a refractory filling in said box composed of at least one refractory element, said refractory element being an unfired pressure moulded brick made of refractory particles and binder, the filling being spaced from the said base of the box and having faces contacting the side walls of the box and grooves in said faces for passage of the gas extending from the end of the element(s) adjacent the base to the opposite end thereof, said wall element having the same shape as one or more bricks in the region of the lining adjacent the wall element.
A converter for steel making having a refractory lining composed of bricks and, in the lining, at least one wall element comprising a metal box having a base and side walls, a gas inlet opening in said box adjacent said base and a refractory filling in said box composed of at least one refractory element, said refractory element being an unfired pressure moulded brick made of refractory particles and binder, the filling being spaced from the said base of the box and having faces contacting the side walls of the box and grooves in said faces for passage of the gas extending from the end of the element(s) adjacent the base to the opposite end thereof, said wall element having the same shape as one or more bricks in the region of the lining adjacent the wall element arranged for direct supply, in use, of gas into a molten metal bath in the vessel.
