A combination of tundish nozzle and sliding-gate-type stationary plate as one item, through which steel pours from tundish to mould, and the sliding surface of which facilitates the tube change. All mononozzles have argon protection to the sliding surface and the majority have argon supply to the stopper seating area, although “solid” nozzles are available for use with e.g. CaSi treated steels if necessary.
Blind sliding-gate-type plate used in emergency, and at the end of cast, to stem the flow of steel from the mononozzle.
High wear-resistant pre-cast product that manages localised turbulence and maintains uniform dimensional control, enabling seating of the purge plug.
Part of the ladle gate system mounted into the Well Block above the lower nozzle (alternatively upper & lower sometimes as one piece).
Porous “brick” used to provide a curtain of argon across the width of the tundish to aid flotation of inclusions.
Refractory coated steel pipe used to inject gas (oxygen or inert depending upon application), into steel in the ladle or converter.
