Mononozzle

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.

Safety Blank Plate

Blind sliding-gate-type plate used in emergency, and at the end of cast, to stem the flow of steel from the mononozzle.

Preheat

Sliding-gate-type plate with a hole the same diameter as the mononozzle, used for setting-up the tube change mechanism and, if appropriate, preheating the nozzle well area and stopper with a vertically firing burner.

Bubbler Housing & Well Blocks

High wear-resistant pre-cast product that manages localised turbulence and maintains uniform dimensional control, enabling seating of the purge plug.

Ladle Upper Nozzle

Part of the ladle gate system mounted into the Well Block above the lower nozzle (alternatively upper & lower sometimes as one piece).

Purge Plug

Enables the introduction of purging gas through a heat of molten metal in a ladle.

Tundish Furniture

Controls the flow of molten metal, reducing splashing and impurities.

Tundish Bubbler

Porous “brick” used to provide a curtain of argon across the width of the tundish to aid flotation of inclusions.

Temperature Probe Housing Block

Fired pre-cast products used to house continuous temperature measuring systems.

Composite Lance

Injection lance enabling sections to be added during use.

Injection Lance

Refractory coated steel pipe used to inject gas (oxygen or inert depending upon application), into steel in the ladle or converter.

Top Support Ring

Pre-cast product giving extra security and support to the Tundish Mononozzle during casting.

Fired Ceramic Nozzles

Typically used in gas supply and burner arrangements.
