Tundish Nozzles, Exchangeable Systems & Three-Plate Gates
Integrated refractory solutions for controlling molten-steel discharge from the tundish into continuous-casting equipment, including metering nozzles, exchangeable nozzle assemblies, well blocks, upper and lower nozzles, and three-plate gate systems.
Product Diagram, System Types and Published Benefits
The supplied catalogue image is presented as the central technical reference. The structured sections below separate the three systems, their components and their principal operational benefits.
Three Tundish Flow-Control Arrangements
Each arrangement controls molten steel differently and should be selected according to casting practice, required flexibility, safety considerations and equipment design.
Metering Nozzle
A fixed-orifice refractory nozzle, typically incorporating an internal zirconia insert within an alumina-graphite body, regulates flow through its bore diameter.
Exchangeable Nozzle System
A fixed upper outlet element transfers molten steel to a replaceable lower nozzle, allowing the lower flow-control component to be changed during the casting campaign.
Three-Plate Gate System
A movable middle plate changes the overlap between the openings of stationary upper and lower plates, providing adjustable flow control and shut-off capability.
Main Refractory Components Grouped by System
Grouping the components under their corresponding systems makes the diagram easier to interpret and avoids presenting unrelated product cards without context.
Metering-Nozzle Arrangement
Fixed-orifice regulation of the tundish discharge rate.
Exchangeable Nozzle Arrangement
Modular upper and lower outlet components for flexible operation.
Three-Plate Gate Arrangement
Adjustable refractory plate assembly for regulating or stopping flow.
