Two-Phase Flow in Tundish Nozzles During Continuous

 · Tundish nozzle geometry is one of the few variables that are both very influential on the castingprocess and relatively inexpensive to change. Designing an effective nozzle requires quantitativeknowledge of the relationship between nozzle geometry and other process variables on theinfluential characteristics of the flow exiting the nozzle. This relationship depends on the flowpattern within the nozzle components. Most previous modeling studies of flow in the nozzle havefocused on single-phase flow 1-4 . Argon injection into nozzle is an efficient and widelyemployed method to reduce nozzle clogging even though the real working mechanism(s) are stillnot fully understood. Argon injection may greatly affect the flow pattern in the nozzle andsubsequently in the mold. Therefore two-phase flow modeling is needed to improveunderstanding of fluid flow in the nozzle.

The lower nozzle is located within an assembly that is fixed to the bottom of the Tundish. Once the nozzle wears out or the casting speed needs to be reduced the lower nozzle can be exchanged with either a new lower nozzle or a blank nozzle to shut the strand off entirely. Lower nozzles must be erosion resistant to enable long casting sequences.

Mechanism of alumina buildup in tundish nozzles during

During continuous casting of aluminum-killed steels the pouring rate through the tundish nozzle often diminishes posing serious operating problems. This happens because a build- up of microscopic alumina particles at the nozzle orifice effectively decreases the nozzle orifice diameter and causes constriction of the liquid-steel pouring stream
