Subentry Nozzle
Subentry Nozzles have different slag line and seating materials customized to any steel grade and casting speed. There is a choice of liner material for the internal bore, all aimed to reduce alumina build-up. A range of coatings are available to preserve the refractory in prime condition during the preheat stage.
Composite Seating material.
High alumina or high magnesia. For more extreme casting conditions, ultra-low carbon alumina or magnesia liner material can be applied.
Anti-alumina Build-up Liner.
Preventing alumina clogging.
Body material.
Alumina graphite material with additional elements to provide required field performance.
Slagline flux resistant composite sleeve.
Based on zirconia material.
Protective coating system.
They protect the graphite based material from oxidation during pre-heat and casting.
Insulation fiber or coating
To preserve heat during off-gas period.
