Upper Nozzle & Lower Nozzle
Precise steel flow control, ensuring steel purity
Upper Nozzle & Lower Nozzle
Long Service Life
High-quality refractories with optimized formulations and processes reduce replacement frequency and extend service life.
High Performance
Excellent refractoriness, strong thermal shock resistance, and corrosion resistance effectively resist molten steel and slag attack.
Stable Steel Tapping
High dimensional accuracy ensures smooth operation with slide gate mechanisms.
Ensured Steel Quality
Optimized bore design reduces slag entrapment and improves steel purity.
