Furnace Nose

Core Function: As a critical gas-tight connection between the annealing furnace and zinc pot in galvanizing lines, it employs special sealing structures and controlled protective atmosphere to prevent oxygen ingress, ensuring the strip enters the zinc pot under oxidation-free conditions. It is the core component for achieving high-quality galvanized surfaces and stable production processes.
