Submerged Nozzle for Continuous Casting

Protect the molten steel from oxidation when it flows into the crystallizer from the tundish, evenly distribute the molten steel into the crystallizer, and control the flow state of the molten steel in the crystallizer, with good slag resistance, anti-blocking, uzoq xizmat muddati, and low accident rate.
