Submerged nozzle
The submerged nozzle plays the role of protecting the molten steel from being oxidized by ambient air when it flows into the crystallizer from the tundish, and at the same time, it also plays the role of evenly distributing the molten steel to the crystallizer and controlling the flow state of the molten steel in the crystallizer. Because of its excellent performance such as good slag resistance, blockage prevention, long life and low accident rate, it is well received by users.
