The function of ladle nozzle brick

The ladle nozzle brick usually has a special shape to meet the needs of molten steel flow and pouring. When the molten steel flows out of the ladle, the ladle nozzle brick plays the role of diversion, buffer, and diversion, which plays a vital role in ensuring the smooth flow of molten steel and the quality of steel.
