Ladle nozzle is a component used in continuous casting to transfer molten metal from a ladle to a tundish. It is typically made of a refractory material, such as high-alumina fireclay, and is designed to withstand the high temperatures and pressures of the casting process. The ladle nozzle is typically located at the bottom of the ladle, and it has a number of small openings, called ports, that allow the molten metal to flow out. The size and shape of the ports, as well as the distance between them, are important factors in determining the flow rate of the molten metal.

Ladle Nozzle Function:

The primary function of a ladle nozzle is to control the flow of molten metal from the ladle into the tundish during continuous casting. It acts as a movable gate that can be opened or closed to regulate the steel flow rate and ensure a steady and controlled casting process. Ladle nozzle is one of the slide gate ceramic elements. Systematic extension of the length of the steelmaking ladle campaign increases the demands on a ladle nozzle. The ideal solution would be a ladle nozzle which withstands the entire ladle campaign. In addition to thermal stability, ladle nozzles must be characterized by high resistance to corrosion and erosion caused by the flow of steel. An important factor affecting the durability of a ladle nozzle is clogging due to steel deoxidation products deposition in the nozzle channel. The phenomenon of clogging makes it difficult to regulate the rate of steel outflow from the ladle and, in extreme cases, can make the nozzle channel close. Clearing the nozzle by oxygen lancing accelerates its destruction.

Ladle Nozzle Advantages:

Buy good quality low cost Ladle Nozzles made of tabular alumina, white fused alumina, sintered spinel, flake graphite, antioxidants and phenolic resin to be produced. They have the advantages of thermal shock resistance stability, good oxidation resistance and corrosion resistance, suitable for all kinds of ladle.
