Tundish Nozzle Block for Continuous Casting Manufacturers
A tundish nozzle, also known as a tundish slide gate nozzle, is a crucial component in the continuous casting process of molten metals, particularly in steel production. It is located at the bottom of the tundish, which is an intermediary vessel that holds the molten metal before it’s fed into the molds to create solidified steel products.
The tundish nozzle serves as a controllable valve that regulates the flow of molten metal from the tundish to the molds below. It’s designed to minimize turbulence and improve the distribution of the molten metal, ensuring a consistent and controlled stream into the molds.
The process begins with selecting a suitable refractory material that can withstand the extreme temperatures and corrosive nature of molten metal. Common materials include zirconia, alumina, magnesia, and graphite, each offering specific properties to meet the requirements.
The chosen refractory material is mixed with binders and additives to create a workable paste or slurry. This mixture is then molded into the desired shape of the tundish nozzle using techniques like slip casting, extrusion, or press forming. The molds used are often made from materials that can withstand the pressures and temperatures during molding.
The molded tundish nozzle is carefully dried to remove excess moisture and binders. This is a critical step to prevent cracking and ensure proper firing in the subsequent stages.
