DESCRIPTION
A tundish lower nozzle is an important component in the process of alloy casting. It is used to regulate the flow of molten metal as it passes from the tundish into the ingot mold. The nozzle is typically made from refractory material, which can withstand high temperatures and resist erosion from the flowing metal.
The design of the lower nozzle is critical to ensure that the molten metal can flow smoothly and evenly into the mold. It must also be able to withstand the high pressures and temperatures of the casting process without cracking or breaking.
There are several types of tundish lower nozzles available, including ceramic, ceramic fiber, and steel. Each type has its advantages and disadvantages, depending on the specific requirements of the casting process.
Some of the key factors to consider when selecting a tundish lower nozzle include the type of alloy being cast, the size and shape of the ingot mold, and the casting temperature and pressure. Proper selection and installation of the nozzle can help to optimize the casting process and improve the overall quality of the final product.
