The feed nozzle, also known as the casting tips and nozzle, is a key component that directly distributes and transports the liquid metal to the roll gap during the continuous casting and rolling process. The feed nozzle is composed of a mouth fan, gasket, and edge ears. Commonly used materials for the feed nozzle are MARINITE, STYRITE, etc.
The casting tips and nozzle is a key part of continuous casting and rolling production. Its forms are not the same, but they are all equipped with oval angular or other shaped baffles at the entrance of the liquid metal, so that the liquid metal flows into both sides. The basic principle is to use The liquid metal flows out of the mouth evenly to ensure the consistency of the metal temperature and flow rate.
The feed nozzle is a refractory board made of ceramic fiber and silicon aluminum fiber through vacuum pressing. It is a lightweight refractory product. Its characteristics are: at high temperatures, good stability and small expansion coefficient; good heat preservation, The thermal conductivity is small. It has good thermal shock resistance; does not react with molten metal and is resistant to metal corrosion; it has good processing performance and can be processed at will.
