Feed Nozzle Ears Use in Aluminum Plate Casting and Rolling Process

The structure of the feed nozzle is diverse, which can be selected according to the respective process and equipment conditions. The open size of the gasket can change with the change of the plate width. During processing, try not to have sharp corners and dead corners in each runner and block.

When assembling the gasket on the mouth fan, it is necessary to ensure that the flow path is unobstructed and the temperature is evenly distributed. When assembling, the gasket can be fixed on the mouth fan with a pin. The processed flow nozzle should be placed in a holding furnace for heat preservation before use, and the holding temperature is about 150℃.

The aluminum silicate castertip ear is the side work piece of the mouth, its function is to block the molten metal from flowing from both sides. Each pair of mouths needs two side ears.

The side ears are made of aluminum silicate red adhesive by bonding and pressing. They are often used as side ears on inclined casting and rolling mills. Before use, the ear tips are soaked in graphite aqueous solution for 3-5 minutes and then dried. The side ears are composed of three parts, namely aluminum plate, heat-insulating plate and graphite ear tips. They are often used in horizontal casting and rolling mills as side ears.

The castertip 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.
