Overview of refractory slide nozzle
The refractory slide nozzle is a device used to control and regulate the flow of molten steel. After the molten steel leaves the electric furnace and enters the continuous caster through the nozzle, the refractory slide nozzle will control and regulate the flow of molten steel to ensure smooth flow and accurate positioning of the molten steel.
Raw materials for refractory skateboard nozzle
1. High-aluminum refractory mud material: High-aluminum refractory mud material is a commonly used refractory raw material. It has excellent high temperature resistance and excellent wear resistance. It can be used to build and repair refractory slide nozzles.
2. Graphite material: Graphite material has high temperature resistance and corrosion resistance, and is often used to make guide plates for refractory skateboard nozzles.
3. Lightweight high-temperature insulation materials: Lightweight high-temperature insulation materials are lightweight, heat-insulating, have good pressure resistance and excellent corrosion resistance. They are often used to make the insulation layer of refractory skateboard nozzles.
4. High aluminum oxide material: High aluminum oxide material has good high temperature resistance and corrosion resistance, and is often used in the manufacture of bricks and masonry for refractory slide nozzles.
Manufacturing of refractory slide nozzle
The manufacture of refractory slide nozzles requires the selection of the above-mentioned raw materials, and processes such as mixing, molding, drying, and sintering to form a complete refractory slide nozzle. The manufacturing process strictly requires each step to comply with standards to ensure that the manufactured refractory slide nozzle has good fire resistance and service life.
