Fan nozzles have a wide range of applications in the steel industry. Electric furnace dust removal, coke flameout, slab continuous casting, roll cooling, strip lubrication, cooling cleaning, power plant desulfurization and steel removal of phosphorus. Among them, the dephosphorization of rolling steel is to ensure the quality of the surface of the steel, thereby removing the iron oxide scale on the surface of the steel billet and the regenerated iron oxide scale during the rolling process. The mechanical method of removing the iron oxide scale from the previous phosphorus-breaking machine and crushing the scale of the iron oxide is transformed into a high-pressure water sprayed by the nozzle to remove the scale by high-pressure water.

The working principle of fan nozzle in steel removal of phosphorus:
Under the action of the fan nozzle, the high pressure water forms a large surface. Under the action of this high-pressure fan-shaped water jet, the scale is subjected to a process of being cut, quenched, peeled off from the base metal, and washed away from the surface of the billet (or intermediate billet) to remove the scale.

Effective steel removal and phosphorus removal has the following advantages:
1. High quality products. Improve the surface quality of the rolled stock.
2. High production efficiency. Reduce roll consumption, thereby increasing production efficiency.
3. Low cost of use. Can improve pickling efficiency and reduce acid consumption.
4. Reduce energy consumption. Use nozzles to save water and save energy.
