Cleaning method for surface of sheet steel

A cleaning method for a surface of sheet steel in which a jet of liquid ejected from a nozzle collides with the surface of the sheet steel containing over 0.5wt% of Si to clean the surface of the sheet steel. The temperature of the sheet is over 850 DEG C and droplets, produced in a droplet flow are...

Beschreibung
Zusammenfassung:	A cleaning method for a surface of sheet steel in which a jet of liquid ejected from a nozzle collides with the surface of the sheet steel containing over 0.5wt% of Si to clean the surface of the sheet steel. The temperature of the sheet is over 850 DEG C and droplets, produced in a droplet flow area of the liquid jet from said nozzle collide with the surface of the sheet steel in the following condition thereby cleaning the surface of the sheet steel:- where P denotes an ejection pressure, and W denotes an amount of liquid to be ejected.
