Cleaning method for surface of sheet steel

摘要

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:- $where\; P\; denotes\; an\; ejection\; pressure,\; and\; W\; denotes\; an\; amount\; of\; liquid\; to\; be\; ejected.\mathop{\mathrm{image}}$
