Abstract
A method of agitating a bath of melted metal for treating the same by blowing gas into a columnar body of such melted metal disposed in the bath to cause the apparent specific gravity of the columnar body to be reduced and to thereby be hydrostatically lifted, and returning the lifted portion of the melted metal to the bath by pouring the same with a splashing effect onto the free surface of the bath, in a manner to continuously change the pouring position on the free surface of the bath, thereby causing improved agitation of the bath, and especially improved contact and mixing of the melted metal and a treating agent generally floating on the free surface of the bath.
