Process and device for melting glass
First Claim
1. A device for melting glass before pouring onto a float bath, comprising a melting furnace for the tank having means defining zones which are a melting zone, a refining zone, and a homogenization zone separated from the refining zone by an intermediate zone, and means for agitation of the molten glass in the tank, wherein the means for agitation are located in the intermediate zone and are comprised of (1) at least one horizontally extending agitator formed of a series of essentially vertically downward extending loops and horizontally extending means horizontally connecting said loops, with said loops extending over essentially the entire width of the tank, and are further comprised of (2) means imparting to each point of the agitator an elliptical motion in a horizontal plane the imparting means being capable of varying the axes of the ellipse traversed by said each point of the agitator.
