Document Type and Number:
Japanese Patent JPS5422402
Kind Code:
B1
Abstract:
Slag recovered from a previous electroslag remelting of a metal or similar thereto is dried and ground into a fine powder and then mixed with a metal to be added to an electroslag melt, e.g., of steel, in order to alloy it or deoxidize it. The mixture is formed into granules having a density closer to that of the slag than to that of the metallic component from which the granules were formed. These granules can even be lighter than the slag in the melt, so that when added they float thereon. Thus, when the granules are charged onto the melt they spend a relatively long time in contact with the relatively hot slag so that their nonmetallic component is absorbed into the slag while their metallic component is slowly released and thereby afforded sufficient time to heat up and react with the slag or to melt completely before passing into the body of molten metal udner the slag.
