Abstract

PURPOSE:To prevent splash generation of molten steel, by applying sticking material, generating gas with decomposition by the heat of molten steel, on the outer surface of cannonball shape billet, at the time of shotting small cannonball shape billet, composed of deoxidant or alloy element, such as Al, Mg, Ca etc., having small specific gravity, deeply into molten steel.
