Abstract
Cast iron, wrought iron, or steel is improved by adding to the molten metal in the ladle or ingot mould a product containing an OH-group, or water of constitution, or both, and an alkaline or alkaline-earth carbonate so as to secure an energetic stirring of the metal by introducing water at the moment of pouring, an atmosphere of carbon dioxide during pouring, and a very fusible alkaline slag to prevent re-oxidation. Boric acid, or an alkaline borate, and a carbonate may be added to the metal in the ladle or ingot mould. Aluminium may also be added to kill the metal.
