Abstract

A covering powder, for use in metal casting, consists of two superposed layers, the lower layer being of slag-forming material which melts at low temp and the upper layer being of refractory, heat insulating material. The lower layer pref. contains additives which promote self-fluxing and comprises a mixt of oxidising powder (esp. alkali metal nitrate or iron oxide) and reducing powder (esp a deoxidant such as Al or Si). Used esp in the casting of steel ingots.
