Abstract
Abstract A continuously cast body emerges from its mold in a hot, solid and relatively scale-free condition and passes immediately into a chamber prior to any substantial formation of scales on the body. In this chamber a powder of metals and metallic oxides which fuse at the temperature of the body are blown against it and melt. On cooling this melt hardens to form a thin glassy, enamellike coating which ruptures in the region of any surface flaws to indicate the presence of the latter and which protects the body from further scaling as it fully cools.
