“…Methods to protect the teeming stream in ingot casting practice can be classified into the following types: (1) shrouding by an inert gas curtain injected through a steel ring manifold or porous refractory ring around the teeming nozzle, [168,169] (2) using an intermediate shroud box seated on top of the trumpet with injection of inert gas either directly or through a porous refractory ring, (3) purging inert gas into the runner system and mold before teeming, [168,170] and (4) carrying out teeming in vacuum. [171] Argon is a much better inert gas to prevent reoxidation than carbon dioxide [170] or nitrogen, which are subject to other detrimental reactions. [167,170] Schlatter reviewed teeming stream protection systems for ingot casting, and evaluated sealing methods between teeming nozzle and trumpet, mold purging, and flooding the slide gate box with inert gas.…”

This article extensively reviews published research on inclusions in ingot steel and defects on ingot products, methods to measure and detect inclusions in steel, the causes of exogenous inclusions, and the transport and entrapment of inclusions during fluid flow, segregation, and solidification of steel cast in ingot molds. Exogenous inclusions in ingots originate mainly from reoxidation of the molten steel, slag entrapment, and lining erosion, which are detailed in this article. The measures to prevent the formation of exogenous inclusions and improve their removal are provided, which are very useful for the clean steel production of ingot industries.
