Original abstract
Recent advances in understanding the metal-casting processes into green sand moulds have indicated that reoxidation plays a key role in the quality control of castings. As the liquid metal enters the mould cavity, thermal degradation of binders, water, and additives produces large quantities of gases and vapours. Air oxygen, mould atmosphere or oxides in the moulding sand can reoxidize the metal flow. Imperfect filling of castings induces agitation of the metal flow with oxygen present in gases and vapours, which results in secondary oxidation or the so-called metal reoxidation. Reoxidation processes in liquid metal can cause a number of defects in iron and steel castings.
