  Melt oxidation by atmospheric oxygen from the melting start up to the end of metal solidification and cooling in the foundry mould is an accessory effect at manufacture of castings from ferrous alloys. Reoxidation processes have considerable influence on oxidic purity of cast ferrous alloys and material and technological properties related to it. They are also a cause of great numbers of serious metallurgical defects, often irreparable ones. The book deals with problems of reoxidation processes of ferrous alloys, i.e. both steels and cast irons. Not only the course and conditions of those processes are studied here but their consequences too, in particular the metallurgical defects resulting from the substance of reoxidation processes.

  Cast iron are the basic structural material and they form 75% of the world production of castings. The crystallization of cast iron and the formation of graphite are a complex process influencing by oxygen.

  Metal reoxidation causes a number of iron castings defects, particularly when pouring them in green-sand moulds. One of them is pinholes the occurrence of which is explained by several hypotheses. One of possible causes is reoxidation processes in the foundry mould cavity. During its flowing in the gating system and in the mould cavity the liquid metal gets into contact with oxygen from air and water vapour. Secondary oxidation of elements takes place in sequence of their affinity to oxygen. Therefore the authors were aimed at cast irons. Besides indirect methods the reoxidation was researched mainly by direct measurement of oxygen activity during filling of a mould up to solidus temperature. Continuous monitoring of oxygen activity changes in a foundry mould is an original solution since other authors have done their measurements only in a furnace with disposable sensors. Obtained results have confirmed that oxygen activity measurement can serve to the casting quality control. But it is little sensitive for explanation of processes running in a cavity during metal casting.

  Recent advances in understading the processes of casting metals into green sand moulds have shown that the occurrence of reoxidation plays a key role in the control of the quality of casting.
