Název v původním jazyce
State of the art of metal reoxidation study of iron castings
Popis výsledku v původním jazyce
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
