Reoxidation in steel

By Petr Kotásek

Abstract

This work is about development and methodology verification of data collection which will be used in the research of the reoxidation in steel castings. To examine reoxidation rate will be measured oxygen activity in the furnace, in the ladle and in the mould. Next it will be evaluated the chemical structure of mould slag, the chemical changes of steel and measured the volume and the area of the casting defects. Each technique is briefly described by the principle of measurement and each method has the results which are analysed. In the conclusion the experiment is summarized and there are mentioned the observations from this experiment

Topics: residual aluminum; secondary slag; oxidation; zbytkový hliník; sekundární struskovitost; reoxidace oceli; oxidace; oxygen activity; aktivita kyslíku; inclusions; vměstky; steel reoxidation
