Formation of oxide inclusions during deoxidation and solidification of high purity steels

摘要

The deoxidation of low alloy steels has been theoretically and experimentally investigated. A calculation method for the description of oxide precipitation in liquid and solidifying steel is presented. Electromotive force sensors were used for continuous control of oxygen activity after aluminium deoxidation in liquid and solidifying steel under laboratory conditions. Examination of the deoxidation products was conducted by means of optical and scanning electron microscopy techniques.
