Abstract

During the continuous casting of stainless steel the performance of the mould powder is a key factor in this process. The content of Cr in the steel is up to 18 %, high corrosion resistance of the steel is improved with Al addition, up to 4 %. The aim of the paper was to study the change in physical properties of the casting powder, due to reactions between Al in the steel with SiO₂ in the mould flux during continuous casting. In order to identify the change in the ability of lubrication casting slag with time, depending on the increase in the content of alumina in the slag. On the basis of these results, the most suitable casting powder for continuous casting of ferritic stainless steel with high aluminium content was determined.
