New types of unfavorable nonmetallic inclusions based on MgO–Al2O3 and metallurgical factors governing their content in metal. Part 2. Transformation mechanisms for nonmetallic inclusions based on alumina magnesia spinel. Main approaches making it possible to reduce the content of the inclusions in question in steel

The main mechanisms are considered for formation and transformation of non-metallic inclusions based on alumina magnesia spinel, and the unfavorable effect on corrosion resistance of carbon and low-alloy steels in aqueous chlorine-containing media. Basic approaches are demonstrated making it possible to reduce the content of the inclusions in question in steel aimed both at reducing the content of inclusions during steel smelting, and on limiting the possibility of their transformation during steel continuous casting and hot rolling.
