Abstract
Dissolved hydrogen acts as a demodifying element in the formation of aluminum oxide microcrystals in liquid steels. Hydrogen atoms in liquid steels serve as surface-active elements for aluminum oxide microcrystals. Modifiers significantly reduce the hydrogen concentration in steel melts. This enhances the process of coagulation of aluminum oxide microcrystals into large particles that quickly float in liquid steels. To more effectively remove aluminum oxide particles from them, the casting process should not begin immediately after treating steel melts with modifiers.
期刊介绍：
Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
