Crystallization of Aluminum Oxide in Liquid Steels
摘要
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.
