Abstract

The high quality of steels depends to a great extent on gaseous inclusions, their amount and dispersion being influenced by two possible methods of degassing smelts: vacuumizing and bubbling with inert gas. Taking into account this topic, the paper emphasizes experiments concerning: The explanation of scientific dilemmas on kinetics of hydrogen removal; Establishing optimal values for the hydrogen and nitrogen removal rate; Role of bubbling smelts with argon..
