Title: Oxygen blowing lance
Inventor: FUKUMI JUNICHI
IPC: C21C5/46
Filed: 1986-03-18
Abstract: PURPOSE:To provide an oxygen blowing lance which can improve secondary combustion efficiency by providing ejection ports for gaseous O2 for secondary combustion around the blowing reaction region where the blowing reaction is generated by the gaseous O2 ejected from ejection ports of gaseous O2 for blowing. CONSTITUTION:The gaseous O2 for blowing is blown from the ejection ports 16 of gaseous O2 for blowing via a gaseous O2 flow pipe 12 and a gaseous O2 ejection pipe 13 toward a molten steel 20. The molten steel 20 is thereby splashed circumferentially like granular drops and CO is generated in said part by the blowing reaction. On the other hand, the gaseous O2 for secondary combustion is ejected downward from the ejection ports 17 of gaseous O2 for secondary combustion via a gaseous O2 flow pipe 15. The ejection ports 17 exist right above the ejection ports 16 in this case and therefore, the greater part of the gaseous O2 for secondary combustion is blown to the circumference of the ejection area of the gaseous O2 for blowing, i.e., the circumference of the blowing reaction region. The probability of the contact of the gaseous O2 for secondary combustion with CO is consequently extremely high. The gaseous O2 for secondary combustion, therefore, contributes effectively to the secondary combustion so that the secondary combustion is efficiently executed even if the oxygen feed ratio of the secondary combustion is increased.
