Oxygen blowing-oxygen lance & lance tips

high-efficient oxygen blast demand and shorten the time of blowing, then you will get steelmaking efficient.

ANSSEN advantages:

Associating with the central Iron and Steel Research Institute, we can optimize the Lance nozzle by your steelmaking practice. This would be suitable for your high-efficient oxygen blast demand and shorten the time of blowing, then you will get a better steelmaking efficient.The nozzle produced by the technology of vacuum casting has high-density organization with high copper purity, good thermal conductivity and long service life.                                                  With reliable welding technology of copper, and steel, the products, adapt to high temperature and high strength working conditions.The life of the nozzle used at the 250t BOF of the second plant of Baosteel increases by 30% than that the ordinary nozzle.The assembled nozzle made by forging has the properties of closely grain, high-density organization , high temperature resistance and strong resisting fatigue.BY optimal designing the nozzle's inside passage of cooling water, the passage has smaller water resistance and good cooling effect.
