Characteristics:

■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.
