Description

Ladle argon blowing nozzle

Technical Field

The utility model relates to the technical field of ladle argon blowing, in particular to a ladle argon blowing nozzle.

Background

Argon is blown into the molten steel from the bottom of the steel ladle through the air brick arranged at a certain position at the bottom of the steel ladle. The argon forms a large number of small bubbles, which are equivalent to countless small vacuum chambers for harmful gas H, N and deoxidation product CO in molten steel, and can gradually take away the gases, the principle is the same as that of vacuum degassing, and the argon is superior from the aspect of kinetic conditions. Molten steel is stirred when the argon bubbles float upwards, so that the opportunity of gas phase nucleation and collision and aggregation of inclusion particles is provided, and the elimination of gas and inclusions is facilitated.
