The argon gas is blown into the steel ladle through the porous plug, and the molten steel is strongly stirred. The main function and purpose are: uniform molten steel composition and temperature, and promote the collision floating of inclusions.
Features: good thermal stability, scour resistance, erosion resistance and permeability resistance, high blowing rate, safe and reliable operation and long service life.
Application: core components for refining and post-furnace treatment
