During use, argon gas is blown into the ladle through the purging 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, with high blowing rate, safe 

and reliable operation, long service life.

Application: core components for refining and post-furnace treatment

Main physical and chemical performance index:

Note: TN-TQZ is purging plug, TN-GBZ is ladle nozzle well block, TN-SF is corundum self-flowing castable
