During use of purging plug, 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.
PRODUCT ADVANTAGES
Good thermal stability
Scour resistance
Erosion resistance and permeability resistance
High blowing rate
Safe and reliable operation and long service life
