Description
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
