XL-TQ series ladle bottom argon-blowing breathable bricks are made of high-purity, high-density, and high-strength materials. They are made of chromium corundum, corundum spinel and radial straight-through slit-type breathable bricks. They have stable structure, maximum ventilation and easy air flow. The characteristics of adjustment, high blowing rate, erosion resistance, erosion resistance and long life are good for purifying molten steel and uniform composition and temperature. Mainly applicable to the bottom of ladle.
