Refractory Porous Plug Breathable Brick for Ladle Bottom

Refractory Porous Plug Breathable Brick for Ladle Bottom are manufactured with high-purity white corundum, tabular alumina and fused magnesia as aggregates.

As the core functional component for ladle bottom argon blowing refining, they are installed at the bottom of ladles.

By injecting argon into molten steel to achieve intense stirring, these bricks serve as a key refractory material for producing clean steel and improving molten steel quality.

Argon gas is blown into molten steel to create vigorous stirring, which eliminates temperature gradients and enables rapid and uniform distribution of chemical compositions, alloys and deoxidizers to

Ladle breathable bricks are installed at the bottom of the ladle.

Air bubbles absorb inclusions and carry them upward, removing harmful gases and improving steel cleanliness.

They also accelerate reactions at the slag-steel interface and greatly boost desulfurization and deoxidization efficiency.

Meanwhile, the bricks stabilize the continuous casting temperature and flow field, thus enhancing the quality of cast billets.
