Abstract
A diffusion component for impregnating molten steel with a gas includes a barrier having a first side and a second side, a through-hole formed within the barrier, the through-hole connecting the first side to the second side, and a porous element arranged within the through-hole such that the flow of molten steel passes over the porous element. At least one flow disrupter is arranged relative to the porous element and configured to promote non-laminar flow of molten steel passing through the through-hole.
Claims20
A diffusion component for exposing molten steel to a gas, comprising:
- a barrier having a first side and a second side;
- a through-hole formed in the barrier, the through-hole connecting the first side to the second side, wherein an outlet of the through-hole is flared to decrease a velocity of molten steel exiting the through-hole relative to a velocity of molten steel entering the through-hole;
- a porous element arranged within the through-hole such that the flow of molten steel passes over the porous element;
- and
- at least one flow disrupter arranged in the through-hole and configured to create non-laminar flow of molten steel passing through the through-hole.
