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.
