After converter tapping, this facility add coating materials, such as magnesia,
dolomite, to slag in converter and uniformly attach them to refractory bricks by
blowing high pressure N2 gas through lance.
This facility allows stable maintenance of converter and long life time of refractory
N2 Splash Slag Coating of No.2 bricks. As a result, it is expected to reduce expenses.
