Based on the fact that the blast furnace slag tapping flow will exceed the granulator capacity, the slag flow is limited to a specific flow level applying refractory slag divider. Just before the slag entrance into the granulator the slag can be diverted to a slag emergency pit in case of an emergency shut down of the granulator.

Slag Granulation with Continuous Dewatering Ironmaking

The slag granulation area links the hot slag runner of the blast furnace and the INBA dewatering system. This link is directly accomplished through the use of a granulation tank. The granulation tank creates a compact layout, which allows a reduced water circuit design with op- timal heat transfer conditions in addition to better product quality.
