It is important to maintain a consistent iron/slag inventory inside a blast furnace for stable operation, especially to avoid iron/slag level beyond certain limit that may lead to serious hearth chill situations.

Solution

An engineering solutions partner developed a casting guidance model for iron and steels plants. It uses real-time blast furnace information to advise on taphole and other parameters that estimate current iron/slag level. It predicts trends based on future furnace operation and cast schedules.

Benefits

Stabilize furnace operation and hot metal supply downstream. Better management of the furnace pressure drop by maintaining a consistent dry hearth condition. Essential for reaching the maximum furnace output.
