OptDeslag – Improved deslagging and slag conditioning

Initial situation:

• Performance of many metallurgical operations is significantly influenced by the condition of the slag
• Therefore in some cases the slag has to be removed as far as possible
• When the deslagging process is overdone, liquid steel from the liquid bulk may also be removed, which contributes significantly to losses of steel

Working topics:

• Monitoring of deslagging operations using CCD and IR cameras
• Development of dynamic online process models
• Sampling and analysis for verification

Results:

• Reproducible performance of the deslagging process
• Online determination of the amount of remaining slag
• Minimise amount of remaining slag before entering secondary metallurgy
• Predict impact of remaining slag on metallurgical operations
• Calculate set-points for slag conditioning
