Situation
• Formation of scale during the production and processing of steel
• Loss of material
• Adverse effect on surface quality
• Inadequate descaling in washbox descalers
• Heightened maintenance requirement

Solution
• Analysis of the scale formation mechanisms
• Laboratory and field experiments
• Prediction of scale formation with BFI scale model
• Optimisation of temperature control
• Optimisation of furnace atmosphere

Benefits
• Improvement of process control
• Reduction of material losses
• Decrease of recoverable materials cycles
• Better descaling in washbox descalers
• Improved surface quality
• Minimisation of subsequent corrective measures
