Objectives:• Reduce labour time and costs• Improve safety and work conditions• Reduce pre-heating time• Improved insulation and

temperature control

Alloy:ferritic ductile iron 450/10

Ladle size:Tundish cover ladle processUseful capacity 2.3 tonnesTreatment temperature 1480 °CFurnace tapping temperature 1520 °C

Ladle installation:• Total weight of KALTEK ISO 60BF =

850 kg• Thickness: from 85 mm to max

120 mm• Installation time: 2 hours• Reaction time: 1 hour• Pre heat: for 1 hour maximum

Lifetime of the ladle:1150 tons treated500 cycles of FeSiMg treatment1 day continuous operating followed bycleaning

Earlier lining practice:Ramming granular silica/graphite refractoryTotal weight of lining = 1275 kgInstallation time 4 hoursDry-out 9 hoursPre heating 4 hours750 tons treated

Improvements:Installation and ladle cost reduced by 10%:• Installation time halved• Drying time reduced by 8 hours• Pre-heating time reduced by 3

hours• 35% reduction in lining weight• 35% increase in lining lifetime

Cost reduction due to improved insulating properties:• 20°C reduction in furnace tapping
