High Alumina Castables / Plastics are generally used as an original refractory lining and also used as a topup material to repair the wornout lining. The ladle lining can be broadly classified as follows:

• Brick Lined
• Fully Monolithic Lined ladles are preferred over the brick lining due to following benefits;
– Longer Life / Lower Downtime
– Jointless lining minimising metal / slag penetration
– Lesser Wear pattern
– Lower Shell temperature / Energy Saving
– Zero Refractory Inclusion
– Labour Cost Reduction

For smaller ladles precast prefired shapes are preferred. The extended heats are achieved by usage of appropriate patching castables.
