Investigation of the Tendency for Failure of Refractory Castables in the Wear Lining of a Steel Ladle Using Elongated or Cubic Shaped Tabular Alumina

by

Over the past decades, numerical simulation has proved to be a decisive tool for engineers. In the field of refractory technologies, numerical modelling helps increasing the understanding of the behaviour of refractory linings under service conditions, checking the validity of new designs and potentially predicting the failure of refractory structures.

Numerical Simulation and Experimental Set-up for Predicting the Drying Behavior of Calcium Aluminate Cement (CAC)-Bonded Refractory Castables

by

During the initial heating of Calcium Aluminate Cement (CAC)-bonded castables, physical and chemically-bonded water is released. Therefore, when the refractory’s permeability level is limited, pressure buildup inside the dense microstructure can take place, resulting in cracks and spalling of the ceramic lining.
