Innovations in Lining of Aluminium Processing Furnaces

by

Close and fruitful cooperation between this two companies lasts for nearly 25 years. DITHERM a.s. Praha, engaged in engineering, innovative designs and installations of refractory linings of thermal aggregates, and Průmyslová keramika Rájec-Jestřebí, a producer of predominantly non-shaped refractory masses and prefabricates made from these masses.

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.
