DEVELOPMENT OF NEW CERAMIC COMPONENTS WITH BETER LIFETIME,TO CONTROL MELTED METALS CASTING

Objective

This project aims at developing new ceramic components with better lifetime, better macro-cracks resistance and no tap air?pollution.

This new design, based on thermal considerations, leads to the exclusive use of axial symmetrical ceramic components resulting in largely improved thermal shocks resistance.

This new design, based on thermal considerations, leads to the exclusive use of axial symmetrical ceramic components resulting in largely improved thermal shocks resistance.

Operated works, through exploring thermophysical properties, has led to determination of temperature and thermal stress distribution.
By computer simulation it has been possible to find out that for all materials, cracks will appear within a few seconds.
These simulations also showed that a ceramic plate will remain crack free if a compressive load, provided by a steel bandage, is applied.
In the thermomechanical field the new axisymmetrical concept plate has already proved highly valuable.
