The C.A.T.-CIREP Test was designed to simulate the service conditions of refractories when simultaneously exposed to corrosion, abrasion and thermal shock. The test procedure is given below.
A special set-up is used (Fig. 1). Its advantages as compared to conventional abrasion test set-ups are the following:
- It allows refractory abrasion testing at room and high temperature;
- Test conditions can be adjusted to wear refractory samples only on central region of an exposed face, but leaving enough sample to measure residual mechanical properties such as rupture force;
- The set-up can ben used to study the effect of separate and combined action of abrasion, erosion, corrosion and thermal shock;
- An exposed face can be submitted to combined action of abrasion and/or erosion and corrosion, while the two adjacent faces (Fig. 2) are exposed only to erosion and corrosion effect. The opposite face would be subjected only to corrosion wear. The contribution of abrasion on the kinetics of corrosion can therefore be determined;
- Dynamic or static corrosion of a refractory material partially or totally immersed in molten metal can be applied to study the influence of oxygen partial pressure on corrosion kinetics;
- No vortex generation as the samples act as a baffle.
