The C.I.T.-CIREP Test was designed to simulate the service conditions of refractories when simultaneously exposed to corrosion, mechanical impact and thermal shock. The test procedure is given below.
A special refractory crucible is used (Fig. 1), about its periphery and into which multiple specimens are placed. This allows, within the same environment, to submit individual specimens to one of the following treatment :
- Full immersion into pure molten metal or alloy (no thermal shock & no impact)
- Full immersion & thermal shock
- Full immersion & mechanical impact
- Thermal shock (no immersion)
- Reference specimen
