Analyse refractory failures
Assessment tool
Version 1.0
Issue Date: June 2024
Refractories may fail due to a number of reasons, and these may be mechanical (wear, impact) or thermal (thermal stresses, flame impingement) or due to other reasons. The analysis of failures is important so that replacement refractories can be better designed to reduce this failure and extend the time between failure/ replacement.
This unit covers all common types of refractory failures. The failure needs to be recognised and distinguished from other possible causes. Possible causes for the failure also need to be identified particularly if failure is unexpected/refractory life is shorter than expected
This unit would typically be undertaken by a technician working either alone or in liaison with another refractory expert.
This unit of competency covers analysing a refractory failure to determine failure mode. It involves understanding failure modes, differentiating different modes and understanding forensic procedures.
