The fracture of refractory anchorage components is a recurring theme when furnace systems are repaired and replaced. It is often difficult for furnace operators to understand why the components final. There are many considerations to take into account, such as: Insufficient expansion/contraction allowance; Local anchorage failures inducing excessive stress; Poor material selection; Presence of high temperature metallurgical phases that are brittle at lower temperatures. causing failure during thermal cycling; Anchorage component designs that introduce stress concentrations, and many other factors, listed in this paper, the purpose of which is to consolidate the ideas associated with the above material items into a useful design tool that is accessible to all designers and operators of refractory lined furnace systems.
