Refractory testing methods
WebRefractory materials are classified into three types based on fusion temperature (melting point). Normal refractories have a fusion temperature of 1580–1780 °C (e.g. Fire clay) High refractories have a fusion temperature of 1780–2000 °C (e.g. Chromite) Super refractories have a fusion temperature of > 2000 °C (e.g. Zirconia) WebRefractoriness under load is a measure of the behaviour of a refractory material subjected to the combined effects of load, rising temperature and time. Principle A cylindrical test …
