FURNACES AND REFRACTORIESModern Eq
Lightweight refractories of low thermal conductivity find wider applications in low temperature heat treatment furnaces for example in batch type furnaces where the low heat capacity of the refractory structure minimizes the heat stored during the intermittent heating and cooling cycles. Insulating refractories have very low thermal conductivity.
