    Abstract

    An apparatus for measuring thermal conductivity of refractory bricks has been designed using the parallel hot-wire technique and differential platinum thermometry. The equipment has been found to be simpler and less expensive than the thermocomple-based apparatus available commercially. It has shown better reproducibility and proved its applicability for both the low- and high-density refractory types and also for temperatures up to 1250°C.
