Yintoni ulwahlulo izitena zokufakelwa kwe-thermal ezilula

Izitena ezikhanyelayo zokugquma. Kubhekiselwa kwii-refractories ezine-porosity ephezulu, ubuninzi obuphantsi, kunye nokuhanjiswa kwe-thermal ephantsi. Iquka i-aluminiyam ephezulu yokukhusela ubushushu obukhuselayo obulula, izitena ezinqabileyo ezisekelwe kudongwe ezisekelwe kwi-heat-insulating lightweight refractory, i-diatomite i-heat-insulating lightweight refractory izitena kunye namaso adadayo Ezi ndidi ezine zezitena.
