Study of the thermal-shock resistance of ultralightweight refractories

A complex investigation was carried out into the thermal shock resistance of ultralightweight refractories ShUB-0.4, ShLB-0.6, and ShLBDS-0.4. Using calculations and experimental techniques and specimens in the form of plates and standard bricks we established the criterion values for thermal shock resistance. It was shown that the refractory ShLBDS-0.4 is the most thermally shock resistant product of those investigated.
