摘要：

Experiments on plasma heating of a burnt periclase-carbon refractory are performed. The heating rate is high, more than 1000 K/h. The thermophysical properties of the burnt refractory are refined using the experimental results. The burnt periclase-carbon refractory has a lower thermal conductivity than the green refractory (9.5 and 25 W/(m K), respectively) and a higher emissivity factor (0.6 and 0.3, respectively). The experimental data are used to refine the parameters of the CFD model of plasma heating of the periclase-carbon refractory, which will allow one to simulate the process of heating more exactly.
