Plasma Heating of Periclase–Carbon Refractory

Abstract

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.
