Abstract
Plasma-arc heating of periclase-carbonaceous refractory was experimentally tested. A high heating rate of 600°C/h was achieved. The experimental results were used to correct the thermal characteristics of raw refractory and to determine the energy characteristics of the arc discharge. Raw periclase-carbonaceous refractory has high heat conductivity (25 W/(m·K)) and low emissivity (0.3). The radiated power (130 kW) of the discharge is calculated from spectral measurements of an argon plasma arc with a current of 1000 A and an arc voltage of 150 V. The obtained data are used to specify the parameters of the CFD-model of plasma-arc heating of periclase-carbonaceous refractory.
