The paper considers the possibility of energy saving high-temperature processes for producing melt. Reducing energy consumption is ensured by a set of measures aimed at intensifying the process of degassing of the melt and increasing its efficiency. Presented are modern methods of degassing melts. The main parameters that determine the nature of the movement of gas bubbles in the melt are the Reynolds criterion and the dynamic viscosity of the melt. The viscosity of the basalt melt decreases with increasing temperature. The creation of vacuum conditions in the degassing chamber provides a multiple increase in the rate of degassing of the melt and a decrease in heat loss to the environment.
