Abstract
High-temperature treatment of melts (HTTM) is used in metallurgy and casting as the most important technological operation for the production of highalloy steels and alloys. HTTM is accompanied by the overheating of a melt to the deactivation temperature of various impurity particles (substrates) contained in an alloy and by holding the overheated liquid metal under these conditions for its homogenization [1]. Thermodynamically, the introduction of thermal energy into a melt can be considered as an external action on a liquid metal. Melt heating is accompanied by a deviation of its temperature from the equilibrium melting temperature and by the appearance of various flows and related thermodynamic forces in the melt. Thus, HTTM should be analyzed using the laws of nonequilibrium thermodynamics [2].
