The phenomenon of loss of mass of metal during its melting
In the course of my melting, in a metallurgical furnace, all the metals gradually go into a vapor state. At this time, and before subsequent solidification at elevated temperatures, all metals, except mercury, and — partially — cesium are in a liquid superheated state. At a time when the temperature of the metal is the same as the boiling point, a secret release of the internal energy of the metal occurs, which is explained by a change in its aggregate state. This is accompanied by a metal burnout — loss of mass during melting. Total losses due to fumes consist of losses due to evaporation of the metal, which increase with increasing temperature, losses due to chemical reactions with alloying additives, slags and atmospheric gases, as well as losses to the formation of oxides that do not dissolve in liquid metal (usually nitrides, intermetallic compounds or some of the refractory carbides).
A very small percentage of fumes is due to the interaction of the melt with the walls of the refractory lining of the furnace (such losses are characteristic only for furnaces that are only put into operation). The magnitude of the burn is determined by the elasticity of the metal vapor, its temperature, pressure inside the working space of the furnace and from the surface area, the transition of the metal to the liquid state.
