EVAPORATOR FOR METALS Russian patent published in 2009 - IPC C23C14/26 B22F9/12 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy, particularly to evaporators for metals and can be implemented for fabrication of metal powders and for applying coating on various surfaces. The evaporator consists of a resistive heater, a circular evaporating chamber with a steam pipeline and with circular capacities for metal melt having overflow ports, the circular capacities are located in the circular evaporating chamber, then the evaporator consists of a sprayer unit located in the steam pipeline of the evaporating chamber and of a channel for supplying melt into the evaporating chamber. Also the heater is made as a heating rod. The evaporator is equipped with a tube element placed on the outside of the heating rod and coaxial to it and with a curricular metal receiver-melter disposed coaxially to the tube element on its upper part. The circular evaporating chamber is arranged in the heating rod, while the steam pipeline is made in form of an axial channel in the upper part of the heating rod and in form of tangential channels conjugated with it and with upper part of the evaporating chamber. The tube element is connected with the heating rod in the zone of the spraying unit assembly, while the channel for melt supply is coupled with the circular metal receiver-melter and with the upper circular capacity of the evaporating chamber.

EFFECT: reduced losses of electric power, and preventing steam condensation in sprayer unit and its obstruction with condensate products.
