Zusammenfassung:The invention relates to a sprayer for micro coating of molten metal. The sprayer comprises a sprayer body and a nozzle part arranged at one end of the sprayer body. The sprayer and a smelting furnace are screwed together through a smelting furnace screwing thread, the molten metal liquid flows out of the inner cavity of the sprayer and small holes of the nozzle part through the smelting furnace, and a metal thin layer is formed on a three-dimensional movement substrate below a molten metal nozzle. A heating device is composed of a resistance wire and a ceramic insulating sleeve, and the heating device is wound on an anti-slip groove of the sprayer. After the sprayer is powered on, the resistance wire of the heating device of the sprayer generates heat, and the problem that the cooling area of the sprayer is larger, and consequently the molten metal in the inner cavity is solidified can be solved. The sprayer is of a split structure; because the diameter of the melt flow-out holes is small, the sprayer is prone to damage; the nozzle part prone to damage can be conveniently replaced due to the split structure, and people do not need to replace the whole nozzle. The sprayer for micro coating of the molten metal is reasonable in structure and low in manufacturing cost, and overcomes the defects that the molten metal is easily solidified, and replacement and repair are not convenient when the sprayer is damaged.
