摘要： The present invention discloses a vacuum coating device, comprising: a crucible; an induction heater provided on the periphery of the crucible; a flow distribution box connected to the top of said crucible via a steam pipe. Wherein said flow distribution box is provided inside with a horizontal pressure stabilizing plate, said flow distribution box is connected on the top with a nozzle, said steam pipe is provided with a pressure regulating valve, and said pressure stabilizing plate has a multi-hole structure. The lower surface of said pressure stabilizing plate is connected to a horizontal flow suppression plate, and a space is formed between the side of said flow suppression plate and the inner wall of said flow distribution box. A jet moderating zone is formed between the joint where said flow distribution box and said steam pipe are connected and the lower surface of said pressure stabilizing plate, and a jet accelerating zone is formed between the upper surface of said pressure stabilizing plate and the joint where said flow distribution box and said nozzle are connected. When the high-temperature steam reaches the low-temperature steel plate, a uniform coating can be formed on the steel plate surface.

摘要： Disclosed in the present invention is a vacuum coating device for uniformly distributing metal steam by using a guide plate type structure. The vacuum coating device comprises a crucible, wherein an induction heater for heating molten metal in the crucible to form metal steam is arranged outside of the crucible. A top of the crucible is connected to a flow distribution tank body by means of a metal steam pipeline. A horizontal core rod and a pressure stabilizing plate are arranged inside the flow distribution tank body. The core rod is located below the pressure stabilizing plate. A coating nozzle is arranged at the top of the flow distribution tank body. An induction coil is arranged on the outer side of the flow distribution tank body. A pressure regulating valve is arranged on the metal steam pipeline. A plurality of axial heating holes are provided inside the core rod, resistance wires are arranged inside the heating holes, and a primary guide plate, a secondary guide plate and a tertiary guide plate are arranged on the surface of the core rod; and a buffer groove is provided on the inner wall of the flow distribution tank body, and the buffer groove corresponds to the core rod in position. According to the present invention, when high-temperature steam makes contact with a low-temperature steel plate, a uniform coating is formed on the surface of the steel plate.
