Abstract
Provided is a vacuum coating device, comprising a crucible (), an induction heater () arranged on the outer side of the crucible (); a flow distribution box connected to the top of the crucible () through a steam pipeline (); a pressure regulating valve () and a diverter valve () sequentially arranged in a direction in which the steam pipeline () is in communication with the flow distribution box; a horizontal pressure stabilizing plate () arranged in the flow distribution box, a plurality of sub-nozzles () connected to the top of the flow distribution box; wherein a plurality of air flow distribution chambers are arranged in the diverter valve (); a ratio of a total area of the air flow distribution chambers (S) to an area of the steam pipeline () in the radial direction (S) is greater than or equal to 0.1, i.e.: S/S≥0.1. According to the device, a uniform spray flow can be formed, a uniform coating () is formed on the surface of a steel plate () when high temperature steam is in contact with a low temperature steel plate, the spray flow formed by the sub-nozzles () arranged at the rear portion continuously covers the deposited metal layer that has been formed, so as to achieve efficient coating of strip steel under vacuum conditions.
