Abstract
Provided are a heating apparatus configured to generate a coating vapor for coating a base metal (steel sheet) which is continuously transferred in a vacuum state, and a coating device including the heating apparatus. A coating material to be converted into a coating vapor is initially supplied in a solid phase (solid state) and then phase changed into a liquid (liquid state). Thereafter, the liquid-state coating material is supplied to a heating unit, thereby preventing problems such as equipment erosion occurring when a liquid coating material is directly supplied and preventing the decrease of the temperature of a coating material when a solid wire is supplied as a coating material. As a result, the energy efficiency of the heating apparatus may be maximized.
