METHOD FOR MANUFACTURING HOT-DIPPED ALUMINUM PLATING STEEL PLATE OF WHICH SURFACE APPEARANCE OF THE STEEL PLATE IS IMPROVED, CAPABLE OF RESTRICTING SPANGLE PRODUCTION ON HOT-DIPPED COATING SURFACE

摘要

PURPOSE: A method for manufacturing hot-dipped aluminum plating steel plate of which surface appearance of the steel plate is improved is provided to differentiate a look of the hot-dipped aluminum plating steel plate by cooling and spraying metal powder on the surface of a plated steel plate with the air.;CONSTITUTION: A method for manufacturing hot-dipped aluminum plating steel plate of which surface appearance of the steel plate comprises the following steps: plating a steel plate after dipping the steel plate on molten metal; spraying metal powder on the surface of the plated steel plate with the air; and cooling the steel plate. The metal powder is aluminum powder or alumina powder.;COPYRIGHT KIPO 2010
