摘要: The present invention provides a method for manufacturing more beautiful black coated steel sheets by uniformly blackening the coating layer. Specifically, the present invention provides a method for manufacturing black coated steel sheets, which brings Zn—Al—Mg alloy coated steel sheets (1) into contact with steam in a closed container (10), wherein said closed container (10) can maintain a predefined internal pressure through variable control of the amount of steam flowing into said closed container (10) and/or the amount of steam flowing out of said closed container (10), and in said closed container (10) that can maintain said predefined pressure, said Zn—Al—Mg alloy coated steel sheets (1) have contact with the steam introduced into said closed container (10).

摘要: The present invention enables quick cooling of steam-treated objects and thus reduces the manufacturing time of steam-treated products such as black coated steel sheets. The present invention provides a method for manufacturing steam-treated products, which involves a steam treatment step that introduces steam into a closed container (10) containing a treatment object (1) and brings the treatment object (1) into contact with the steam, and a treated object cooling step that cools the object (1) treated with steam in the steam treatment step, wherein said treated object cooling step introduces coolant gas into said closed container (10), brings said treated object (1) into contact with the coolant gas, and discharges the introduced coolant gas from said closed container (10).
