METHOD AND DEVICE FOR MANUFACTURING STEAM-TREATED PRODUCT

The purpose of the present invention is to reduce the time for manufacturing a steam-treated product such as a blued steel sheet by quickly cooling an object after steam treatment. A method for manufacturing the steam-treated product involves a steam treatment step for introducing steam into an airtight container 10 in which an object 1 to be treated is placed, thereby bringing into contact the steam and the object 1 to be treated, and a treated object cooling step for cooling the object 1 treated in the steam treatment step, and is characterized in that the treated object cooling step is a step in which cooling gas is introduced into the airtight container 10 thereby causing the cooling gas to come into contact with the object 1 treated, and the introduced cooling gas is vented from the airtight container 10. 水蒸气处理制品的制造方法及制造装置。本发明通过将水蒸气处理后的被处理物迅速冷却以缩短黑色镀覆钢板等水蒸气处理制品的制造时间。本发明是一种水蒸气处理制品的制造方法，包括：水蒸气处理步骤，向内部配置有被处理物(1)的密闭容器(10)内导入水蒸气，使该水蒸气与被处理物(1)接触；以及被处理物冷却步骤，使在水蒸气处理步骤中进行了水蒸气处理的被处理物(1)冷却；水蒸气处理制品的制造方法的特征在于：被处理物冷却步
