PROBLEM TO BE SOLVED: To provide a steam treatment method capable of improving production efficiency of a black plated steel sheet or the like by heating a treatment object such as a plated sheet steel or the like in a short time in comparison with a case of using an electric heater.SOLUTION: A steam treatment method for bringing a treatment object 1 into contact with steam in a closed vessel 10, includes a treatment object heating step for heating the treatment object 1 by heating the closed vessel 10 by a gas burner 24 between the closed vessel 10 having the treatment object 1 arranged inside and an outer vessel 11 for covering the closed vessel 10 at a prescribed interval from the closed vessel 10, and a steam treatment step for introducing steam into the closed vessel 10, so that steam is brought into contact with the treatment object 1, after the treatment object heating step.SELECTED DRAWING: Figure 2 【課題】電気ヒータを用いる場合と比べてめっき鋼板等の被処理物を短時間で加熱して、黒色めっき鋼板等の生産効率を向上させることができる水蒸気処理方法を提供する。【解決手段】被処理物１を密閉容器１０中で水蒸気と接触させる水蒸気処理方法であって、被処理物１が内部に配置された密閉容器１０と、密閉容器１０と所定の間隔を空けて密閉容器１０を覆う外側容器１１との間で密閉容器１０をガスバーナ２４で加熱し、被処理物１を加熱する被処理物加熱工程と、被処理物加熱工程の後に、密閉容器１０内に水蒸気を導入し、水蒸気と、被処理物１とを接触させる水蒸気処理工程とを備える。【選択図】図２
