Abstract:
(EN) The purpose of the present invention is to provide a method for manufacturing a black plated steel sheet that is capable of more evenly blackening the area of the plated steel sheet to be blackened. The present invention relates to a method for manufacturing a black plated steel sheet by bringing a plated steel sheet with an Al- and Mg-containing hot-dip galvanized layer containing Al and Mg into contact with water vapor inside a sealed vessel. This method performs, in the following order: a first step for heating a plated steel sheet disposed inside a sealed vessel in the presence of a gas, the dew point of which is always less than the plated steel sheet temperature; a second step for evacuating the heated ambient gas inside the sealed vessel to make the pressure of the gas inside the sealed vessel to be 70 kPa or less; and a third step for introducing water vapor inside the sealed vessel in which the pressure of the gas therein has been reduced to 70 kPa or less to blacken the galvanized layer.
(FR) L’objectif de la présente invention est de fournir un procédé de fabrication d’une tôle d’acier plaquée noire qui permet de noircir plus uniformément la surface de la tôle d’acier plaquée devant être noircie. La présente invention concerne un procédé de fabrication d’une tôle d’acier plaquée noire par mise d’une tôle d’acier plaquée avec une couche galvanisée à chaud contenant Al et Mg en contact avec de la vapeur d’eau à l’intérieur d’une cuve scellée. Ce procédé effectue, dans l’ordre suivant : une première étape pour chauffer une tôle d’acier plaquée disposée à l’intérieur d’une cuve fermée en présence d’un gaz, dont le point de rosée est toujours inférieur à la température de la tôle d’acier plaquée ; une deuxième étape pour évacuer le gaz ambiant chauffé à l’intérieur de la cuve scellée pour amener la pression du gaz à l’intérieur de la cuve scellée à être de 70 kPa ; et une troisième étape pour introduire de la vapeur d’eau à l’intérieur de la cuve scellée, la pression du gaz dans celle-ci ayant été réduite à 70 kPa pour noircir la couche galvanisée.
(JA) 本発明は、めっき鋼板の黒色化すべき領域をより均一に黒色化できる、黒色めっき鋼板を製造する方法を提供することを目的とする。本発明は、AlおよびMgを含有する溶融Al、Mg含有Znめっき層を有するめっき鋼板を密閉容器の内部で水蒸気に接触させて黒色めっき鋼板を製造する方法に関する。本発明の方法は、密閉容器の内部に配置した前記めっき鋼板を、露点が常にめっき鋼板温度未満であるガスの存在下で加熱する第1工程と、前記加熱された密閉容器の内部の雰囲気ガスを排気して、前記密閉容器の内部の気体の圧力を70kPa以下にする第2工程と、前記内部の気体の圧力を70kPa以下にした密閉容器の内部に水蒸気を導入して前記めっき層を黒色化する第3工程とを、この順番で行う。
