3228788号公報に代表されている。 As is well known, in the continuous hot-dip galvanizing method, a strip steel strip is heated and activated in a heating furnace maintained in a reducing atmosphere, and then introduced into a molten zinc plating bath and plated on both sides by immersion. On the other hand, a continuous hot-dip galvanizing method in which only one side of a strip steel strip is coated is known as a roll coating method or a flow coating method in a reducing atmosphere, for example, as disclosed in the U.S. Pat.
This is typified by Publication No. 3228788.

発明の範囲を逸脱するものではない。 For convenience of explanation of the present invention, a single-sided plating unit and a double-sided plating unit have been illustrated and described above, and these have been collectively referred to as a plating unit. However, the present invention is not limited to this. For example, Of course, it is possible to selectively exchange units for single-sided plating or units for double-sided plating, and this does not depart from the scope of the present invention.

囲気中の酸素量がO2メーター計量されている。 Furnace pressure is maintained in the atmosphere of the plating unit 9 by the N 2 nozzle 5, and the pressure is constantly detected. The amount of oxygen in the atmosphere is also measured using an O2 meter.
片面めつき用ユニツトを両面めつき用ユニツト
に切替らる場合は、めつき用鋼帯が設備内に通板
されているので、この対策は極めて重要である。 When switching from a single-sided plating unit to a double-sided plating unit, this measure is extremely important since the steel strip for plating is passed through the equipment.
本発明によるとめつき鋼帯の取出と、めつき用
ユニツトの切替交換は次のシーケンスによつて行

めつきラインを停止すると同時に入側シール部
の遮断ダンパー２を全閉して入側シールダンパー
１と併用して加熱炉への空気の侵入を防止する。 At the same time as stopping the plating line, the shutoff damper 2 of the entrance seal part is fully closed and used together with the entrance seal damper 1 to prevent air from entering the heating furnace.
ついでマンホール２３の蓋をとりはずしてめつ
き鋼帯を部分的に巻き戻して板抜きを行う。 Next, the cover of the manhole 23 is removed and the plated steel strip is partially rolled back to perform board cutting.
この状態を模式的に第２図に示した。 This state is schematically shown in FIG.
めつき鋼帯２１の板抜きに当つてはキヤリアロ
