Abstract
Description
(1)搬送されている高温金属に向けてマイクロバブルを含有した冷却液を供給して、前記冷却液により前記高温金属を冷却することを特徴とする高温金属の冷却方法。
前記冷却を、上記(3)に記載の高温金属の冷却方法を用いて行うことを特徴とする溶融亜鉛めっき鋼帯の製造方法。
図1〜図4に示す連続合金化溶融亜鉛めっき設備を用いて、種々の条件で溶融亜鉛めっき鋼帯を製造した。当該設備に、板厚1.2mm×板幅1000mmの焼鈍後の鋼帯を表1に示すライン速度で通板した。溶融亜鉛めっき浴に鋼帯を浸漬し、ガスワイピングで亜鉛付着量を50g/m2となるように調整した後、ミスト冷却装置で冷却して、表1に示す組成のめっき層の溶融亜鉛めっき鋼帯を得た。めっき浴の温度は、めっき組成に応じた適正値に調整し、表1に示した。本実施例では溶融亜鉛めっきの加熱合金化は行わなかった。排気ファンは、ダンパの連結部に一台設け、風量は3600m3/hrの一定出力で運転した。
マイクロバブル含有冷却水のノズルヘッダへの移送方式を変更した点以外は、発明例No.1と同じ条件及び方法で、発明例No.22,23として溶融亜鉛めっき鋼帯を製造した。めっき層組成及び浴温は、発明例No.1であり、Al:0.2質量%、Zn:残部の組成で、460℃とした。
