Description
本願は、2011年09月22日に、日本に出願された特願2011−208118号に基づき優先権を主張し、その内容をここに援用する。
(1)本発明の一態様は、溶融めっき浴から引き上げられる鋼板を挟んで、両側に前記鋼板の板面に向かってそれぞれ配置された一対のワイピングノズルから、ワイピングガスを前記鋼板に吹き付けるワイピング装置であって、前記一対のワイピングノズル間の前記鋼板の幅方向の両側に、前記鋼板と平行にそれぞれ配置され、エアーを吸引する吸込口が前記鋼板の側端面に向かって配置され、断面形状が前記鋼板の引き上げ方向に幅広である吸引管を備え、前記吸引管は、断面の短辺に対する長辺の比が1.2〜10である。
4:Pe/Pc>0.9、
3:0.8≦Pe/Pc≦0.9、
2:0.6≦Pe/Pc<0.8、
1:0.6>Pe/Pc
を示す。4段階表示で数値が大きいほど、エッジオーバーコート改善効果が大きいとする。また、メタル付着状況は、3段階表示で、
3:メタル付着なし、
2:メタルは付着するが、長時間操業が可能、
1:メタル付着により長時間操業が不可能
を示す。
以上の知見から、吸引管の長辺長さは15mm〜50mmとし、断面の短辺に対する長辺の比が1.2〜10を最適形状とした。なお、吸引管の最適形状について、オーバーコート改善に必要な衝突ガス圧力比(Pe/Pc)の目標に応じて異なるため、前記と同等の効果が得られた場合は、全て本発明と同様の効果とすべきである。
