표면외관 및 도장성이 우수한 용융 Al-Zn계 도금강판의 제조방법
Abstract:
표면외관및 도장성이우수한용융 Al-Zn계도금강판의제조방법이개시된다. 본발명의일 측면인표면외관및 도장성이우수한용융 Al-Zn계도금강판의제조방법은중량%로, 아연(Zn): 35~55%, 실리콘(Si): 0.5~3.0%, 잔부알루미늄(Al) 및불가피한불순물을포함하는 Al-Zn계도금욕을준비하는단계; 상기 Al-Zn계도금욕에소지강판을침지하고, 도금을행하여용융 Al-Zn계도금강판을제조하는단계; 및상기용융 Al-Zn계도금강판을냉각하는단계를포함하며, 상기냉각시, 용융 Al-Zn계도금강판의표면에입자크기가 18~32㎛인알루미늄분말을 40~80g/m/min의속도로분사하는것을특징으로한다.
Abstract(Chinese):

公开了一种制造具有优异外观和可涂装性的Al-Zn基镀覆钢板的方法。 本发明的一个方面的制造具有优异的外观和可喷涂性的Al-Zn系镀覆钢板的方法包括：制备包含35-55wt％锌（Zn ），0.5-3.0重量％的硅（Si），其余由铝（Al）和不可避免的杂质组成; 通过将钢板基材料浸渍并镀覆到Al-Zn基电镀浴中来制造Al-Zn基电镀钢板的步骤; 以及冷却熔融的Al-Zn系镀覆钢板的工序。 在冷却步骤中，以40-80g / m 2 / min的速度将熔融的Al-Zn基镀覆钢板的表面上注入了粒径为18-32μm的铝粉末。

Abstract(English):

Method of producing a surface appearance and paintability is excellent in melt-Al-Zn system coated steel sheet is disclosed. One side of the surface appearance and paintability method of producing a superior molten Al-Zn-based plated steel sheet of the present invention is by weight%, zinc (Zn): 35 ~ 55%, silicon (Si): 0.5 ~ 3.0%, the balance aluminum step of preparing the Al-Zn-based plating bath containing (Al) and unavoidable impurities; Step for preparing the Al-Zn, and dipping the steel sheet based on the possession of the plating bath, the plating subjected to molten Al-Zn-based plated steel sheet; And a step for cooling the molten Al-Zn-based plated steel sheet, wherein upon cooling, the molten Al-Zn aluminum powder of particle size of 18 ~ 32㎛-based coated steel sheet to the surface of 40 ~ 80g / m 2 / min and it characterized in that the injection rate.
