镀锌钢板的制造方法
摘要：
一种镀锌钢板的制造方法，首先对钢板表面进行清洁处理；然后采用冷气动力喷涂技术在钢板上制备锌镀层形成镀锌板；然后带有镀锌层的钢板经平整或冷轧得到镀锌层均匀致密，高表面质量镀锌钢板，再经合金化处理提高镀层与基板的结合力。本发明可制备普通及特殊成分、复合金属镀锌层、复合陶瓷与金属镀锌层以及镀锌层梯度过渡的镀锌钢板，且可以制备任意厚度镀锌钢板。制备技术对基材无热影响及腐蚀，生产效率高、流程短、无污染、镀层表面质量高。
摘要（英）：

The invention discloses a preparing method of galvanized steel sheet, which comprises the following steps: cleaning the surface of the metal plate; preparing zinc coating on the steel sheet with cool air dynamic spraying technique; forming galvanized sheet; flattening; cool-rolling; getting the galvanized steel sheet with compact zinc coating and high quality surface; alloying; increasing bindingforce of coating and base plate. This invention can prepare galvanized steel sheet with arbitrary thickness, which possesses high productive efficiency, short flow process and high quality of coatingsurface.
