锌花通常指热镀锌板从锌锅拉出后，随着锌层冷却凝固后形成的晶粒的外观表现。锌花的尺寸大小、亮度和表面形貌取决于一系列因素，但主要与锌层成分和冷却方法有关。产生锌花的原理是设法降低锌液的凝固温度。
结果表明，热镀梓板有典型的锌花形貌，明亮和灰暗锌花区的形貌差异大；
Results show that hot galvanizing plate has typical spangle appearance, and the appearances distinguish in bright zone and gray zone.
一种铝锌硅热镀钢板生产线的锌花控制方法，属于高耐蚀镀层生产技术领域。
The invention discloses a spangle control method for an aluminum zinc silicon hot-dipped steel plate production line, and belongs to the technical field of high-anticorrosive plating production.
正常凝固态时生产出锌花尺寸较大、大小均匀的大锌花产品。快速凝固时形成大小均匀，色泽一致的小锌花产品。同时还可降低锌液温度，减少了锌锅和其它机件的腐蚀，延长了设备寿命。
Its advantages are large-size and uniform zinc pattern on normal settling or small zinc pattern with uniform lustre on quick settling, lower temp of molten zinc, and long service life of equipment.
