本发明提供的一种耐黑变性能优异的高表面质量锌铝镁钢板及生产方法。与现有技术相比，本发明在镀液中添加Si、Ti和Cu，配合浸镀、镀后冷却、光整等工艺，产品锌渣较少，镀层晶粒尺寸细化，具有优异的耐黑变性能和耐蚀性能，同时具有优异的表面质量和加工成型性能。

The invention provides a high-surface quality zinc-aluminum-magnesium steel plate with excellent blackening resistance and a production method.Compared with the prior art, Si, Ti and Cu are added into the plating solution; a product has little zinc slag by matching the processes of immersion plating, cooling after plating, finishingand the like; the grain size of a plated layer is refined; and the high-surface quality zinc-aluminum-magnesium steel plate has excellent blackening resistance and corrosion resistance, and meanwhile,has excellent surface quality and processing and forming performance.
