Method for controlling defects of zinc ash and zinc slag of zinc-aluminum-magnesium product

The invention discloses a zinc ash and zinc slag defect control method for a zinc-aluminum-magnesium product. The method comprises the following steps: constructing a hot-based galvanizing production line; obtaining a strip steel raw material; carrying out cleanliness enhancement operation on the surface of the strip steel; feeding the strip steel into a reaction pot of the hot-based galvanizing production line; the furnace nose of the hot-based galvanization production line is subjected to homogenizing, humidifying and enhancing operation; humidifying parameters in the furnace nose are adjusted; a deslagging furnace nose structure is additionally arranged on the hot-based galvanizing production line; adjusting the components of the zinc liquid in the reaction pot; and adjusting the temperature of the zinc liquid in the reaction pot. According to the method for controlling the zinc ash and zinc slag defects of the zinc-aluminum-magnesium product, the zinc ash and the zinc slag are controlled by adopting a tec
