| description | The invention discloses a method for reducing aluminum element segregation in a hot-dip galvanizing alloy large ingot, and belongs to the technical field of alloy material production. The method comprises the following steps: firstly, refining and slagging a molten electrolytic zinc sheet or zinc ingot, then adding a zinc-aluminum intermediate alloy and fully stirring, and then sampling and sending a qualified sample to prepare a condensed alloy block; and secondly, secondary casting is adopted at the specified furnace temperature and mold temperature, and the condensation alloy block prefabricated in the third step is inserted into the center position of the alloy ingot in the gap between the first casting and the second casting. And after the condensed alloy block is gradually melted, the upper hanging ring is taken out. And after the alloy liquid is completely cooled, a large amount of water is immediately adopted for cooling. According to the method, directional migration of alloy elements caused by speci |
