[0045] Example 1: Preparation of the aluminum-zinc-magnesium coated steel sheet of the present invention
[0046] (1) Without stopping the equipment, add 2.2 tons of magnesium alloy ingot A to 90 tons of zinc liquid in the main pot at a temperature of 593°C, and melt for 72 hours to obtain mixed plating bath A; to the pre-melting pot at a temperature of 593°C ( The pre-melting pot is connected with the main pot and is used to add 55 tons of magnesium alloy ingot B and aluminum-zinc ingots to the main pot (the amount of addition is to adjust the composition of the main pot plating solution to the following aluminum-zinc-magnesium The component content percentage of the plating solution), and melt for 72 hours to obtain a mixed plating solution B; after the mixed plating solution A and the mixed plating solution B are uniformly mixed, the aluminum-zinc-magnesium plating solution is obtained. Wherein, in terms of mass percentage, the zinc solution contains: Al 53, Si≤0.2%, the balan...

[0050] Example 2: Preparation of the aluminum-zinc-magnesium coated steel sheet of the present invention
[0051] (1) Without stopping the equipment, add 2.2 tons of magnesium alloy ingot A to the 90 tons of zinc solution in the main pot at a temperature of 597℃, and melt for 96h to obtain a mixed plating solution A; to the pre-melting pot at a temperature of 597℃ ( The pre-melting pot is connected with the main pot and is used to add 55 tons of magnesium-containing alloy ingot B and aluminum-zinc ingot (the amount of addition is to adjust the plating solution to the composition content of the aluminum-zinc-magnesium plating solution described below) ), melting for 96 hours to obtain a mixed plating solution B; after mixing the mixed plating solution A and the mixed plating solution B uniformly, the aluminum-zinc-magnesium plating solution is obtained. Wherein, in terms of mass percentage, the zinc solution contains: Al 55, Si≤0.2%, the balance being zinc and other inevitable im...
