The invention discloses a method for quantitatively ladling a metallic solution with a ladle and a method for ensuring the safe working height of the ladle in the metallic solution. Compared with theprior art, the method for quantitatively ladling the metallic solution with the ladle comprises the following steps that a solution inlet and outlet of the ladle is rotated downwards, so that an included angle of -T degrees is formed between the ladle and the horizontal plane; the ladle stops descending after vertically descending by a distance C, and the metallic solution starts to enter the ladle from the solution inlet and outlet; and after D time, a first quantitative amount X of metallic solution flows into the ladle. According to the method for quantitatively ladling the metallic solution with the ladle and the method for ensuring the safe working height of the ladle in the metallic solution, a fixed amount of metallic solution can be quickly obtained, the efficiency of ladling the solution into the ladle is improved, and the production efficiency is improved.
