Rapid, accuracy and compact aluminum alloy burden calculation method

The invention relates to a rapid, accurate and simple aluminum alloy feed proportioning calculation method, which is characterized in that the amount of solute and solvent are magnified or minified in a same proportion according to the proportion relation between the solute and the solvent, and the ratio does not change; when the chemical composition requirements of aluminum alloy are given, the proportion of every element is selected, then the proportion coefficient of every alloy element is solved according to the proportion relation between the alloy element and pure aluminum, and the required feed amount of every element is obtained by proportion coefficient multiplied by aluminum liquid weight and then divided by the percentage content of the element in master alloy. The method is simple, fast and accurate. The operators only need to find out the coefficient according to the production grade and then makes a simple calculation of plus-minus and multiply divide, then the stable and qualified products can
