The invention relates to a production method capable of improving the grain size of an AlSi7Mg aluminum alloy. The production method comprises the following steps of: melting to obtain AlSi7Mg melts; casting at the temperature of between 635 and 650 DEG C and the speed of between 5 and 8 tons/hour by a pulley type casting process; and dividing a crystallizing wheel into three inner cooling areas, three outer cooling areas, three inside cooling areas and three outside cooling areas, wherein the water flow of an inner cooling area 1 is between 3.5 and 6m<3>/h, the water flow of an inner cooling area 2 is between 19 and 23m<3>/h, and the water flow of an inner cooling area 3 is between 3.5 and 6m<3>/h; the water flow of an outer cooling area 1 is between 2 and 4m<3>/h, the water flow of an outer cooling area 2 is between 19 and 29m<3>/h, and the water flow of an outer cooling area 3 is between 19 and 23m<3>/h; the water flow of an inside cooling area 1 is between 2 and 4m<3>/h, the water flow ...

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 ...
