The formula for calculating this ingredient is: a=g×q÷a÷n-b×a.

The formula for calculating the ingredients for mechanical casting alloy smelting is: a=g×q÷a÷n-b×a. Among them, a represents the weight of a certain alloy material that needs to be added to the casting auxiliary alloy materials (kg), g represents the weight of a single batch of melted alloy materials (kg), q represents the content value of a certain alloy element required for the casting alloy product, and a represents The content percentage value of a certain element required to be added to the smelting alloy material, n represents the absorption rate of element a in the casting alloy during the casting and smelting process, b represents the amount of the main alloy material containing element a in the ingredient list (kg ).
