Si：GSi＝100×7.3％＝7.3kg
Mg：GMg＝100×0.35％＝0.35kg
Ti：GTi＝100×0.14％＝0.14kg
Al：GAl＝100-GSi-GMg-GTi＝100-7.3-0.35-0.14＝92.21kg
2) calculate the mass ratio relation (being coefficient) of each alloying element (referring to pure metal) and Al:
The coefficient of Si: GSi/GAl=7.3 ÷ 92.21=0.07917 is similar to and gets 0.079

Should add Si:GSi=0.079 * 14820=1170.8kg
Should add Mg:GMg=0.0038 * 14820=56.3kg
Should add the Ti agent: GTi agent=0.0015 * 14820 ÷ 75%=29.6kg
4) calculate total stove amount:
Total stove amount be G total=GAl+GSi+GMg+GTi agent=14820+1170.8+56.3+29.6=16073.5kg
5) checking computations:
Si％＝1170.8÷16073.5×100％＝7.284％
Mg％＝56.3÷16073.5×100％＝0.35％
Ti％＝29.6×75％÷16073.5×100％＝0.138％
6) judge:
| Sequence number | Alloying element | Target value | The batching value | Absolute error | Relative error | The batching conclusion |
