Embodiment 1

[0029] S1: Feeding, add 39kg of A00 aluminum ingot, 2.32kg of 533 silicon material (4 / 5 of the overall silicon material used) and 0.17kg of iron agent into the test furnace, ignite and heat up to melt, and control the temperature in the test furnace at 580-590 between ℃. When feeding, small materials that are easy to oxidize, such as silicon and iron, are added to the bottom of the furnace, and large materials that are not easy to oxidize, such as aluminum ingots, are added to the upper part. When adding silicon material, place the feeding platform at the furnace mouth, pour metal silicon on the feeding platform, slowly push the silicon into the aluminum water with a rake, and stir fully so that the silicon is completely immersed in the aluminum water. Stir the liquid to confirm whether the metal silicon is completely melted.
