Embodiment 1
[0025] The inoculants generally described in this embodiment include 35 parts by mass of ferrosilicon, 18 parts of nano-silicon carbide, 8 parts of calcium silicon, 7 parts of pure aluminum, 7 parts of zirconium silicate, and 14 parts of rare earth silicon aluminum alloy (the The mass ratio between the rare earth silicon aluminum alloy, pure aluminum and zirconium silicate is 2:1:1). Its concrete preparation method is:
[0026] Step 1. Weigh 35 parts by mass of ferrosilicon and 7 parts of pure aluminum and mix them, and store them in a mixing container after mixing; the 7 parts of pure aluminum are first dissolved and dissolved at a high temperature of 700~750°C, After dissolving, the solution is poured into the ferrosilicon, and the ferrosilicon is placed in the suspended elastic plate 1, such as figure 1 As shown, when the ferrosilicon dissolves into the pure aluminum liquid, it falls into the bottom of the mixing container;
[0027] Step 2, placing nano-silicon carbide un...
Embodiment 2
[0040] The inoculants generally described in this embodiment include 30 parts by mass of ferrosilicon, 10 parts of nano-silicon carbide, 7 parts of calcium silicon, 6 parts of pure aluminum, 6 parts of zirconium silicate, and 12 parts of rare earth silicon aluminum alloy (the The mass ratio between the rare earth silicon aluminum alloy, pure aluminum and zirconium silicate is 2:1:1). Its concrete preparation method is:
[0041] Step 1. Weigh 30 parts by mass of ferrosilicon and 6 parts of pure aluminum and mix them, and store them in a mixing container after mixing; the 6 parts of pure aluminum are first dissolved and dissolved at a high temperature of 700~750°C, After dissolving, the solution is poured into the ferrosilicon, and the ferrosilicon is placed in the suspended elastic plate 1, and when the ferrosilicon dissolves into the pure aluminum liquid, it falls into the bottom of the mixing container;
[0042] Step 2, placing nano-silicon carbide under the mixing container...
Embodiment 3
[0047] The inoculants generally described in this embodiment include 50 parts by mass of ferrosilicon, 20 parts of nano-silicon carbide, 12 parts of calcium silicon, 10 parts of pure aluminum, 10 parts of zirconium silicate, and 20 parts of rare earth silicon aluminum alloy (the The mass ratio between the rare earth silicon aluminum alloy, pure aluminum and zirconium silicate is 2:1:1). Its concrete preparation method is:
[0048] Step 1. Weigh 50 parts by mass of ferrosilicon and 10 parts of pure aluminum and mix them, and store them in a mixing container after mixing; the 10 parts of pure aluminum are first dissolved and dissolved at a high temperature of 700~750°C, After dissolving, the solution is poured into the ferrosilicon, and the ferrosilicon is placed in the suspended elastic plate 1, and when the ferrosilicon dissolves into the pure aluminum liquid, it falls into the bottom of the mixing container;
[0049] Step 2, placing nano-silicon carbide under the mixing cont...
