Embodiment 1
[0025] Embodiment 1 (preparation inoculant)
[0026] By weight percentage, 66% Si, 10% Ba, 2% Ca, 1.8% Al, 1.5% Ce, 1% S, 0.5% recarburizer and 17.2% Fe are mixed evenly and put in In a vacuum electric furnace, replace the air in the furnace with argon, raise the temperature to 1300°C, and smelt for 5 minutes. Stir continuously during the smelting process to mix the raw materials evenly; pour in a container, and place the container in liquid nitrogen to make the alloy raw material Rapidly cool to room temperature to form a block, and the block is crushed into an alloy powder with an average particle size of 10 μm; 3 o 4 Add the powder into the mixing container and mix it with alloy powder and Fe 3 o 4 The sodium silicate solution of 5% of the total weight of the powder is added together into a roller compacting device to form agglomerates, and finally crushed to an average particle size of 50 μm. Wherein, the components of the recarburizer include: C: 99%, S: 0.4, moisture...
Embodiment 2
[0027] Embodiment 2 (preparation inoculant)
[0028] By weight percentage, 72% Si, 3% Ba, 1% Ca, 0.8% Al, 2% Ce, 1% recarburizer and 20.2% Fe are mixed evenly and placed in a vacuum electric furnace. Replace the air in the furnace with argon, raise the temperature to 1500°C, and smelt for 10 minutes. Stir continuously during the smelting process to mix the raw materials evenly; pour in a container, and place the container in liquid nitrogen to rapidly cool the alloy raw materials to room temperature. Form a block, crush the block into an alloy powder with an average particle size of 30 μm; the obtained above-mentioned alloy powder and an average particle size of 30 μm are 0.5% by weight of Fe 3 o 4 Add the powder into the mixing container and mix it with alloy powder and Fe 3 o 4 The sodium silicate solution of 3% of the total weight of the powder is added together into a roller compacting device to form agglomerates, and finally crushed to an average particle size of 100 μ...
Embodiment 3
[0029] Embodiment 3 (preparation inoculant)
[0030] By weight percentage, 68% Si, 8% Ba, 1.6% Ca, 1% Al, 1.6% Ce, 0.8% S, 0.6% recarburizer and 18.4% Fe are mixed evenly and put into In a vacuum electric furnace, replace the air in the furnace with argon, raise the temperature to 1400°C, and smelt for 6 minutes. Stir continuously during the smelting process to mix the raw materials evenly; pour in a container, and place the container in liquid nitrogen to make the alloy raw material Cool rapidly to room temperature to form a block, and the block is crushed into an alloy powder with an average particle size of 20 μm; the above-mentioned alloy powder obtained and an average particle size of 1% Fe 3 o 4 Add the powder into the mixing container and mix it with alloy powder and Fe 3 o 4 The sodium silicate solution of 3% of the total weight of the powder is added together into a roller compacting device to form agglomerates, and finally crushed to an average particle size of 60...
