Embodiment 1
[0033] A method for utilizing crystalline silicon cutting waste in this embodiment includes the following steps:
[0034] Weigh 100 parts by mass of molybdenum calcine, 30 parts of crystalline silicon cutting waste, 8 parts of aluminum particles, 30 parts of iron and phosphorus, 30 parts of steel scrap, 12 parts of quicklime, 4 parts of fluorite, and 3 parts of saltpeter, Carry out mixing and pelletizing in a pelletizer for 10 minutes, and spray 6wt% of water during the process; put the uniformly mixed pellet material into the furnace, the ratio of the height of the charge D to the full height of the furnace is D / H=0.37, and at the top of the charge 5 wt % rice husks are covered; after the reaction is completed, let stand to allow ferromolybdenum to settle, and then open the slag discharge port to discharge slag; finally pull out the furnace drum, and the alloy ingot can be cooled in the sand to obtain the ferromolybdenum alloy. The chemical element analysis shows that the mol...
Embodiment 2
[0036]Weigh 150 parts of molybdenum calcining sand, 40 parts of crystalline silicon cutting waste, 15 parts of aluminum granules, 38 parts of iron and phosphorus, 42 parts of steel scraps, 15 parts of quicklime, 5 parts of fluorite, 5 parts of saltpeter by weight respectively, Carry out mixing and pelletizing in a pelletizer for 13 minutes, and spray 10wt% of water during the process; put the evenly mixed pelletized material into the furnace, the ratio of the height of the charge D to the full height of the furnace is D / H=0.4, and the top of the charge is placed at the top of the furnace. 8 wt% rice husks are covered; after the reaction is finished, let stand to settle the ferromolybdenum, and then open the slag discharge port to discharge the slag; finally pull out the furnace drum, and the alloy ingot can be cooled in the sand to obtain the ferromolybdenum alloy. The chemical element analysis shows that the molybdenum content in the prepared ferromolybdenum is 60.3 wt %, the ...
Embodiment 3
[0038] Weigh 130 parts of molybdenum calcining sand, 37 parts of crystalline silicon cutting waste, 10 parts of aluminum granules, 34 parts of iron and phosphorus, 35 parts of steel scraps, 12 parts of quicklime, 4 parts of fluorite, 5 parts of saltpeter, respectively, in parts by mass, Carry out mixing and pelletizing in a pelletizer for 15 minutes, and spray 7wt% of water during the process; put the uniformly mixed pellet material into the furnace, the ratio of the height of the charge D to the full height of the furnace is D / H=0.39, and the top of the charge is placed at the top of the furnace. 5.4wt% rice husks are covered; after the reaction is finished, let stand to allow ferromolybdenum to settle, and then open the slag discharge port to discharge slag; finally pull out the furnace tube, and the alloy ingot can be cooled in the sand to obtain the ferromolybdenum alloy. The chemical element analysis shows that the molybdenum content in the prepared ferromolybdenum is 58.6...
