Embodiment 1
[0032] Weigh 20g of aluminum sulfate into 100g of water to prepare a binder solution for later use. Weigh 1000 g of fine-grained high-titanium slag (particle size less than 150 μm) and place it in a high-speed stirring granulator. The speed of the stirring paddle is 300 rpm, and the stirring time is 2 minutes. Stir well. The prepared binder solution is evenly sprayed into the material by the spray gun of the high-speed mixer for granulation treatment. The granulated product particles are placed in a fluidized bed dryer for drying, and the particle size distribution is between 150 and 1000 μm, accounting for 85%, the particle cold strength wear index is 5.67%, and the particle hot strength wear index is 2.80%.
[0033] The particle wear index experiment shows that the wear index of particle cold strength is 5.67%, which proves that the prepared particles have good cold strength and can meet the requirements of material transportation and furnace strength. After the heat treatm...
Embodiment 2
[0035]Weigh 30g of aluminum sulfate into 100g of water to prepare a binder solution for later use. Weigh 1000 g of fine-grained high-titanium slag (particle size less than 150 μm) and place it in a high-speed stirring granulator. The stirring paddle rotates at 300 rpm and the stirring time is 2 minutes. The prepared binder solution is uniformly sprayed into the material by the spray gun of the high-speed mixer for granulation treatment. The granulated product particles are placed in a fluidized bed dryer for drying, and the particle size distribution is between 150 and 1000 μm, accounting for 90%, the particle cold strength wear index is 4.36%, and the particle hot strength wear index is 1.76%.
[0036] The particle wear index experiment shows that the wear index of particle cold strength is 4.36%, which proves that the prepared particles have good cold strength and can meet the requirements of material transportation and furnace strength. After heat treatment, the wear index...
Embodiment 3
[0038] Weigh 20g of aluminum sulfate into 120g of water to prepare a binder solution for later use. Weigh 1000 g of fine-grained high-titanium slag (particle size less than 150 μm) and place it in a high-speed stirring granulator. The stirring paddle rotates at 300 rpm and the stirring time is 2 minutes. The prepared binder solution is uniformly sprayed into the material by the spray gun of the high-speed mixer for granulation treatment. The granulated product particles were placed in a fluidized bed dryer to dry, and the particle size distribution was between 150 and 1000 μm, accounting for 92%, the particle cold strength wear index was 4.98%, and the particle hot strength wear index was 2.13%.
[0039] The particle wear index experiment shows that the wear index of particle cold strength is 4.98%, which proves that the prepared particles have good cold strength and can meet the requirements of material transportation and furnace strength. After heat treatment, the wear inde...
