Embodiment 1
[0021] Mix 180Kg of dust, 60Kg of coke powder, 20Kg of Mukang, and 740Kg of manganese ore powder evenly, and put them into sintering boxes, each sintering box is 100Kg, and then send it into a box-type sintering machine, and sinter at 900°C for 30 minutes to obtain large pieces Sintered agglomerates, crushed, sieved, and small pieces with a particle size of 10mm to 80mm are used as raw materials for silicon-manganese alloys. Particles smaller than 10mm are returned to the ore and re-sintered to make agglomerates.
Embodiment 2
[0023] Mix 200Kg of dust, 70Kg of coke powder, 30Kg of Mukang, and 700Kg of manganese ore powder evenly, and put them into a sintering box, each sintering box is 100Kg, and then send it into a box-type sintering machine, and sinter at 900°C for 30 minutes to obtain a large block Sintered agglomerates, crushed, sieved, and small pieces with a particle size of 10mm to 80mm are used as raw materials for silicon-manganese alloys. Particles smaller than 10mm are returned to the ore and re-sintered to make agglomerates.
Embodiment 3
[0025] Mix 200Kg of dust, 80Kg of coke powder, 20Kg of peanut shell powder, and 700Kg of manganese ore powder evenly, and put them into a sintering box. Obtain a large sintered block, crush it, sieve it, and use it as a raw material for the silicon-manganese alloy. Particles smaller than 10 mm are returned to the ore and re-sintered to form a block.
