Embodiment 1
[0043] The method for preparing ferrosilicon alloy by feeding aluminum ash as a raw material hollow electrode comprises the following steps:
[0044] Step 1, making aluminum ash, waste cathode carbon block, fly ash and diatomite waste slag in aluminum electrolytic cell overhaul slag into powder respectively, and the particle size is all less than 100 mesh;
[0045] Step 2, according to the composition of the target aluminum-silicon-ferroalloy: 28% aluminum content, 61% silicon content, and the rest are iron, calcium, titanium and other trace metals, using the fixed carbon contained in the waste cathode carbon block as the reducing agent according to chemical The metering ratio is used to calculate the mass of secondary aluminum ash, spent cathode carbon block, fly ash and diatomite waste slag required for the reduction of metal oxides, wherein the metal aluminum in the secondary aluminum ash is calculated as if all of it enters the Al-Si-Fe alloy, and the nitriding All the alu...
