Embodiment 1
[0037] The production method of super-thick material layer oxygen-enriched sintering comprises the following steps:
[0038] 1) The sintering raw materials and fuel are mixed and granulated to form sintering mixture A, and calcium permanganate solution is added during the first mixing and granulation, wherein 62% of the calcium permanganate solution is in Add in the first mixing, and add 38% calcium permanganate solution in the second mixing granulation; the weight percentage of the sintered mixture A with a particle size greater than 3mm is controlled at 72%, the moisture is controlled at 6.1%, and the alkalinity is controlled at 1.9; The calcium permanganate solution is prepared by completely dissolving calcium permanganate with 0.6% of the total mass of the sintering mixture A in water.
[0039] 2) The sintering raw material and fuel are mixed and granulated once to form sinter mixture B, and calcium permanganate solution is added during the first mixing and granulated, whe...
