一种酸性球团矿和碱性物料混合超厚料层烧结技术
摘要：
本发明提供了一种新型的酸性球团和碱性物料混和超厚料层烧结技术。此种烧结技术含有以下组分：5～8mm酸性球团矿(生球)为3％～8％，8～10mm酸性球团矿(生球)为10％～15％，10～12.5mm酸性球团矿(生球)为15％～25％，>12.5mm酸性球团矿(生球)为2％～5％，碱性物料含量为50％～70％(重量按100％计)。本发明一方面能够改善烧结料层透气性，加强氧化气氛，提高烧结矿料层厚度，达到提高产、质量，节省能源的目的；另一方面能够充分利用烧结过程热量，生产适宜碱度的烧结矿，缩短了生产流程，增加了生产经济效益。因此可推测此种新型酸碱混和超厚料层烧结技术，能够改善料层的透气性，加厚烧结料层，强化氧化性气氛，有效地提高烧结机利用系数，从而使烧结生产达到节省能耗，提高烧结产质量的目的。
摘要（英）：

The invention provides a novel sintering technology for an acidic pellet and alkaline material mixed ultra-thick material layer. The sintering technology contains the following components: 3%-8% of an acidic pellet ore (green ball) with the particle size of 5-8 mm, 10%-15% of an acidic pellet ore (green ball) with the particle size of 8-10 mm, 15%-25% of an acidic pellet ore (green ball) with the particle size of 10-12.5 mm, 2%-5% of an acidic pellet ore (green ball) with the particle size of greater than 12.5 mm, and 50%-70% of an alkaline material (according to the weight percentage). On one hand, the air permeability of a sintered material layer can be improved, the oxidizing atmosphere is strengthened, the thickness of the sintered material layer is increased, and the purposes of improving production and quality and saving energy are achieved; and on the other hand, heat in the sintering process can be fully utilized, a sintered ore with suitable basicity is produced, the production process is shortened, and the production economic benefit is increased. Therefore, the novel acid and alkali mixed ultra-thick material layer sintering technology can be speculated to be capable of improving the air permeability of the material layer, thickening the sintered material layer, strengthening the oxidizing atmosphere and effectively improving the utilization coefficient of a sintering machine, so as to allow sintering production to achieve the purposes of saving energy consumption and improving the sintering quality.
