CN110527823A 一种强化烧结过程的复合添加剂及烧结矿及其制备方法 无效 - 驳回

一种强化烧结过程的复合添加剂及烧结矿及其制备方法
摘要：
本发明属于钢铁冶金烧结技术领域，具体涉及一种强化烧结过程的复合添加剂及烧结矿及其制备方法，按重量百分比计，本发明的强化烧结过程的复合添加剂由0.05％～10％的含硼化合物、0.03％～6％的氧化剂及0.01％～2％聚乙二醇，其余为水，按所述各组分配比配制后，均匀混合而成。将此添加剂以一定比例配入烧结混合料中，配入量为0.5～2kg/t，充分混合制粒，在烧结机中进行布料、点火、烧结，能够有效提高烧结效率，改善烧结矿质量，强化高炉冶炼。
摘要（英）：

The invention belongs to the technical field of ferrous metallurgy sintering, particularly relates to a composite additive for strengthening a sintering process, a sinter and a preparation method thereof. The composite additive for strengthening the sintering process is formed by preparing and uniformly mixing the components of, by weight percentage, 0.05% to 10% of boron-containing compound, 0.03% to 6% of oxidant, 0.01% to 2% of polyethylene glycol and the balance of water. The additive is added into a sintering mixture according to a certain proportion, the adding amount is 0.5-2 kg/t, andthe additive is fully mixed for granulation. The materials are distributed, ignited and sintered in a sintering machine, so that the sintering efficiency can be effectively improved, the quality of sinter is improved, and the blast furnace smelting is strengthened.
