Fibrous MgO and SiO2-containing flux for sintering

The invention discloses a fibrous flux containing MgO and SiO2 for sintering, the flux contains MgO and SiO2, the flux is used for replacing the current serpentine with high content of MgO and high content of SiO2 for sintering according to a certain proportion, and sintering burdening, uniform mixing, granulation, material distribution and sintering are carried out to finally obtain sintered ore. The invention aims to provide the fibrous flux containing MgO and SiO2 for sintering, which can be used for replacing the current serpentine with high content of MgO and high content of SiO2, and can effectively reduce the sintering burdening cost under the condition of ensuring that the quality index of sintered ore meets the smelting requirement of a blast furnace. 本发明公开了一种烧结用纤维状含MgO、SiO2熔剂，该熔剂含有MgO和SiO2，将该熔剂按照一定的比例替代当前烧结用高含量MgO、高含量SiO2蛇纹石，经烧结配料、混匀、制粒、布料、烧结，最终得到烧结矿。本发明的目的是提供一种烧结用纤维状含MgO、SiO2熔剂，可以用于替代当前用高含量MgO、高含量SiO2蛇纹石，在保证烧结矿质量指标满足高炉冶炼要求的条件下，可有效降低烧结配料成本。
