Iron ore low-carbon sintering method

The invention belongs to the field of steel smelting, and particularly relates to an iron ore low-carbon sintering method which is low in sintering energy consumption. According to the technical scheme, the iron ore low-carbon sintering method includes the steps that iron ore, fuel and a fluxing agent are distributed and mixed to form a mixture for sintering, wherein magnetite in the iron ore is not smaller than 50% by mass, non-magnetite m1 is greater than 0 but smaller than or equal to 40%, metallurgy waste m2 is greater than or equal to 0 but smaller than or equal to 10%, the non-magnetite is at least one of hematite, limonite and siderite, and the metallurgy waste is iron waste mainly composed of Fe and FeO. According to the method, raw material constitutes of the mixture and technical parameters are adjusted, so that non-carbon heat input is increased, carbon content is reduced, and sintering energy consumption is reduced.
