Ironmaking process for reducing energy consumption of HIsmelt process by efficiently utilizing sintering return mine

The invention discloses an ironmaking process for reducing energy consumption of an HIsmelt process by efficiently utilizing sintered return mine, and belongs to the technical field of metal smelting. The method comprises the following steps: preheating and pre-reducing the sintered return mine, and then blowing the sintered return mine and pulverized coal into an HIsmelt smelting reduction furnace according to a certain proportion for smelting reduction ironmaking. By means of the iron-making process, efficient utilization of the sintered return mine can be achieved, raw materials such as limestone and dolomite in the HIsmelt process are prevented from being directly fed into the furnace, heat consumption of the HIsmelt smelting reduction furnace is reduced, the reduction rate of the iron-containing materials is increased, energy consumption of the HIsmelt process is reduced, and the iron-making process has important application and popularization value. 本发明公开了一种高效利用烧结返矿降低HIsmelt工艺能耗的炼铁工艺，属于金属冶炼技术领域。本发明将烧结返矿
