[0002] With the advancement of blast furnace ironmaking technology, the requirements for sinter quality are becoming increasingly stringent, encompassing the entire technical and economic aspects. Against this backdrop, traditional ore blending techniques based on the room-temperature characteristics of iron ore powder can no longer effectively meet the needs of sintering production and blast furnace smelting. Ironmaking workers are eager for more efficient sintering ore blending techniques. Different types of iron ore have different fundamental sintering characteristics. Understanding and applying these characteristics can clarify the "black box" between iron ore type and sintering effect, thus playing a crucial role in perfecting the basic theory of sintering concentrates, implementing autonomous optimization of sintering ore blending, and optimizing the sintering process. During blast furnace ironmaking, it is necessary to add iron ore powder to the equipment.

[0003] Existing iron ore powder feeding methods have high feed concentration and poor uniformity, which affects the sintering blending effect and thus the blast furnace ironmaking efficiency. To address this, we propose an iron ore powder adding device for sintering blending. Utility Model Content
