Anhydrous stemming for light iron-making blast furnace and preparation method of anhydrous stemming
The invention provides light anhydrous stemming for an iron-making blast furnace. The light anhydrous stemming comprises a dry material and a binding agent, the dry material comprises the following components in percentage by weight: 15-25% of lightweight aggregate; 8 to 25 wt% of an alumina-based aggregate; 5 to 10 wt% of coke; 10 to 20 wt% of silicon carbide; 10 to 20 weight percent of ferro-silicon nitride; 3 to 10 wt% of an alumina-based fine powder; 3 to 10 weight percent of white mud; 2 to 6 wt% of asphalt; 4 to 15 wt% of an additive; and the mass of the binding agent is 10-18% of the mass of the dry material. According to the light anhydrous stemming for the iron-making blast furnace, the volume density of the anhydrous stemming is reduced on the premise that the physical properties of the stemming are not obviously reduced, so that the consumption of the anhydrous stemming per unit iron amount is reduced. The invention further provides a preparation method of the light anhydrous stemming for the iron-making blast furnace.
本发明提供了一种轻质炼铁高炉用无水炮泥，包括：干料和结合剂；所述干料的成分包括：15～25wt％的轻质骨料；8～25wt％的矾土类骨料；5～10wt％的焦炭；10～20wt％的碳化硅；10～20wt％的氮化硅铁；3～10wt％的矾土类细粉；3～10wt％的白泥；2～6wt％的沥青；4～15wt％的添加剂；所述结合剂的质量为干料质量的10～18％。本发明提供的轻质炼铁高炉用无水炮泥在不明显降低炮泥物理性能的前提下，降低无水炮泥的体积密度，从而实现单位铁量无水炮泥消耗量的减少。本发明还提供了一种轻质炼铁高炉用无水炮泥的制备方法。
