Repairing material for molten iron pretreatment desulfurization spray gun cracks
The repairing material is prepared from the following raw materials in percentage by weight: 71 to 82 percent of 85 to 88 alumina, 4 to 9 percent of activated aluminum oxide micro powder, 1 to 3 percent of silicon dioxide micro powder, 3 to 7 percent of fraxinus mandshurica clay, 0.5 to 1.5 percent of chrome green, 1.5 to 6 percent of chromium concentrate, 0.3 to 1.5 percent of boric acid, 3 to 6 percent of PA80, 0.1 to 0.3 percent of CMC, 0.05 to 0.15 percent of organic chemical fiber and 0.03 to 0.1 percent of iron concentrate powder. The raw materials are uniformly mixed in proportion, and the prepared repairing material has good air permeability, adhesion performance and rapid sintering performance before pug sintering, so that the thermal state stability is guaranteed, the binding force is high, and the repairing material has high anti-stripping performance and extrusion rheological property.
本发明公开了用于铁水预处理脱硫喷枪裂纹的修补料，由以下重量百分比的原料组成：85‑88矾土71‑82％、活性氧化铝微粉4‑9％、二氧化硅微粉1‑3％、水曲柳黏土3‑7％、铬绿0.5‑1.5％、铬精矿1.5‑6％、硼酸0.3‑1.5％、PA803‑6％、CMC 0.1‑0.3％、有机化纤0.05‑0.15％、铁精矿粉0.03‑0.1％。本发明中将各原料按比例混配均匀，制得的修补料具有良好的泥料烧结前的透气性和附着性能，快速烧结性能，从而保证热态稳定性能，结合力强，具有较强的抗剥落性能和挤压流变性。
