Converter repairing material prepared from recycled pleonaste bricks
The invention discloses a converter repairing material prepared from recycled pleonaste bricks. The converter repairing material comprises the following raw materials in parts by weight: 20-40 parts of fused magnesia particles, 25-45 parts of waste pleonaste brick particles, 12-22 parts of fused magnesium powder, 6-12 parts of modified asphalt, 2-8 parts of phenolic resin, 2-8 parts of combustionpromoter and 1-5 parts of an additive and a wetting agent, wherein a mass ratio of the additive to the wetting agent is (3-4): (2-2). Compared with a repairing material in the prior art, the repairingmaterial has the advantage that the recycled pleonaste bricks are processed into particles with different particle sizes for use. By adding the wetting agent, the wrapping effect of the particles anda binding agent can be improved, and dust pollution generated during manufacturing and stirring can be effectively reduced. The asphalt-resin composite bonded repairing material prepared by adoptingthe above scheme has the advantages that sintering time is shorter (generally about 40-50 minutes), the technical problem of recycling of waste refractory materials is solved, and cost is reduced.
本发明公开了一种利用回收镁铁尖晶石砖制备的转炉修补料，一种利用回收镁铁尖晶石砖制备的转炉修补料，它包括以下重量份的原料：电熔镁砂颗粒20‑40份、废镁铁尖晶石砖颗粒25‑45份，电熔镁粉12‑22份，改性沥青6‑12份，酚醛树脂2‑8份，促烧剂2‑8份，添加剂及润湿剂1‑5份；所述添加剂与润湿剂的质量配比为3‑4:1‑2。本发明与现有技术的修补料相比，采用回收废镁铁尖晶石砖加工处理成不同粒度颗粒使用。通过加入润湿剂可以增加颗粒与结合剂的包裹效果，并具可有效减少制作搅拌时产生的粉尘污染。采用此种方案制备的沥青和树脂复合结合修补料，烧结时间较短(烧结时间一般为40‑50min左右)，解决了废旧耐火材料回收再利用的技术问题，降低了成本。
