Converter lining gunning mix with strong adhesive force
The invention provides a converter lining gunning mix with strong adhesive force, and relates to the technical field of converter steelmaking. The converter lining gunning mix with strong adhesive force is prepared from the following raw materials in parts by weight: 30 to 50 parts of high-purity magnesite clinker particles, 25 to 35 parts of fused magnesite particles, 20 to 40 parts of fused magnesite fine powder, 10.5 to 29.5 parts of binding agent and 1 to 3 parts of diesel oil, the binding agent is prepared from the following raw materials in parts by weight: 1 to 5 parts of medium-temperature modified asphalt, 1 to 5 parts of powdery phenolic resin, 1 to 5 parts of phosphate, 2 to 5 parts of saltpeter ash powder, 2 to 4 parts of a-Al 2O3 powder, 0.5 to 1.5 parts of sintering aid and 3 to 5 parts of flow aid. By introducing the diesel oil, the gunning material avoids the use of water, the problem that external moisture corrodes a lining of a converter is avoided, the problem that water enters the converter to damage the atmosphere in the converter is avoided, the hidden dangers in multiple aspects such as safety and breakout caused by water entering the converter are avoided, meanwhile, the interior of the gunning material is fully sintered under the action of high temperature, and the service life of the gunning material is prolonged. And the sintering efficiency is improved.
本发明提供一种附着力强的转炉内衬喷补料，涉及转炉炼钢技术领域。该一种附着力强的转炉内衬喷补料，包括以下重量份的原料：高纯烧结镁砂颗粒30‑50份、电熔镁砂颗粒25‑35份、电熔镁砂细粉20‑40份、结合剂10.5‑29.5份、柴油1‑3份，所述结合剂包括以下重量份的原料：中温改质沥青1‑5份、粉状酚醛树脂1‑5份、磷酸盐1‑5份、硝石灰粉2‑5份、a‑A l 2O3粉2‑4份、助烧结剂0.5‑1.5份、助流剂3‑5份。通过柴油的引入，使喷补料避免了水的使用，避免了外来水分对转炉内衬腐蚀的问题，避免了水进入转炉内破坏炉内气氛的问题，避免了水进入转炉内而导致安全及漏钢等多方面的隐患，同时在高温的作用下使得喷补料内部充分烧结，提高了烧结效率。
