Production process of unfired alumina-magnesia carbon brick for electric furnace steel ladle
The invention relates to a production process of an unfired alumina-magnesia-carbon brick for an electric furnace steel ladle. The unfired alumina-magnesia-carbon brick for the electric furnace steel ladle comprises the following components: 20-40% of an alumina-magnesia-carbon reclaimed material, 30-60% of corundum, 3-10% of magnesium aluminate spinel, 7-14% of magnesia, 4-12% of crystalline flake graphite, 1-5% of activated alumina micro powder, 1-3% of metal aluminum powder and 2.3-2.8% of phenolic resin. The sum of all the components is 100%; the refractory material has the advantages of slag corrosion resistance, stripping resistance, corrosion balancing, good thermal shock resistance, long service life, no shrinkage, safety in use, less steel and slag adhesion, no pollution to molten steel, easiness in unpacking, convenience in customer construction and the like, and is a high-quality refractory material for ladle linings. By using the steel mill recycled reworked material, the resource consumption is reduced, and the production cost is reduced; high-temperature firing is not needed, and environmental pollution is reduced.
一种电炉钢包用不烧铝镁碳砖的生产工艺，所述的一种电炉钢包用不烧铝镁碳砖的组分为：铝镁碳再生料20％‑40％，刚玉30％‑60％，镁铝尖晶石3％‑10％，镁砂7％‑14％，鳞片石墨4％‑12％，活性氧化铝微粉1％‑5％，金属铝粉1％‑3％，酚醛树脂2.3％‑2.8％；以上各组分之和为百分之百；本发明具有抗渣侵蚀、抗剥落、均衡侵蚀、热震稳定性好、寿命长、不收缩、使用安全、沾钢沾渣少、不污染钢液、拆包容易客户施工便捷等优点，是一种优质的包衬用耐火材料。本发明使用钢厂回收再生料降低资源消耗，降低生产成本；无需高温烧成，减少环境污染。
