| 摘 要： | 用镁质干式打结耐火材料代替成型镁砖作为铁合金精炼电炉的炉衬材料在中国已得到普遍应用。本文介绍了此种材料的发展过程，叙述了打结料的化学成分、物理性能及使用特点。由于这种打结料MgO含量高、烧结性能好，因而制成的电炉炉底耐火性能强、整体性能好、热震稳定性能好。通过对打结料烧结过程中矿物组成的变化及使用后的电炉炉底的解剖分析，揭示了炉底长寿的原因。在精炼电炉上普遍获得了明显效益。

| Abstract: | Magnesia ramming materials have been widely used in China instead of magnesia bricks as furnace lining materials of ferroalloy refining furnace. The paper introduces the development of the ramming material, recounts its chemical composition, physical property and application characteristics. Because of its high MgO contents and fine sintering property, the ramming furnace bottom has the properties of good refractory, monolithic construction and thermal shock resistance. The changes in mineral compositon and furnace tearout characterization show the reasons for the bottom's long service life. The obvious benefits are widely achieved, the annual saving cost in refractory is about 2 millions US dollars. |
