镁碳质耐火材料是70年代开发的新兴材料。由于它具有优异的耐火性能。良好的热稳定性。抗钢液与熔渣的侵蚀能力强,生产工艺简单,生产能耗低等一系列特点,所以很快的受到耐火、炼钢工作者们的重视,获得了日新月异的发展。一、武钢转炉炉衬发展历史的回顾武钢二炼钢的三座50t转炉所生产的钢种90％左右是碳含量在0.1％以下的低碳钢,其余10％左右为硅钢,钢水经吹氩调温或RH处理后进行连注,出钢温度高,渣中FeO数量大,冶炼条件十分苛刻。转炉自1977年
Magnesia carbonaceous refractories are new materials developed in the 70s. Because of its excellent fire resistance. Good thermal stability. Resistant to molten steel and slag strong erosion, the production process is simple, low energy consumption and a series of features, so quickly by fire-resistant, steel-making workers attention, access to rapid development. A review of the history of the development of converter lining of WISCO Wuhan Iron and steel production of the three 50t converter about 90% of the steel is less than 0.1% carbon content of low carbon steel, the remaining about 10% of silicon steel, molten steel by argon Even after the temperature or RH treatment, the tapping temperature is high, the FeO content in the slag is large, and the smelting conditions are very harsh. Converter since 1977
