Abstract: oxygen top high temperature is theconverter Metallurgical
Equipment, often in nearly 2000 degrees C temperature operation, it mustbe refractories wall built in the territory. Lining in extremely complicated, the intensity of physical chemistry response in refining process, it is not only bear high temperature and molten steel slag chemical erosion, but also to bear,molten steel gas furnace slag, soil erosion, and waste steel and machinery collisions. In the industrialized countries, the general refractories 60% to 70% is used in metallurgical industry, which for iron and steelindustry accounted for 65%to 75%. The development of the metallurgical industry has been talking about the new fire resisting materials and refractory material achievements and new technology for the metallurgical industry. We must not only understand steel and steel;
theconverter refractories nature of the factors affecting lining life,
aswell as in furnace is reasonable, and how to strengthen routine
maintenance should be clear.

摘要:氧气顶吹转炉是高温冶金设备，经常处于近2000°C的温度下作业，所以
内衬必须用耐火材料砌筑。炉衬在极其复杂，激烈的物理化学反应的冶炼过程中， 它不仅承受高温钢水与熔渣的化学侵蚀，还要承受钢水、熔渣、炉气的冲刷作用， 以及加废钢的机械冲撞等。在工业国家中，一般耐火材料的60%〜70%是用于 冶金工业，而其中用于钢铁工业约占65%〜75%。冶金工业的发展不断对耐火 材聊提出新的要求，而耐火材料的新成就又为冶金工业
