除化学侵蚀之外,RH脱气装置耐火衬的温度分布和应力是影响耐火衬寿命的重要因素。 以钢结构和航空领域广泛应用的有限元分析法,通过最新的计算机程序模拟了陶瓷材料的各种主要性能(如应力—应变特性)与温度的关系。在RH脱气装置中,耐火砖衬的应力—应变特性也与耐火砖衬的接缝有关。 Yeitscher Magnesitwerke公司为确定250t RH脱气装置在处理过程中的温度场,对三种不同处理
In addition to chemical attack, the temperature distribution and stress of the refractory lining of the RH degasser are important factors that affect the life of the refractory lining. Based on the finite element analysis (FEM) method widely used in steel structure and aeronautics field, the relationship between temperature and various main properties (such as stress-strain characteristics) of ceramic materials has been simulated by the latest computer program. In the RH degasser, the stress-strain behavior of the refractory lining is also related to the seam of the refractory lining. Yeitscher Magnesitwerke company to determine 250t RH degassing device in the process of temperature field, three different treatments
