摘要
耐火材料损坏除了化学侵蚀以外 ,还有热机械应力。前者是指熔体、气体、灰尘对耐火材料的化学侵蚀及冲刷等 ,后者是指由于温度及某些内在的化学反应引起的膨胀及机械负荷在耐火材料内部产生的应力 ,超过其强度极限而导致耐火材料损坏 ,而热机械应力的计算主要用有限元法。
Thermal and mechanical stress besides chemical corrosion is the main wear mechanism of refractories.Chemical corrosion is caused by erosion and chemical reactions with flux,gas,dust etc.Thermal and mechanical stress results from expansion that is caused by temperature and chemical reaction and mechanical load.Finite Element Method (FEM) is an effective way for calculation of thermal and mechanical stress.In this paper,FEM and its application in refractories are reviewed,the development and outlook,matters which should be paid attention to of FEM's application in refractories are discussed.
