EFFECT OF BOF LINING EXPANSION JOINT ON CONTACT PRESSURE BETWEEN LINING AND SHELL
-
摘要: 转炉炉衬砌筑时设置的膨胀间隙不同会导致炉衬与炉壳之间的接触压力不同,进而导致炉衬的热应力不同。由于结构上的原因,炉衬与炉壳之间的接触压力很难用实测的方法得到。为得到炉衬与炉壳之间的接触压力,应用有限元软件,对炉体工作过程进行模拟、仿真,得到的炉衬与炉壳之间接触压力结果可为进一步分析砌炉是否合理、求解炉衬的热应力奠定必要的基础。Abstract: The different expansion joint set in lining-up BOF will lead the different of contact pressure between lining and shell,and further produce different thermal-stress.Thanks to structural cause,measuring the contact pressure of lining and shell is relatively difficulty.with the help of FEM(finite element method),working process of BOF can be simulated and the contact pressure of lining and shell can be obtained through numerical simulation.The result is a necessary preparation for further analysis the reasonableness of lining masonry and the thermal-stress of lining.
