EFFECT OF BOF LINING EXPANSION JOINT ON CONTACT PRESSURE BETWEEN LINING AND SHELL

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.
