【Abstract】 In order to study the performances of the new No.1 blast furnace(BF) of Baotou Steel Group under accidental conditions,an elastic analysis has been carried out at first.Based on the elastic finite element results,a further elastoplastic analysis of the whole structure has been made to study the stress concentrations.The stress patterns,the appearances and developing processes of the local plastic zones have been obtained,which can provide a scientific basis for the design and construction of the BF.更多还原
