本文利用半解析有限元法对宝钢１号高炉进行了静力及动力强度分析，并利用有限元二次分析法对风口区进行了应力集中分析，从而为设计高炉和延长炉壳使用寿命提供了科学依据。
In this paper, semi-analytical finite element method of Baosteel No. 1 blast furnace carried out static and dynamic strength analysis, and the use of finite element analysis of the tuyere area stress concentration analysis, so as to design the blast furnace and extend the life of the furnace shell provided Scientific basis.
