The study of cooling channel optimization in blast furnace cast steel stave based on heat transfer analysis

摘要

The three-dimensional heat transfer and thermal stress of a steel cooling stave in a blast furnace at Maanshan Iron and Steel Co. Ltd. are built. The temperature and thermal stress fields of cooling stave are calculated by using finite element method software ANSYS. The results show the rise in maximum temperature and thermal stress of the stave hot surface is not high when cooling pipe is replaced by cooling elliptical tube. Because of the decrease in the cross-sectional area for cooling elliptical tube, the thickness of the cooling stave is reduced and cooling water flow is saved. As a result, the iron-making cost can be reduced.
