Study on the Influence of Materials on Heat Transfer Characteristics of Blast Furnace Cooling Staves

摘要

Cooling stave is one of the most important equipment of blast furnace for iron making. The heat transfer performance and service life of the cooling stave, to a large extent, determines the efficiency and economy of the iron making process. In this paper, a 3-D heat transfer model of cooling stave was founded by ANSYS based on FEM theory, and the heat transfer characteristics of cooling staves which were made of different materials (cast iron, cast steel and copper) were analyzed. Then, several suggestions on choosing material of cooling staves were given according to the calculation results and the actual working conditions of the cooling staves.
