Abstract

In order to improve the accuracy of calculation for erosion of lining of blast furnace hearth and shorten the calculation time, quasi- 3D dimensional method was used for calculation of erosion for shaft section of lining of blast furnace hearth. The calculation used the correction item of circumferential heat transfer to replace circumferential heat transfer and gave the treatment method for correction item of circumferential heat transfer. The erosion model for axial section of lining of hearth was established by using ANSYS software. The successive approximation method was adopted to modify the boundary of erosion, then the steady- state calculation was done. The calculation steps of quasi three dimensional method was described. The difference between the models established by 2D method and quasi- 3D method was analyzed by actual example. The simulation results show that quasi- three- dimensional method has a smaller amount of calculation but higher accuracy than two- dimensional method, which verifies that quasi- three- dimensional method is suitable to analysis of erosion.
