Abstract：The bell-less top charging system is widely used for the blast furnace in ironmaking industry .As a critical component of the bell-less top charging system , the central throat has long been under the effection of impact abrasion and high temperature erosion .Firstly, the 3D model of the central throat was established , and the static mechanical analysis was performed by using the finite element software .Secondly , the static mechani-cal analysis results employed as the boundary conditions , the thermal-structural coupling analysis of the central throat was carried out .The analysis result illustrates that there is stress concentration around the corner of the upper part of the central throat .After structural improvements , the thermal stress is effectively reduced , and the impact abrasion and high temperature erosion of the central throat were declined too .
