The running quality of converter especially 100t～500t medium and large converter refers to the safety indicators such as no obvious wear,impact,vibration and abnormal noise,and the stable operation of the equipment with sufficient safety margin and stability,etc.In this paper,six typical under suspension support mechanisms which mainly used in various countries in the world today are described,and the characteristics of the suspension support mechanism under the converter are analyzed from three aspects:components,number of suspension support mechanism and layout of suspension support mechanism.The stress and deformation of the supporting mechanism are analyzed by finite element method and verified by a large number of practical engineering.The research results show that the connecting rod mechanism is the best choice for the hanging mechanism of converter.The optimal combination of the number of hanging mechanisms is to adopt four groups of vertical hanging mechanisms and four groups of horizontal supporting mechanisms;the optimal position of the hanging mechanism is that the horizontal support mechanism is located directly above the vertical hanging mechanism.The running quality of the converter must be excellent if all three of the above are met,which also means the trend and direction of the development of the support technology of the converter in the future.
