Abstract Abstract II II Abstract At present, along with the rapid development of Chinas iron and steel industry, the demand for sintering equipment is growing, and the sintering machine, as one of the devices which supply blast furnace raw material, also plays more and more important role. Sintering machine trolley is mainly responsible for charging, ignition, sintering on the track and discharging sinter trolley at the rear end, so its operation will directly affect the quality of sinter. This study introduced the Lu Qi belt sintering machine tail trolley arching phenomenon, and made certain improvement design for the key parts so as to reduce the arch by taking 450 m2 of band sintering machine for example. In order to fundamentally solve the problem of lower level track arch, this paper further analyzed the causes of arch from the viewpoint of mechanics, put forward power control threshold, and verified the correctness of the formula of threshold through the virtual prototype simulation. At the same time, a series of band sintering machine force value database were established, which provided theoretical reference for later similar belt sintering machine designed. At first, this study calculated the basic parameters of the belt type sintering machine, mainly including effective sintering area, the trolley running speed, and center distance, quantity of trolley etc. Then from the work principle of the trolley at tail of sintering machine, it introduced some key structural design and analysis of belt sintering machine, including car body structure design, the tail wheel design and analysis, trolley wheel rail design and so on, to effectively ensure the normal operation of the sintering machine tail trolley and reduce the arch. Secondly, in order to fundamentally solve the problem that the belt sintering machine arches, under the basis of structure design at the previous chapter, this study established the tail trolley plane mechanical arch model by taking 450 m2
