TECHNICAL FIELD
[0001] The present application relates to the technical field of sintering, in particular to a sintering device. BACKGROUND
[0002] At present, according to the relevant research results published by China Iron and Steel Industry Association, the long process ironmaking process is still the main iron front process of the steel industry in the next 10 years, and the artificial lumping process of the furnace charge-sintering method still accounts for more than 50% share and is still an important iron front furnace charge product. The sintering method lumping process mainly includes ore blending, mixing, granulation, sintering, cooling, and particle sizing processes. In recent years, the sintered ore powder is deteriorated by the superimposed ore powder grade, and a large amount of limonite and fine particle hematite is used for sintering and eating, which increases the difficulty of the mixing process and reduces the granulation quality index, and thus causes the process index of the sintering process to deteriorate and causes the problem of material sticking in the ore bin.
