The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
WebSinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace. Sinter feed composition control is important because the various sinter feed ... WebJul 19, 2024 · Iron ore sintering is the second most energy-consuming process in iron marking, and the main energy consumption comes from the combustion of carbon (Hu et al. 2024 ). Coke breeze is intimately mixed with moistened ore fines, limestone/dolomite, and industrial wastes like flue dust, return fines, LD slag, LD sludge, etc.
WebThe reduction degradation behavior of iron ore sinter under different temperatures was studied by adapting kinetic reduction to simulate a blast furnace process, and the influence of coal gas composition on the reduction degradation examined. The results show that the reduction degradation process of sinter in blast furnace can be divided into ... WebMar 21, 2024 · The mixed ore powder sample was placed on top of the CaO sample and then placed into the sintering device to roast at 200°C in a specific heating system. The heating rate is 10° per minute until the end of the assimilation. Afterwards, the samples were naturally cooled and removed from the device.
