During the sintering process, iron ore fines are mixed with other additives such as fluxes, coke breeze, and return fines, and then heated in a sintering machine to form a solid mass known as sinter. The properties of the sinter depend primarily on the phase sequences formed during the sintering process. One of the important factors influencing the formation of phase sequences is the behavior of sulfur and iron, which play a crucial role in the physicochemical changes occurring during the sintering process. Therefore, it is necessary to study the behavior of sulfur and iron during the sintering process in order to improve the quality of sinter.Objectives:The objective of this study is to investigate the behavior of sulfur and iron during sintering process by using the serial sintering method. The specific objectives are:1. To determine the effects of sulfur and iron on the sintering process.2. To analyze the phase sequences formed during the sintering process in the presence of sulfur and iron.3. To investigate the influence of different sintering parameters, such as temperature, holding time and cooling rate, on the behavior of sulfur and iron.Methodology:The serial sintering method will be used for this study. The method involves the sintering of a small amount of material at a time, followed by the addition of more iron ore fines and additives for the next cycle of sintering. This process is repeated until a desired amount of material is sintered. The samples will be analyzed using X-ray diffraction (XRD) to identify the phase compositions and their evolution during the sintering process. The sulfur and iron contents of the samples will be measured by atomic absorption spectroscopy (AAS). 精品文档---下载后可任意编辑The sintering parameters, such as temperature, holding time and cooling rate, will be varied to investigate their influence on the behavior of sulfur and iron.Expected Outcome:Through this study, we expect to understand the behavior of sulfur and iron during the sintering process by using the serial sintering method. This study will provide valuable information on the effects of sulfur and iron on the phase sequences formed during sintering and help improve the quality of sinter. Additionally, the influence of different sintering parameters on the behavior of sulfur and iron will be analyzed, which can be used to optimize the sintering parameters for better quality sinter.
