"镶嵌式烧结工艺：应对铁矿石变化的新技术探索"

The embedded sintering process is a new technology developed in response to the increasing global steel production, which has led to the depletion of high-grade iron ore and an increase in the use of other types of iron ores such as hematite, goethite, and pisolitic ores. This trend is particularly evident in countries like Japan, where the proportion of coarse pisolitic ores has increased significantly. The change in the properties of iron ores not only affects the production and quality of sintering but also influences the metallurgical characteristics of the ores in the blast furnace. Therefore, there is a need to further develop sintering technologies and processes, including methods for pre-treating raw materials. In 2005, the Japan Iron and Steel Institute (ISIJ) initiated a research project titled "New Sintering Process through Designing of Composite Granulation" in collaboration with several steel companies and universities. This project aims to explore innovative ways to enhance the sintering process by designing a composite granulation bed structure. The embedded sintering process offers a promising solution to the challenges posed by the changing nature of iron ore resources. By optimizing the granulation process, it enables better control over the sintering parameters, resulting in improved sinter quality and metallurgical performance in the blast furnace. Overall, the embedded sintering process represents a significant advancement in sintering technology, with the potential to revolutionize the iron and steel industry by addressing the issues of raw material availability and quality, ultimately contributing to more sustainable and efficient steel production processes.
