Analysis of influencing factors and improving measures of permeability of sinter layer
Good air permeability is considered a critical guarantee for achieving sintering with thick layers and even ultra-high layers.Air permeability includes the original air permeability of the sintered layer and the thermal air permeability of the sintering process,which is affected by many factors.Based on the sintering research of limonite laterite nickel ore,factors affecting both the original and thermal air permeability of the sinter material layer across various stages such as raw material characteristics,batching,mixing,granulating,distributing,and sintering were analyzed.Improvement measures were also outlined.Furthermore,the research progress in sintering original air permeability and thermal permeability at domestic and international were summarized.The characteristics of various techniques for improving air permeability were also described in detail.Measures to improve sintering permeability,promote sintering homogenization,and improve sintering production quality are summarized,providing a theoretical basis for a deep understanding of the entire process of iron ore sintering,improving sintering permeability,enhancing the quality of sintered minerals,achieving green and high-quality development of sintering processes.
