摘要:介紹燒結機副原料(熔劑)破碎篩分系統技術的的改造,節省投資,利用資源,滿足生產而作的技改方案,并對技術上的可行性進行多種探討。 石灰石,白云石,蛇紋石及消石灰或生石灰等的來源,年供給量,運距及運輸方式。各項熔劑的平均化學成分,粒度,含水量。燒損及堆積密度。 熔劑是高爐冶煉過程中的造渣物質。按其性質可分為堿性熔劑、中性熔劑和酸性熔劑三類。由于我國鐵礦石的脈石成分絕大多數以SiO2為主,所以通常采用含有CaO和MgO的堿性熔劑。在燒結生產中加入熔劑,不僅可改善燒結過程,強化燒結,提高燒結礦質量、品質,而且可以向高爐提供自熔性和高堿度的燒結礦。熔劑與礦石中的高熔點脈石能生成熔化溫度較低的易熔體;能造成一定數量和一定物理化學性能的爐渣,達到去除有害雜質的目的(如去硫)。 關鍵詞:破碎篩分 堆積密度 堿性熔劑
ABSTRACT:The sintering machine auxiliary material (flux) transformation of crushing, screening system technology can save the investment, utilization of resources, technical solutions to meet production and made, and the feasibility of the technique on various study. Limestone, dolomite, source of serpentine and lime or lime, year of supply, transport distance and transport. The average chemical composition, the flux of particle size, moisture content. Burning and bulk density. Flux is slagging material of blast furnace smelting process. By their nature can be divided into alkaline, neutral and acidic flux flux flux three. The gangue of iron ore in China the most mainly to SiO2, so we usually use basic flux containing CaO and MgO. Adding flux in sintering production, not only can improve the sintering process, sintering, improve sinter quality, quality, but also to provide self-fluxing sinter blast furnace and high alkalinity. High melting point and gangue flux in the ore can generate lower melting temperature is easy to melt; the slag can cause a certain amount and some physical and chemical properties, to remove harmful impurities (such as the purpose of desulphurization). Keywords: crushing and screening; Packing density; basic flux
