众所周知,为了使脉石熔化,并使之在炉渣熔体中流动,以保证炉况顺行并得到合格的生铁质量,必须在高炉内添加熔剂。除了采用未经处理的石灰石矿外,在原料加工时,将铁矿石预先加工成自熔性炉料是添加熔剂最经济最合理的方法。这不仅使冶炼指标,而且使生铁质量都将因烧结矿的助熔而得到明显改善。 It is well-known that fluxes must be added to the blast furnace in order to melt the gangue and allow it to flow in the slag melt to keep the furnace running smoothly and to obtain acceptable pig iron quality. In addition to the use of untreated limestone mines, the pre-processing of iron ore into self-fusing charge materials is the most economical and rational way to add flux during raw material processing. This not only makes smelting targets, but also the quality of pig iron will be significantly improved due to sintering flux.
