China is the world's largest steel producer, with Iron and Steel Association estimating that country's crude production in 2022 will be 935 million tonnes [Citation1]. In 2017, metallurgical slag output of iron enterprises reached more than 440 tons, including 247 tons blast furnace 101 converter [Citation2]. After accumulation recent years, current number waste huge. By 2020, total amount indu...

In this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. For this reason, various experimental parameters such as pH, contact time and the primary ion concentration were investigated. The remaining concentrations of ions such as; Mn2+ and Fe2+ in water were measured by atomic adsorption spectroscopy. The chemical and p...

The life of the hearth is main limiting link campaign a blast furnace. As equipment for holding molten iron in furnace, high-temperature direct contact with refractory, which makes refractory have larger temperature increase. If gradient inside large, it generates large thermal stress and causes to crack. Blast furnace gas intrude into gap, directly melting erosion other chemical carbon bricks....

The associated mineral ore accompanying Valuable Metal Compounds (VMC) have been usually treated in a smelting furnace ,such as Blast Furnace, Reverberatory, Blowing Furnace, hence the VMC were mostly concentrated into the molten associated slags and separated from liquid metals. So the associated slags become an important man-made resources (Table I), in which the VMC exist dispersively in var...
