The HBI direct reduction process - voestalpine

03-11-2016· HBI stands for hot briquetted iron – porous sponge iron, pressed into briquettes. HBI is created by reducing the iron ore with natural gas. HBI can be used as a pre-material in blast furnaces or electric arc furnaces. In blast furnaces, HBI replacesSponge iron (DRI, HBI) briquette making and the,,16-03-2020· Direct Reduction is a metallurgical process of producing sponge iron from iron oxides (mainly from lump iron ores or pellets) directly in the solid phase. The product of this solid state route has a honey comb structure with minute pores. Hence this product is most commonly known as sponge iron/direct reduced iron (DRI).No. 11.7 HBI – Hot Briquetting of Direct Reduced Iron,,During direct reduction, oxygen is removed from iron ore in solid state. This procedure results in a spongy structure of the product, thus "Sponge Iron", with a high porosity. De- pending on the raw material and the reduction process applied, apparent product density is approx. 2 g/cm³ associated with a very high specific surface area.
