direct reduced iron dust collection

Microwave

2020/2/15The direct reduced iron was obtained by magnetic separation of reduced briquettes. Abstract This study applied microwave energy for rapid self-reduction of electric arc furnace (EAF) dust-biochar composite briquettes to produce powdered direct reduced iron (DRI), based on the good electromagnetic response of EAF dust-biochar composite briquettes.

Iron Ore Smelting Process

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being Get price

Analysis of Reducing Characteristics of Direct Reduced Iron

2016/7/31In general, direct reduced iron is reduced and manufactured from iron ores in solid state, where coal or carbon monoxide is used as a reducing agent (see Fig. 1). Stepwise reduction reaction of iron oxide proceeds in the order of Fe 2 O 3 (hematite, HCP) → Fe 3 O 4 (magnetite, cubic) → FeO (wustite, cubic) → Fe (metallic iron, BCC or FCC), and may be represented as shown by the following Get price
