Hot-briquetted iron (HBI) is a compacted form of DRI designed for ease of shipping, handling, and storage. Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore.
Natural gas is used to manufacture sponge iron and hot briquetted iron via the Midrex process [Wikidata]. Hot-briquetted iron (HBI) became a significant Libyan mineral export since the LISCO II plant began producing it in 1997. About 54% of Lisco's exports (by weight) in 2000 was HBI.

During 2020, 2019 and 2018, the company sold 12 million, 19 million and 21 million long tons of iron ore product, respectively, to third parties. [3] The company operates a Hot-Briquetted Iron (HBI) facility in Toledo, Ohio. HBI is a form of DRI that can be used as an alternative to scrap iron.
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
This plant processes iron ore pellets into iron using natural gas and water. The irons are then fed into electric arc furnaces in the slab steel plant and the billet steel plant. In these furnaces, the irons are mixed with scrap, hot briquetted iron, and other additional materials to produce two kinds of steels, namely slab steels and billet ...
Mill scale on an anvil. Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO, wüstite), iron(III) oxide (Fe 2 O 3, hematite), and iron(II,III) oxide (Fe 3 O 4, magnetite).
Wrought iron is a form of commercial iron containing less than 0.10% of carbon, less than 0.25% of impurities total of sulfur, phosphorus, silicon and manganese, and less than 2% slag by weight. [18] [19] Wrought iron is redshort or hot short if it contains sulfur in excess quantity. It has sufficient tenacity when cold, but cracks when bent or ...
