agglomerated raw materials. Briquetting was quickly replaced by the sintering technology developed by that time. High performance and manufacturability of the process, the possibility of utilization in it of the inevitable in the smelting of iron and steel dispersed iron-containing materials, led to its rapid spread.
Three types of iron input materials for both processes are liquid hot metal or in solidified form as pig iron, direct reduced iron (DRI) and hot briquetted iron (HBI) as well as steel scrap. Hot metal, pig iron, DRI and HBI are iron materials, which have to be produced from iron ore by the so-called ironmaking technologies.
The first HBI plant was started up in 1984 in Labuan Island, Malaysia by Antara Steel Mills to transport DRI safely. The now Wellspun-owned HyL Plant in Raigad, India was designed for HBI, but now ...
Overview. Hot Briquetted Iron (HBI) is a premium form of DRI that has been compacted at a temperature greater than 650° C at time of compaction and has a density greater than 5,000 kilograms per cubic metre (5,000 kg/m 3).. HBI was developed as a product in order to overcome the problems associated with shipping and handling of DRI - due to the …

In Part 1, we went back to the basics and described what is Hot Briquetted Iron (HBI), what makes it such a useful source of steelmaking metallics, how it became part of MIDREX® Direct Reduction Technology, and where HBI plants are located.Part 2 in the …
Announced in 2021, these iron ore briquettes began to be developed by us around 20 years ago at our Ferrous Metals Technology Center in Nova Lima, Minas Gerais. They are the latest in a long line of iron ore products we have offered over the course of our history, resulting from major investments in research and innovation.
DRI is produced in many forms. These are lump, pellets, hot briquetted iron (HBI), fines, and cold briquetted iron (CBI). HBI and CBI are densified forms of DRI to facilitate its handling and transport. HBI is …
Direct-reduced iron and its more transportable sister hot-briquetted iron have dallied in the wings of mainstream steelmaking as high-quality and low-residue furnace inputs for nearly 60 years. Suddenly the two have swept center stage for holding the key to steel decarbonization. ... which in addition to using Midrex technology, has …
At its heart is the HyIron technology, an innovative process to reduce iron ore in a rotary kiln with the help of green hydrogen, thus entirely carbon neutral. Every tonne of iron produced this way replaces 1.8 tonnes of CO 2 in the traditional process! At HyIron our aim is to implement and rapidly scale the production of green iron.
Abstract To substantiate the relationship between the quality of HBI and the material composition of pellets and the concentrate from which they were obtained, an array of data on the operation of the operating Hyl-3 metallization unit was used. The following are the main results of the work: (1) there is a pattern in the change in the quality of HBI …
Afterward, following pilot-scale and performing various laboratory studies, Cold-Briquetted Iron and Carbon (CBIC) was invented in Iran as a premium product over CBSI because of the prior's higher carbon content sand higher efficiency through processes of steelmaking (Patent No. IR84090).
The FASTMET Process converts steel mill wastes with or without the addition of iron ore fines into metallic iron in a rotary hearth furnace (RHF) using carbon as the reductant.
With an eye toward the future, Midrex Technologies and Primetals Technologies can produce high-quality HBI with the most environmentally friendly technology for ore …
The coal-based rotary kiln technology has become an increasingly mature ironmaking technology with iron-containing raw materials ... (DRI) or hot briquetted iron (HBI). The annual production is less than a hundred of million tons (86 Mt in 2017 [26]), but it is an attractive option to reduce CO 2 intensity with promising prospective [21]. More ...
ISO 15967 - direct reduced iron determination of - tumble and abrasion indices of hot briquetted iron (HBI). According to this standard, an abrasion drum with a diameter of 1,000 mm and a width of 500 mm with two lifters is used. Similar equipment is also used to test iron ore pellets and is illustrated in Figures 5 and 6 above. The
This process takes place at high temperature, approx. 750°C, with a very high briquetting pressure up to 180 kN/cmL. On the outlet of the press, the briquetted strips are conveyed to a separator consisting mainly of a …
The high productivity of the Midrex hot briquetted iron (HBI) plants in Russia was sustained by captive iron ore, low NG prices, and continuous demand for DRI. The DRI yields in Saudi Arabia and Mexico have grown relatively slowly, with outputs of 6.48 and 5.84 Mt in 2022, respectively.

In India there are many small rotary kiln furnaces producing DRI, known locally as sponge iron, using coal as energy and reductant source. Some of the sponge iron plants are captive to steel mills, but there is a significant domestic merchant market, India producing 57% of its crude steel in electric arc furnaces (2016).
This investigation was carried out to assess the behaviours of Cold Briquetted Iron (CBI) when exposed to increasing temperature changes up to its complete melting. High-temperature behaviours and melting characteristics of CBI were studied. Ground as-received CBI briquette and those heated to temperatures ranging from 500°C to 1000°C …
Hot Briquette Iron (HBI) Briquette iron is produced from direct reduced iron(DRI) in the process of producing briquettes and is widely used in most of steel plants worldwide. Briquetting process is categorized into two groups according to the temperature of the DRI entering briquetting machine, hot briquetting and cold briquetting.
