What is HBI cargo?
Hot Briquetted-Red Iron (HBI) is a material derived from a densification process whereby the direct reduced iron (DRI) feed material is subjected to a hot moulding process by which briquettes of iron are formed under pressure at a temperature greater than 650C at time of moulding and has a density greater than 5.0gms/ …
What is HBI fines?
During the production, transportation and storage of HBI, large quantities of small particles or dust are produced; these are known as fines. HBI fines, therefore, can be as dangerous as DRI and perhaps should actually be called DRI.
Is hot briquetted iron flammable?
During oxidation, HBI absorbs oxygen, making the air in the HBI storage facilities potentially dangerous for people. HBI can ignite when exposed to open flame, drops of molten metal, in contact with heated materials and flammable substances, as well as when moistened with sea water.
What is HBI steel?
Hot Briquetted Iron (HBI) is a relatively new product, developed in the past 25 years, as a supplement for pig iron and scrap in electric furnace steel mills. It is a compacted form of direct reduced iron (DRI), which facilitates its handling, storage, and use.
What is the difference between DRI and HBI?
Direct reduced iron (DRI) is produced by the direct reduction of iron ore in the solid state. Hot briquetted iron (HBI )is DRI that has been briquetted under very high pressure and at elevated temperature to form dense briquettes that are much less porous than DRI and therefore much less reactive.
What is HBI steel used for?
HBI (Hot Briquetted Iron) can be used as a scrap supplement in Electric Arc Furnaces allowing the production of most demanding steel grades. HBI is also used in Blast Furnaces to boost productivity and to reduce the coke consumption or in Blast Oxygen Furnaces as a low-residual substitute for scrap.
What does HBI stand for?
HBI
| Acronym | Definition |
|---|---|
| HBI | Historically Black Institution |
| HBI | Host Bus Interface (computing) |
| HBI | Health and Biomedical Information |
| HBI | Hot Beef Injection (band) |
Where is HBI used?
HBI is used primarily in the electric arc furnace (EAF) for its diluent effect; i.e., to lower the overall level of metallic residuals and sulfur.
How is HBI produced?
HBI is the product of reducing iron ore with natural gas. HBI stands for hot briquetted iron – porous sponge iron, pressed into briquettes. HBI is created by reducing the iron ore with natural gas. In blast furnaces, HBI replaces coke and iron ore, while in electric arc furnaces it replaces scrap metal.
How do you make HBI?
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 replaces coke and iron ore, while in electric arc furnaces it replaces scrap metal.
What does HBI stand for in construction?
HBI—Hot Briquetted Iron. HBI stands for Hot Briquetted Iron. This is porous sponge iron pressed into briquettes.
How is HBI classified as a hazardous cargo?
Shipping and handling. HBI – Direct Reduced Iron (A) – is classified as Group B (cargo with chemical hazard) and class MHB (material hazardous only in bulk) under the International Maritime Organisation’s International Maritime Solid Bulk Cargoes Code, but, unlike DRI which requires shipment under an inert atmosphere,…
What’s the difference between HBI and DRI briquettes?
The DRI must remain dry all the time before the carriage and during the voyage. HBI is produced from DRI, which is compacted at the temperature above 650° C to form the briquettes between around 90 mm to 130 mm long, 80 mm to 100mm wide and 20 mm to 50 mm thick.
Is the CBI to be shipped to DRI?
It is definitely of significance to know the original source of material which is used to produce CBI– in case this cannot be verified, then the CBI shall be handled and shipped in the same manner to DRI.
