How is hot briquetted iron 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.
Is hot briquetted iron flammable?
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 cold briquetted iron?
Cold Briquetted Iron and Carbon (CBIC) In other words, CBIC is a metallic material molded in briquette shape, derived from a compressing process through which pellet DRI is fed into the roller presses at room temperature.
What is sponge iron used for?
Sponge iron is used in the iron and steel industry as a substitute for scrap in induction and electrical arc furnaces. Over the years, the shortage of expensive melting scrap has made sponge iron a significant raw material for manufacturing high quality steel.
What is difference between pig iron and sponge iron?
The key difference between sponge iron and pig iron is that we can produce sponge iron by direct reduction of iron ore through reducing agents whereas the production of pig iron is by melting iron ore with charcoal and limestone at very high pressures.
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.
Which is the closest to the purest form of the iron?
Wrought iron is the purest form of iron. It contains 0.12 to 0.25\% carbon and is thus the purest form of iron.
