Sponge iron is formed through the reduction of iron ore to metallic iron through reaction with carbon in the form of coal, etc. at approx. 1100 degree Celsius. Sponge iron is also referred to as direct reduced iron, metalized iron, or hot briquetted iron.
DRI – Direct reduced iron. Normally in the form of sponge pellets or lumps varying between 6 and 25mm nominal diameter, but often 8 to 12mm diameter. The IMO BC Code classes this product as "a material that is hazardous only when in bulk" (MHB). It can be found under the BC Code as BC015.
HBI stands for Hot Briquetted Iron and is sponge iron in briquet form (several sponge iron pellets pressed together into a larger lump). Sponge iron in the form of DRI and HBI The traditional way of producing steel involves removing oxygen from the iron ore using carbon and coke in a blast furnace, in what is known as a reduction process.
Hot briquetting iron (HBI) is a top quality raw material for the manufacture of steel which contains more than 90% total iron (Fe) in almost pure form and is used in the blast furnace (BF,BOF) and electric arc furnace (EAF). High thermal and electrical conductivity of …
The process is flexible to produce three different product forms, depending on the specific requirements of each user. The three forms of DRI are cold DRI, HBI or hot DRI ('Hytemp' iron). Cold DRI discharge is normally used in an adjacent steel melt shop close to the direct reduction plant.
Hot Briquetted Iron (HBI) is the densified briquette form of Direct Reduced Iron (DRI). DRI is discharged hot from the reduction furnace and screwfed into the nip between - two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures (at least 650°C [1202°F]) and high

DR process, DRI, HBI, Iron making. Metallization, reformed natural gas, residual elements, Rotary kiln, Direct Reduced Iron and its Production Processes. Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas.
In FY-20, India's steel production was 109 MT, and it is the second-largest steel producer on the planet, after China. India's per capita consumption of steel was around 75 kg
Iron flakes are likely to burn because they are flammable. Unlike scrap iron, which is almost pure hot briquetted iron, sponge iron has silicon impurities that must be separated during the manufacturing process. Global analysis of hot briquetted iron . Its production …
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.
Sponge iron when briquetted in hot condition at elevated temperature is called hot briquette iron (HBI). Sponge Iron Technology in India and abroad. In India, a modest beginning in the field of sponge iron making was only be made in mid 80's by setting up the country's first coal based demonstration-cum-production unit of 30,000 TPA (Tonnes ...
The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with
The latest reported figures for Iran's sponge iron production, reported by the World Steel World Association, are about 2.395 million tonnes, showing an average monthly growth of + 7.6% for the month of April 2019. The average increase in production in the first five months of 2019 is estimated at + 17.7%. Sponge iron process
The reactor produces direct reduced iron (DRI), also called sponge iron, which is a porous, solid iron with low carbon content (below that of pig iron from a blast furnace). It can then be either compacted into hot briquetted iron (HBI, a briquette of DRI compacted at 650℃ to at least 5000kg/cubic meter to facilitate storage and transport) or ...
The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed.
