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.

For example, ore used in the direct-reduction process to make direct-reduced iron (DRI) or hot-briquetted iron (HBI) destined for melting in an electric-arc furnace (EAF) needs to be of much higher grade than that fed into a blast furnace. Prices vary accordingly. Dynamic markets

Austeel Pty Ltd proposes to mine iron ore from the George Palmer Orebody on a pastoral lease about 25km south of Cape Preston. Ore will be fed to a purpose-built process plant to produce up to 13.8 million tonnes per annum of pellet iron and 4.7 million tonnes per annum of direct reduced iron (DRI) and/or hot briquetted iron (HBI).

The direct reduction process: Hot reducing gas flows through the iron ore, from the bottom to the top, according to the counterflow principle The Oxygen content is reduced = "sponge iron" is produced "Sponge iron" is pressed into briquettes (Hot …

DRI, being one of those substitutes in addition to pig iron and hot briquetted iron (HBI), is thus set for accelerating demand in near term. As more number of steel making companies prioritize countervailing thinning prime scrap supplies at domestic levels, FMI's analysis projects an optimistic growth outlook for the direct reduced iron market.

The interim technology relies on the direct reduction (DR) process where natural gas is used to produce direct reduced iron (DRI) in the densified form of hot briquetted iron (HBI). With respect to the core process of DR, this results in a CO 2 reduction of 50% when compared to the BF process. Depending on the generation capacity for power used ...

The use of direct-reduced iron (DRI) and hot-briquetted iron (HBI) production technologies, much like ten years ago, is considered one of the most promising …

Hot briquetted iron (or HBI) is direct reduced iron that has been briquetted under very high pressure and at an elevated temperature to form dense briquettes that are much less porous than DRI and therefore much less reactive to the atmosphere. Oxidisation of DRI generates heat, which in bulk cargoes of DRI can be significant and represent a ...

Direct Reduced Iron Technology Committee MISSION: To focus on the emerging market and technological trends for the production, handling, and use of direct reduced iron (DRI) and hot briquetted iron (HBI) products as well as present and future alternative iron production technology.

energy and quality of fuel is the Direct Reduction of Iron (DRI), which accounts for ~75 Mt/y of iron. The yielded spongy iron is further processed by sintering to obtain more compact and easily transportable Hot Briquetted Iron (HBI), which is afterwards molten by e.g., arc furnaces to obtain steel alloys. To control the quality of starting iron

Hot water outlet pipe. If sediment builds up in your tank to the point of plugging up both of these pipes, you'll see a drastic reduction in your hot water pressure. Because Florida's water is very "hard" (has a high mineral content), sediment build-up in water heaters is just one of the many common problems here caused by hard water.

Wi-Fi Direct (formerly Wi-Fi Peer-to-Peer) is a Wi-Fi standard for peer-to-peer wireless connections that allows two devices to establish a direct Wi-Fi connection without an intermediary wireless access point, router, or Internet connection. Wi-Fi Direct is single-hop communication, rather than multihop communication like wireless ad hoc networks.. Wi-Fi becomes a way of communicating ...

Hot Direct Reduced Iron (HDRI) is iron not cooled before discharge from the reduction furnace, immediately transported to a waiting electric arc furnace and charged thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which uses (requires) sized iron ore ...

33 direct reduction modules operating in Iran and at least a dozen more were in various phases of construction. DRI capacity growth has been phenomenal – three-and-one-half times more capacity now than one decade earlier – especially considering the international sanctions placed on the country.

The International Maritime Organization (IMO) describes direct reduced iron as DRI (A) Hot-moulded briquettes, DRI (B) Lumps, pellets, and cold-moulded briquettes, and DRI (C) By-product fines. 1.6. Direct Reduced Iron (A) or DRI (A) Briquettes, hot-moulded IMO classification for Hot Briquetted Iron (HBI) – see Definition 1.11. 1

The direct reduction processes in combination with the melting of directly reduced iron to produce steel in the EAF offer an alternative to the BF-BOF route. The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a …

Hot Direct Reduced Iron (HDRI) is a direct reducing iron that is transferred hot and directly from the reduction furnace into the arc furnace, resulting in energy savings. The direct reduction process uses pelleted iron ore or natural "lump" ore. An exception is the fluidized bed process, which requires inorganic iron ore particles.

Analyzing Direct Reduced Iron and Hot Briquetted Iron Using XRD. Steel is one of the most widely used materials in society, and global rates of steel production continue to grow. Growing demand has caused production rates to reach ~1,550 Mt/y. The majority of raw iron is made using blast furnaces and necessitates the implementation of high ...

'Direct reduction' refers to processes which reduce iron oxides to metallic iron below the melting point of iron. The product of such solid state processes are called direct reduced iron (DRI), whereas the product of the blast furnace is referred to as hot metal in the molten state, or pig iron in the solidified form.

This forms the direct reduced iron (DRI) which is typically composed of 90 to 94% iron. After the DRI exits the shaft furnace, it can be cooled and compressed to briquetted iron for safe storage and transportation. The hot metal can also be taken directly to …

NIPPON STEEL ENGINEERING CO., LTD. provides new iron source technology that enables the achievement of productivity improvements, operational cost reductions, CO 2 emissions reductions, and capital investment reductions through the optimal combination of Tenova HYL and Danieli's natural gas-based direct-reduced iron technology (ENERGIRON) with our blast furnace equipment technology …

Hot briquetting is a reliable, fully developed industrial concept for the passivation of direct reduced iron produced with the various processes of direct reduction. Because, during hot briquetting, the large specific surface area of direct reduced iron is drastically reduced, the well known problems caused by reoxidation, overheating are avoided.

Direct Reduced Iron. Direct reduced iron (DRI) is also known as sponge iron. It is produced by the reduction of iron ore (in the form of lumps or pellets) by either non-coking coal or a reducing gas produced by reforming of natural gas. The reducing gas can also be produced by the gasification of coal.

In direct reduction the ore is heated to temperatures below its melting point. Direct energy requirements per net ton of direct reduced iron are in the order of 10,000 MJ. The product is 90 to 95% metallized and hence is suitable as a charge in blast, basic oxygen, and electric arc furnaces.

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. One exception is the fluidized bed process which requires sized iron ore particles.

CAUTION Direct reduced iron (DRI) and, in some cases, hot briquetted iron (HBI), for example, with low density or high fines content, may react with water and air to produce hydrogen and heat. The heat produced may cause ignition.

Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the ...
