Hot DRI in the form of pellets, lumps, fines at a temperature of 650-850 deg C is passed through hot briquetting machine where the product is pressed between the rolls at extremely high pressure to produce highly compacted pillow shaped material called hot briquetted iron (HBI)

General Manager - Hot Briquetting Maschinenfabrik K PPERN GmbH & Co. KG K nigsteiner Str. 2 D-45529 Hattingen/Ruhr, GERMANY Tel.: (+49 2324) 207-0 Fax.: (+49 2324) 207-207 Resume. Hot briquetting is a reliable, fully developed industrial concept for the passivation of direct reduced iron produced with the various processes of direct reduction

Hot DRI briquette machine. Hot DRI is a better material than cold DRI, it is a material with much higher temperature (normally around 650-700 Celsius) and stronger plasticity, the hot DRI briquette is with densified form and lower gas content. Hydraulic briquetting machine is a way to make the hot DRI briquette with a reasonable investment

Following its industrial development in the 70s and 80s, hot briquetting is now a fully-accepted, reliable technology for the passivation of direct-reduced iron (DRI) to turn it into the more convenient form of hot-briquetted iron (HBI). Materials are briquettable under hot conditions if binding characteristics are activated at high temperatures. The most common application is the production of hot briquetted iron (HBI) from direct reduced

Downstream of the direct reduction process, a further stage may consist of briquetting or smelting hot DRI pellets. In the former case the Magaldi Ecobelt DRI has the function to cool down the DRI pellets, since the working temperature of the briquetting machine is generally in the range 500 700 C

The feeding system is essential for the hot briquetting press efficiency: SAHUT‐CONREUR. has developed a force‐feeder equipped with one screw specially adapted for degasing and predensifying the hot DRI and feeding the rolls. Made of special refractory stainless steel adapted to the high temperature, the force‐feerder tank is also

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

Hot briquetting JEIL MACHINERY CO., LTD. is the enterprise which can supply hot briquetting machine and plant with world class technology. Meantime, we have supplied hot briquetting machine equipments to POSCO, PNR, POSCO PLANTEC, KS Nickel in Korea, Shagang Steel in China

Jan 17, 2013 Hot briquetting of the DRI can eliminate this concern by drastically reducing the surface area, while improving the heat conduction capacity of the material through a compaction process. Process Hot briquetting is carried out by compacting feedstock at temperatures ranging between 250 and 800C through a pair of briquetting rollers

Sep 08, 2018 For the ‘Hytemp’ pneumatic transport system, the product is transported by means of a carrier gas to the surge bins located at the steel melting shop, for a controlled feeding to the electric arc furnace. For production of HBI, hot DRI is continuously discharged at greater than 700 deg C to the hot briquetting machines arranged below

Most applications of briquetting in the iron and steel industry involve waste materials, such as mill scale and process dusts, sludges, and filter cakes [27]. In the DR industry, a number of facilities briquette their hot DRI product to produce a higher-density product for safer shipping

DRI does not allow the heat to escape. So, overheating and meltdown of DRI (which is stored in piles) occurs. So due to this Hot Briquetting process has been developed. In this technique, the direct reduced iron is applied with high pressure immediately after it reduction at high temperatures. The high

DRI fines These are the by-product of the DRI manufacturing process, pellets or briquettes, and are often 4mm in diameter or less. Although smaller than normal DRI pellets, this product is essentially DRI pellets and will behave in a similar manner, so it should be treated with the same caution: it should be kept dry at all times, the holds should be inerted and temperature and gas monitoring
