Direct reduction iron(DRI) also named sponge iron, It is the raw material for electric furnace steelmaking. In the direct reduced iron production process, no matter what kind of production process is, all need use briquette machine to complete briquetting raw materials, mixing all materials such as iron ore, iron concentrates, coke, coal and bidner together, to press them into briquettes by

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

Jun 18, 2021 The direct reduced iron briquetting machine has a plate-drawing cylinder located behind the lower mold of the main machine. The plate-drawing cylinder forms the bottom of the cavity with the mold sleeve in the front position, and forms a space at the bottom in the rear position, which is conducive to the falling of the cakes and has the

DRI (direct reduced iron) or another name as sponge iron, is a kind of mid product in the steel making process. It gained great prominence as a substitute for the metal scrap (steel) in the furnace. The briquette machine for DRI normally has two types – hydraulic type and hydraulic roller type

Direct Reduced Iron Pellets with Binder The Koeppern Difference In addition to larger roller press briquetters capable of producing over 50/tons per hour, Koeppern is a leading manufacturer of both cold and hot briquetting machinery and related systems, providing our customers with additional briquetting

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

The 4th quarter 1982 issue of Direct From Midrex first mentioned a new direct reduced iron (DRI) product from Midrex called hot briquetted iron (HBI). Midrex was not the first to produce a hot briquetted form of DRI (Fior de Venezuela had produced and shipped a product in the late 1970s), but we did help establish HBI as the steel industry’s

148.245 Direct reduced iron (DRI); lumps, pellets, and cold-molded briquettes. (a) Before loading DRI lumps, pellets, or cold-molded briquettes - (1) The master must have a written certification from a competent person appointed by the shipper and recognized by the Commandant (CG-ENG-5) stating that the DRI, at the time of loading, is

Cold briquetting. In the cold briquetting process, the material is inputted into the briquetting machine at ambient temperature. In this process, according to the type of the input material, two types of products are known, Briquette of Sponge Iron Fine (Cold Briquetted Iron-CBI) and Briquette of Sponge Iron Pellet (Cold Briquetted Iron and Carbon - CBIC)

In cold briquetting process, raw materials are entered into briquetting machine in ambient temperature. HBI is produced in the process of briquetting from hot direct reduced iron (HDRI) and in the temperatures above 650 degrees Celsius and is the easiest and safest production of DRI in the case of transportation around the world
