A novel process for preparing direct reduction iron (DRI) and titanium nitride (TiN) from Panzhihua titanomagnetite concentrate is proposed. This process involves pelletizing, direct reduction roasting and magnetic separation. The effects of reduction temperature, coal dosage and reduction time on the phase transformation of composite pellets were investigated by X ray diffraction.Chat Online

Direct reduced iron Wikipedia. Direct reduced iron has about the same iron content as pig iron, typically 90–94 total iron (depending on the quality of the raw ore) so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.
Oct 11, 2019 Direct reduced iron Last updated October 11, 2019. Direct reduced iron (DRI), also called sponge iron,  is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
It is considered that the use of prereduced ferrous materials and sources of metallic iron such as direct reduced iron (DRI) or hot briquetted iron (HBI) improves the productivity of the blast furnace (BF). However, oxidation of DRI HBI can occur in the upper zone of the BF, which may increase the content of the reducing gases but may not decrease the coke rate substantially.
Direct reduction is the process of converting iron ore into metallic iron without melting. Direct reduced iron (DRI) is used as a high quality feed material in electric arc furnace steelmaking, oxygen steelmaking, ladle metallurgy, blast furnace ironmaking, and foundries. Normally 90 to 95 of the iron in DRI is in the metallic form. Carbon is.
Aug 31, 2012 Iron ores, comprised mostly of magnetite, are first concentrated and processed to DR grade pellets. These pellets are then fed into a MIDREX Furnace where they are reduced to metallic iron followed by discharging into hot briquetting machines, producing HBI with a metallization degree exceeding 93 percent.
Nov 11, 2020 Direct reduced iron (DRI), as a primary feedstock in ironmaking and steelmaking, must maintain strength and integrity during processing, transportation, and use to avoid any operational issue and loss of materials. Mechanical properties and structural changes of DRI during production should be understood. The first part of this study was designed to find associations among physical properties.
Dec 04, 2000 Direct reduction is the process of converting iron ore into metallic iron without melting. Direct reduced iron (DRI) is used as a high quality feed material in electric arc furnace steelmaking, oxygen steelmaking, ladle metallurgy, blast furnace ironmaking, and foundries.

Vanadium titanium magnetite dri direct reduced iron. gas based sponge iron plant using magnetite ore DRI Direct Reduced Iron, or Sponge Iron, comes as the result of a reducing process where iron ore Each process is designed based on the relative amounts of titanium, vanadium and iron. Major sources of vanadium bearing magnetite ores are scattered.
HICS is a pyrometallurgical process capable of turning iron ore into at least a 90 per cent metallic iron product through direct reduction. The process revolv es around forming an iron chloride, vapourizing the iron and leaving behind the phosphorous and waste (which may contain other economic minerals such as vanadium). Then, a reaction with.
