Midrex is an innovative ironmaking process, developed for the production of directreduced iron (DRI) from iron ores and primarily natural gas. Midrex is a gasbased shaft furnace process that converts iron oxides – in the form of pellets or lump ore – into direct reduced iron (DRI).
· Accurate dosage of fluxes before sintering to get the required sinter strength and basicity · Accurate dosage of fluxes, coal and water for pelletizing to get the required pellets quality · Quality control of iron concentrate and pellets to reject offgrade material and prevent customer claims.
Jun 12, 2017· In MIM design there are many variations of the initial forming process where MIM manufacturers add their particular process differentiators. Whether your processes involves metals or ceramics, the key to reproducible production of precise metal parts requires a carefully planned and controlled sintering/debinding operation.

Pelletizing discs need only a single process step to form pellets, their classifying effect discharging the pellets from the disc rim within a very narrow size range. Green pellet size can be precisely adjusted by varying the disc inclination, circumferential speed, feed rate or water addition.
Sintering The Sintering Process The starting material for a sintered product is a powder of metal, ceramic, or, less often, a polymer. The powder size is often very fine (small), perhaps 20–200 microns. (One micron is × 10–6 meters.) Usually the powder is compacted in a mold of the desired end product shape, often under pressure.
Sep 21, 2011· Additives can give rise to obvious, stepwise changes both in the oxidation process and in the sintering process. Therefore, the oxidation and sintering characteristics measured in dried pellets prepared from pure magnetite concentrates can not be representative for those characteristics in dried pellets containing additives. The oxidation and sintering characteristics of magnetite iron ore ...
To make billets, Teflon pellets are dumped in bulk into a large cylinder stainless steel mold. The mold is placed in a hydraulic press. The press' arm or ram pushes the mold and the Teflon. Later the mold is removed from the press and the Teflon is removed. Lastly the newly formed billet is put into a large oven for a process called sintering.
Flash sintering (FS), a novel fabrication technique belonging to the family of field assisted sintering (FAS) techniques, has been utilized in this study to fabricate uranium dioxide (UO 2) pellets. Stoichiometric (UO ) and hyperstoichiometric (UO ) pellets were flash sintered at 600 °C within a few (2–3) minutes.

Process for monitoring a pelletizing plant for green pellets of finegrained ores, in which the humidity content of the green pellets is adjusted by adding water with consideration of the humidity content of the fine ores and humidified ores, together with optional additives, are charged to a travelling grate in an amount to form a layer and are hardened on the grate in a sintering zone by a heat treatment carried .
Pelletizing is the process of compressing or molding a material into the shape of a pellet. ... The raw material is rolled into a ball, then fired in a kiln to sinter the particles into a hard sphere. The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the...
