sinter preparation / crusher In order for the sinter produced after the firing process to be fed into the blast furnace, it must be processed directly in downstream plants. By baking the individual raw materials together, a flat, porous mass is created from the fine ore and coke as well as other auxiliary materials, which must be broken down to ...
Conventional sintering and high-temperature sintering are different shades of the same color. In our eyes, for sintering to be considered high-temperature, it needs to happen at around 100-250 °F hotter (in the case of iron-heavy materials) than the standard sintering temp for a particular metal.

Mar 15, 2015· Depending upon the characteristics of the ore materials and the sintering conditions, daily average production rate of 22.5–44 tons/sq m/day of grate area is expected from the sinter machines. After the end of the travelling grate, the sinter passes through a spiked roll crusher and the hot screens to the sinter cooler.
atures occurring in material from the top and the highest temperatures in the centre material at the bottom. At the end of the grate the hot sinter breaks into lumps of up to half a meter in size and falls onto a rotary crusher. The crushed hot sinter may still contain pieces of 300 mm size when it issieved at about 5mm mesh size. Specimens
Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as part of a manufacturing process used with metals, ceramics, plastics, and other materials.The atoms in the materials diffuse across the boundaries of the particles, fusing the ...
The choice of manufacturing process depends not only on the chemistry of the material to be produced, but also the product's target goals, resulting coating characteristics and properties, and the application economics (deposition rate vs. product cost). In addition to the processes shown here, Oerlikon Metco may employ other processing steps to achieve the desired end result such as HDH ...
Filson sintered stainless steel sheet is generally manufactured in SS 304 or SS 316L material through a sintering process, or other series of stainless steels are also allowed upon your request. It features high temperature resistance which can work normally under 600℃ condition, while has good chemical compatibility in most acid-based liquids.

Spark plasma sintering (SPS), a sintering method that uses the action of pulsed direct current and pressure, has received a lot of attention due to its capability of exerting control over the microstructure of the sintered material and flexibility in terms of the heating rate and heating mode. Histo …
Jan 01, 2015· Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation.As shown in Figure 14.1, iron ore sintering is carried out in three stages: raw material ...
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...
Oct 19, 2016· The sintered material is discharged through a hot sinter crusher onto a sinter cooler, where ambient air is blown through the crushed sintered hot material from below. After cooling, the sinter is conveyed to a crushing and screening section where it is sized and finally conveyed either to the stock house of blast furnace or to the sinter storage.
To make sintered materials, carefully selected crushed stone and a blend of specific minerals are subjected to incredibly high temperatures under incredibly high pressure to do, in a few hours, what it takes Mother Nature millions of years to accomplish.

Sinter Plant. The function of the Sinter Plant is to supply the blast furnaces with sinter, a combination of blended ores, fluxes and coke which is partially 'cooked' or sintered. In this form, the materials combine efficiently in the blast furnace and allow for more consistent and controllable iron manufacture.
After the cooler, coarse sinter particles of larger than 5075mm are usually crushed by a secondary crusher and conveyed to the screening station where the product sinter, hearth material, and return fines are separated.
Sep 30, 2012· Compared with sintered ore, pellets have a higher iron- and a lower gang-content, and pelletizing is suitable for treating the very fine ore that will predominate in the future.

Its surface is then ignited, air is induced through the ignited layer and sintering proceeds in a vertical direction in the sinter strand's material bed. The sinter is then cooled, usually in a separate sinter cooler located at the sinter machine's discharge end. The cooled sinter is …
Mar 09, 2013· At the end of the machine, the sintered material in the form of cake is discharged into the hot sinter crusher. Here the hot sinter cake is crushed to a pre-determined maximum particle size. From here the sinter is discharged onto sinter cooler which can be either straight line or circular cooler.
sintering process, sinter cake will be crushed and screened after discharge from the machine. Sinter having size > 5 mm will go to the cooler and then it will go to BF. Sinter with size < 5 mm size fines will be re-cycled in the process. 4. Some of critical Equipments/ facilities in Sinter Plant are asunder: Sl. No. Major equipments 1.
Aug 15, 2019· The remaining sinter product is cooled in open air or in a circular cooler with water sprays or mechanical fans. The cooled sinter is crushed and screened for a final time, then the fines are recycled, and the product is sent to be charged to the blast furnaces. Generally, 2.3 Mg (2.5 tons) of raw materials, including water and fuel, are ...
The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an open-grained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.
Selective Laser Sintering (SLS) is a 3D technology that builds plastic parts layer by layer, using a range of 3D sintering materials. Whether you need fully functional prototypes or a series of complex end-parts, SLS at Materialise is a great choice for both.
The sinter cake cools to a temperature of less than 100°C at the end of the strand. After on-strand cooling, when the material reaches the end of the sinter strand, the material is discharged off the pallet cars onto a crash deck, which guides the sintered material into the spiked roll crusher.
