Nov 21, 2014· Sinter is normally the major component of the blast furnace (BF) charge burden. Sinter consists of many mineral phases produced during process of sintering of iron ores. The quality and properties of sinter are dependent on the mineral structure of sinter. However, since the sintering conditions are usually not uniform throughout the …

Apr 02, 2010· The total energy use distribution [24] by various units of the steel plant (coke ovens, sinter plant, blast furnaces, steel shop, rolling mills, and power plant) is shown in Figure 4.2.8. It can be noted that the major share (72%) of energy is required during iron making which includes coke making (12%), iron ore sintering (6%), and blast ...

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 properties of the ingredients. The purpose of sinter are to be used converting iron into steel.

Jul 15, 2014· The sinter basicity level should be such that it eliminates direct flux charging in the blast furnace. MgO in the sinter is to be maintained to have proper MgO in the BF slag for making the slag fluid. For high alumina iron ores, MgO in BF slag is to be maintained in the range of 8 to 10 %. FeO in the sinter must be brought down if does not ...

A blast furnace is a block that smelts ores, raw metals and metal armor and tools twice as quickly as a furnace but cannot smelt anything else. It also serves as an armorer's job site block. A blast furnace can be picked up by any pickaxe. If mined without a pickaxe, it does not drop anything. Blast furnaces drop their contents when broken. Blast furnaces can …

Answer: For three reasons. One, Pellet swells after heating. Swelling is upto 200% by volume. This increase in volume reduces permeability of ascending gases inside furnace. Secondly, sinter being irregular in shape offers more permeability than pellet beacause of round shape of pellets. Thirdly,...

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 …

The mixture is thus baked from top to bottom. At the end of the line, the (now) sinter cake is discharged on a crash-deck, where it is crushed and cooled. Sinter has the perfect chemical composition, grain size and physical attributes to be used in the blast furnace. Sinter typically accounts for 90% of the blast furnace metallic burden.
