The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel.

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.
FLOWCHART 1. Convert the following flow chart into a paragraph of about 150 words. The process of making cement is described in this flow chart. The two raw materials used in theprocess are limestone and clay. Limestone is crushed, sized, dried and stored in storage silos. In the same way, Clay is washed, crushed, and dried in
Electric Arc Furnace Steelmaking Process. 1. Feeding. The operation of adding molten iron or scrap steel to the electric furnace is the first step of the electric furnace steelmaking operation. 2. Slagging. The operation of adjusting the slag composition, alkalinity, viscosity and reaction ability in steel and iron production.

Iron and Steel Manufacturing Industry Description and Practices Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufac-turing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is con-verted to steel in a basic oxygen furnace ...
3), Magnesia (MgO) or Calcia (CaO) that entered with the iron ore, pellets, sinter or coke. The liquid slag then trickles through the coke bed to the bottom of the furnace where it floats on top of the liquid iron since it is less dense. Another product of the ironmaking process, in addition to molten iron and slag, is hot dirty gases.
Wood received at a pulp mill may be in several different forms, depending on the pulping process and the origin of the raw material. It maybe received as bolts (short logs) of roundwood with the bark still attached, as chips about the size of a half-dollar that may have been produced from sawmill or veneer mill waste or pre-chipped from ...

It is in the blast furnace that extraction of iron occurs. The [randpic] flow ch
What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
2. Generalized Process Flow Diagram A general flow diagram for the production of raw steel from iron ore is presented in Exhibit 2. In general, the process involves (1) beneficiation of the iron ore, (2) either direct-reduction or reduction in an iron blast furnace, (3) processing in steelmaking furnaces, and (4) casting. Ironmaking
Sponge Iron, also known as Direct Reduced Iron is produced from Hematite Iron ore (5 to 18 mm size) by removing the oxygen by direct reduction process using non coking coal as the fuel and reducing agent in Rotary Kiln. Sponge iron is rich in Metallic Iron (Pure Iron) with consistent chemical & physical characteristics.
Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H₂ and CO content.
The Modern Steel Production Process . Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.
Afterward, iron went through a final iteration, which most resembles today's steel material. In India, ironworkers developed an iron smelting process that combined the perfect ratio of iron to carbon. Using crucibles, or clay containers, the ironworkers would blend iron and charcoal pieces together in a high-temperature furnace.
CNC milling is a substractive fabrication method that uses computer numerical controls systems for automating the process. Milling Process We could limit ourselves to describing the fabrication process only but giving an overview of the complete flow gives a more wholesome picture.
When the material exits the mill, the iron ore is classified using cyclones or vibrating screens that separate fine and large particles. The large particles are diverted back into the crusher and the fine particles will undergo a spiral gravity separation process. 5. …
p.a. Whereas mini mills operate successfully at 100,000 tonnes p.a. and upwards to 1.5 to 2.0 million tonnes p.a. 1.3 The Steelmaking Process Integrated steelmaking operations fall into three main phases: Reduction: lronmaking Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances,

Steel production, from iron and/or recycled scrap, is a multi-stage process which results in the production of a variety of slags.Several of these slags contain hydraulic or latent hydraulic compounds, and can display …
In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which is produced from iron ore by means of direct reduction (= DRI or directly reduced iron) and that is then further reduced and smelted in an electric furnace.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runners that …
