Australia's iron ore makes a significant contribution to our economy, with a gross added value of over $100 billion each year.However the process of turning the world's iron ore into steel currently contributes around seven per cent of global greenhouse gas emissions.There are a number of ways of reducing the carbon footprint of the iron …
FLOW-3D CAST's cast iron model describes the solidification of hypo- and hyper-eutectic iron-carbon-silicon alloys.It predicts the formation of graphite, austenite (or gamma-iron) and carbide phases during the eutectic reaction. Volume changes during cooling and solidification are coupled with shrinkage and porosity formation models.

For iron making process, it consists of several blast furnaces with different volume. These blast furnaces are the units in ...
Example 1 Data flow diagram (DFD) This type of diagram is used to map the flow of data through an information system or process. Showing all the accompanying inputs, outputs and functions that relate to the capture or use of data and where that data lives.
By the later second millennium AD, iron production was a key economic industry in western Uganda, and Mwenge was a prominent centre of production, highly regarded for the quality of the iron it produced.
Figure 1 Drawing of an ironmaking blast furnace with hot-blast stove. Source: The German Steel Federation (WV Stahl) In order to make steel, iron must be extracted or won from iron ore. Blast furnacing, smelting and direct iron reduction are the current ironmaking processes.
For a standard process, there are several licensors like UOP, Axens, Lummus, etc. & they are responsible for developing the PFD. Process flow diagrams of open art process units like CDU (Crude distillation unit), and VDU (vacuum distillation unit) can be found in the literature and encyclopedia of chemical technology.

In the melting zone the iron begins to melt and forms strongly carbon-containing pig iron! Tapping zone. The molten pig iron finally collects in the hearth of the blast furnace together with the slag, which is also liquid. Due to the higher density of the pig iron, the pig iron can be cut off at the lowest point of the blast furnace (called ...
