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.

12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the
Iron-working technologies broadly include both the winning of iron from an ore (smelting) and the processing and shaping of smelted iron metal into a finished object (smithing). …
A Process Flow Diagram (PFD) is a type of flowchart that illustrates the relationships between major components at an industrial plant. It's most often used in chemical engineering and process engineering, though its concepts are sometimes applied to other processes as well.
How to make a process flow diagram. Creating a process flow diagram is a structured approach to visualizing and understanding the steps and flow of a process. Whether you're mapping a complex manufacturing operation or a simple business procedure, a clear and accurate PFD is invaluable. Let's dive into the steps necessary to create an effective ...

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.
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
Iron and steel both are the alloys of carbon in iron. The basic difference lies with the carbon percentage in these alloys. It is better to understand this in terms of iron carbon diagram and this is a very well known diagram in metallurgy. It is basically binary phase diagram between iron and carbon. The diagram shows the different stable
