ADVERTISEMENTS: In this article we will discuss about the metabolism of iron in human body with the help of suitable diagram. Distribution of Iron: Iron is distributed in the body: (a) As iron porphyrins in haemoglobin, myoglobin, and also ADVERTISEMENTS: (b) As iron enzymes in alase, cytochrome and peroxidases. Besides these, the iron is also [.]

During the assembly process, an iron is removed from the production line and taken apart by an independent department to look for errors. Any mistakes result in the whole batch of irons being checked and corrected if necessary. After the product is assembled, a worker also checks the iron for electrical functionality and water integrity. ...

The smelting and refining process for iron and steel in the BFBOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas(CO) generated by the oxidation of the carbon(C) in coke. ...

A process flow diagram is a graphical tool most commonly used by business process management professionals (BPM) and chemical engineers. PFD helps to understand the process, provide quality control, and increase efficiency. It is used to get a topdown understanding of how different types of equipment and chemicals work in the industrial plant.

iron processing iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

Conventionally, the complete FeC diagram should extend from Fe to carbon, but it is normally studied up to around % carbon as is also illustrated in Fig., because iron alloys of practical industrial importance contain not more than 5% carbon. Thus, this diagram is only just a part of the complete FeC equilibrium diagram.
