What are Ferroalloys? (II)

We normally call it steel industry, but more accurately, it is the iron & steel industry.In other words, there are iron industry and steel industry. Normal people would not know what the difference between them is, but it is quite essential to understand them before we move on.
1.  When we say ‘Iron Plant,’ it produces products with iron ores. On the other hand, ‘Steel Plant’ is producing steel products mainly with steel scraps.
    2. If so, what is key difference between Iron and Steel? It is a strength in one word. More accurately, the content rate of carbon because carbon decides on the strength of steel products. 
      - Iron: If the carbon rate goes over 2%, it becomes solid like a stone, and it is not bendable any longer and just breaks when a force is added. 
      - Steel: if the carbon rate stays below 2%, it is still bendable and deformed when a force is added rather than breaking.

What are Ferroalloys? 

Ferroalloys are namely alloys one or more alloying elements with iron. 

For example, Ferrosilicon is an alloy made of iron and silicon (Fe + Silicon).
In the same way, Ferromanganese is made of iron and manganese. 

 


@SUN Inside

Actually, you should understand very basics of the steel industry in order to understand the ferroalloy industry. We can divide the steel industry into three groups as below:

  • Mining Industry 
  • Ferroalloy Industry
  • Steel Industry (more accurately Iron & Steel Industry)
In fact, more than 99.9% steel products we are using right now are made after the process of using ferroalloys. So much so, ferroalloy takes a big part among entire value chain of steel industry.
