Iron Making Process

As iron is the main component of steel it firstly needs to be made. Iron ore, lime and coke are placed into blast furnace and melted. The resulting liquid is known as molten iron is then formed. As molten iron still contains around 4 to 4.5 % impurities such as carbon which in turn make the metal brittle, they need to be eradicated.

Primary Steel Making

There are two main methods for making steel and these are basic Oxygen Steel (BOS) making and Electric Arc Furnace (EAF). BOS methods for example involved adding scrap (recycled) steel to molten iron when in furnace. Oxygen is then forced through liquid (The Bessemer Process) to cut impurities in the molten metal down to 0.5% – 1.5%.

Alternatively with the EAF method, recycled steel is fed into electrical arc furnace along with the molten iron which is then heated to around 1650 degrees Celsius in order to convert it into high grade steel.

Secondary Steel Making

Newly formed molten steel needs to be adjusted to make the perfect steel composition. This is done by either manipulating the temperature or removing certain elements. This may include processes such as degassing, stirring, Iadle Injection or argon bubbling.

Casting

We have bones of steel the next step is to pour it into cooled moulds. This causes the metal to cool quickly. Once cooled the metal is then cut into desired lengths depending upon the application e.g.: slabs and plates, blooms for sections such as beams and billets for long products such as wiring or thin pipes.

First Forming

Also known as Primary Forming, the initial shapes of slabs, blooms, and billets are formed into their various shapes usually by hot rolling. Products that are hot rolled are then divided into flat products, long products, seamless tubes, especially products for one last stage of processing.

The Manufacturing, Fabrication & Finishing Process

Finally, a variety of secondary forming techniques including shaping, machining, jointing and coating give the products their tall –tale shapes and properties.

So there you have it, the entire steelmaking process in six steps if you are in need of particular metal part then why not contact us. We have skills and the experience to construct just about anything you want.
