The Metal Casting Process: Take a Foundry Tour
A trip through a foundry from pattern to product. This series follows a cast iron or steel product through the metal casting process in a traditional foundry. Iron melts at 2750°F and steel at 2500°F. Casting is the process of creating metal objects by pouring liquid metal into molds, where it cools and hardens into the mold's shape.

The 6 Steps To Modern Steel Production Explained
Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make the metal brittle, they need to be eradicated. Step 2 does exactly this. Step 2 – Primary steel making

Iron- and Steel-Making Process | SpringerLink
Iron is extracted in the form of metallic iron (Fe) by reducing the oxide ores with a reducing agent. The principal agents commonly employed to serve this reduction process are the naturally occurring forms of carbon such as coke, charcoal and coal. In order to extract the iron, Fe (55–60%)-rich ore is usually used.

THE BLAST FURNACE
As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'. Molten iron ore is 'tapped' at the bottom of the blast ...
