The primary advantage of the early blast furnace was in large scale production and making iron implements more readily available to peasants Cast iron is more brittle than wrought iron or steel, which required additional fining and then cementation or co-fusion to produce, but for menial activities such as farming it sufficed
Iron ore is utilized in the production of steel- the process of steel-making involves the removal of impurities from raw iron and the addition of alloying components to produce the desired
The third option for pig iron is to push the refining process even further and create steel, which we'll examine on the next page Iron Advantage Between the 15th and 20th centuries, some countries had an industrial leg up on the competition due to the availability of iron ore deposits
Some examples of ferrous metals would be mild steel, cast iron, high strength steel, and tool steels Examples of non-ferrous metals would be copper, aluminum, magnesium, titanium, etc To make steel, iron ore is first mined from the ground
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue" The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent
