Blast furnace Facts for Kids Kiddle encyclopedia

A blast furnace is usually built with a steel case and bricks made of magnesia inside the case. Magnesia is very resistant to heat. It does not melt. The furnace is cooled with water running inside part of the case and bricks. The process of making iron is simple. Iron ore is basically iron oxide. Iron is made by removing the oxygen.

Ironmaking Processes Shropshire History

Siemens-Martin Open Hearth Process. As soon as all the steel has melted, slag forming agents such as limestone are added. The oxygen in iron oxide and other impurities decarburize the pig iron by burning the carbon away, forming steel. To increase the oxygen contents of the heat, more iron ore can be added.

Iron Essential Chemical Industry

Iron is produced by reduction of iron ore, which is often a mixture of oxides, using carbon, carbon monoxide, and hydrogen. While the blast furnace is the dominant reduction process other technologies are emerging which operate on a smaller scale. These are linked to locations where there is a plentiful supply of natural gas or low-grade coal.

Jul 29, 2019Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.
