Chilled Cast Iron. Chilled cast iron consists two layers of which one layer has white cast iron properties and other one has grey cast iron properties. This type of iron is used for casting process in which grey cast iron layer is provided in inner surface and white cast iron layer is provided as outer surface. Hence the casting molds serve longer.

Extraction of Raw Materials (1) The key raw materials in steelmaking include iron ore, coal, limestone, and recycled steel (not extracted). Actual steel is mostly iron ore and less than 2% carbon, the other materials are used in the manufacturing of crude steel. Iron ore is mined in about 50 countries (worldsteel association, 2014).

The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts.

Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something. With titanium, however, you make it one batch at a time.
