Mechanical Engineering Mechanical Engineering TechnologyTechnologyThe Production of Ferrous MetalsThe Production of Ferrous Metals At the end of the lesson students
should be able to:1. Define the three main ingredients
used in the production of iron and steel.2. Draw and explain the diagram of
production of iron and steel (ferrous metals).
3. Define other processes involved in the production process.
4. List the end products of iron and steel.
The Production of Iron & Steel.The Production of Iron & Steel.The importance of metals to man in today's world cannot be overemphasized because we use them in our everyday life.Metals are divided into three main groups; Ferrous, Non-ferrous Alloys.

Non-Ferrous MetalsNon-Ferrous MetalsThese contain little or no iron and
they do not rust when exposed to air.

These contain mainly iron and they These contain mainly iron and they rust easily when exposed to air.rust easily when exposed to air.
