3. WHAT IS ferrous metal
 Ferrous metals are those which contain iron,
whilst non- ferrous metals don’t have any iron
content..
 Ferrous metals and alloys containing a high
proportion of the element iron.
 They are the strongest materials available and
are used for applications where high strength
needed.

5. When iron &steel was found
C:UsersHamshaDesktopUddeholm - Tool Steel of World Class.mp4
 The production of iron by humans began probably
sometime after 2000 BCE in south-west or south-
central Asia, perhaps in the Caucasus region.
 The basic source of iron and steel is iron ore,
which is an oxide of iron mixed with alumina,
silica, phosphorous, manganese, sulphur and
other materials.

6.  Iron Ores Required in Iron-making.
HEMATITE
MAGNETITE
LIMONITE PELLETS

7. Other raw materials in iron making.
 Coke (C)
- Supplies heat for chemical reactions
and produces carbon monoxide (CO) to
reduce iron ore.
 Limestone (CaCO3)
Used as a flux to react with and remove
impurities in molten iron as slag.
 Hot gases (CO, H2, CO2, H2O, N2, O2,
and fuels)
Used to burn coke

10. WHY IRON AND STEEL IS WIDELY USED IN THE
MANUFACTURING INDUSTRY?
High quality, aesthetic.
Low maintenance costs.
Steel is noncombustible.
Environmentally friendly.
Components can be re-used.
Strong, durable and stable.
Construction is fast compared to other
materials.
Resistant to termites and other destructive
insects.
Cost benefits compared to other
construction methods.
Components are functional.

11. Who uses the iron and
steel?
 In the motor vehicle industry.
 Aluminum.
 Concrete and wood in construction.

12. How does iron and steel
production affect our
manufacturing industry?
 Organizational structure, productivity,
efficiency, and product properties of the
steel industry worldwide.
 Reliability ,energy, materials efficiency
of conventional processes.
