There are four metallurgy areas
1-
Physical metallurgy 2-
Chemical metallurgy
3-
Extractive metallurgy 4-
Mechanical metallurgy
·
Metallurgy operations
1-
Inspection and testing 2-
Corrosion Engineering
3-
Nuclear Engineering 4-
Foundry Engineering
·
Foundry
is a place where we melt and cast metals and alloys
·
Casting is
a process in which we use a mold to reshape the metals and alloys
Steps of foundry operation:
·
First of all I
need molten metal or alloy
·
Pattern/design is
used to make mold
·
Molding
·
Sand
testing/preparation
·
Inspection and
testing of casting
·
Chemical
composition verification
·
Microstructure
examination
·
Smelting
is a process in which physical and chemical changes takes place
·
Melting
is a process in which only physical changes takes place
·
Pattern
is a design used to make mold. It is of two types
1-
Master pattern (Steel) 2-
Pattern (Wood)
·
Ingots
are big pieces of metal or alloy
Basic steps in a foundry are
·
Melting
·
Molding
·
Casting
Foundry engineering setup
Foundry shops:
Two types of shops are
1-
Essential shops
(Production areas)
2-
Auxialry shops
·
Core is
a mold used to get internally hollow shape
