2.  INTRODUCTION
 CONSRUCTION
 OPERATION
 ZONES OF CUPOLA
 APPLICATIONS

3.  Cupola is employed for melting scrap metal, mostly
pig iron which is use din production of Iron castings.
 It is an economical furnace for the production of grey
cast iron, nodular cast iron and some malleable iron
castings.
 It is obtained in different sizes and can be operated for
long a time.

5.  Preparation of Cupola..
 Lighting the fire in the coke bed.
 Charging of Cupola.
 Melting.
 Slagging and metal tapping.
 Dropping down the Cupola bottom.

6.  Superheating, Combustion or Oxidizing Zone.
 Reducing or Protective Zone.
 Melting Zone.
 Preheating Zone.
 Stack Zone.

7.  It is the zone where combustion takes place. It extends
from the top of the tuyeres to a surface boundary
below which all the Oxygen of air is consumed by
combustion, chemical reaction that takes place in the
zone is
C(coke) + 02 (from air) -> C02 + Heat
 The temperature in this zone is about 1800°C.

8.  It extends from the top of the combustion zone to the
top of the initial coke bed.
 The CO2 produced in the combustion zone moves up
and is reduced to CO. The temperature also drops
to 1650°C.
C02 + C2 -» CO – Heat

9.  It includes the first layer of pig iron above the initial
coke bed.
 In this zone, the pig iron is melted. The following
reaction takes place.
3 Fe + 2 CO -» Fe3C + C02

10.  It includes all the layers of cupola charges placed above
the melting zone to the top of the last charge.
 The layers of charges are heated by the out-going
gases.
 The temperature in the zone may be up to 1050°C.

11.  It is the zone beyond the pre-heating zone, through
which the hot gases go to the atmosphere.

12.  It is highly used in iron foundaries for melting
purpose.
 It is used to melting scrap metal or pig iron.
 It is also used for duplexing and triplexing operations
for making steels.
 It is also used for melting some copper base alloys etc.
 It is mostly used in the production of cast iron.
