INTRODUCTIONCONSRUCTIONOPERATIONZONES OF CUPOLAAPPLICATIONS
CONTENT
INTRODUCTIONCupola 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.
CONSTRUCTION
Preparation of Cupola.. Lighting the fire in the coke bed. Charging of Cupola. Melting. Slagging and metal tapping. Dropping down the Cupola bottom.
OPERATION
Superheating, Combustion or Oxidizing Zone.Reducing or Protective Zone.Melting Zone.Preheating Zone.Stack Zone.
ZONES OF CUPOLA
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.
COMBUSTION ZONE
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
REDUCING ZONE
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
MELTING ZONE
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.
PREHEATING ZONE
It is the zone beyond the pre-heating zone, through which the hot gases go to the atmosphere.
STACK ZONE
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.
