CUPOLA FURNACE
Definition:
Cupola furnace is a melting device. We used this device in the forging operation where Cast Iron,
Bronze, and other alloying elements are melted.
This is a very old device we used in manufacturing for melting because this system produces
good cast iron from Pig Iron. The shape of this device is cylindrical but others size is also
available.
While choosing a cupola furnace we keep some valid factors that are Melting Point
Temperature, Shapes and many more.
Construction of Cupola Furnace:
, The Cupola Furnace is consists of:
Legs
Slag Hole
Sand Bed
Tuyers
Preheating Zone
Melting Zone
Charging Door
Brick lining
Spark Arrester
Let me describe these parts of cupola furnace in details:
Legs:
Legs are provided for supporting purposes.
Slag Hole or Slag spout:
The slag hole is used for removing or extracting the slag from the melting iron.
Sand Bed:
This is in taper form and from this, the melted iron comes out easily.
Tuyeres:
By tuyeres, we enter the gas to the proper burn of fuel.
Preheating Zone:
In the Preheating zone, the heating process started and heats the metal charge about 1090
degrees Celsius.
Melting Zone:
In the melting zone, we do not provide much heat to melt the metal charge because it’s already
melted in the preheating zone with a temperature of about 1090 degrees Celsius.
Charging door:
From here we supply the charge to the furnace. The various charges are for the cupola furnace
are Pig Iron, Coke and limestone.
Brick lining and Steel shell:
The shell of the cupola furnace is being usually made of steel and it’s called a steel shell.
Spark Arrester:
This device used in the system for preventing the emission from the fireplace.
