The Melter Should not only understand the operation of the equipment he required to use .
He should know Nature & Metallurgy of Various Cast metals , their behaviour During solidification & cooling , their physical & mechanical properties
Therefore the need arise to understand in depth about the advanced casting Process.
We are Discussing some of the Melting Equipments in Detailed here
a) Coke Fire Furnace
b) Oil & Gas Fired furnace
ii)Open hearth Furnace
a) Direct Arc Furnace.
b)Indirect Arc Furnace.
c)Electric Induction Furnace
Simplest of all the Foundries
Used for Melting many Ferrous & non Ferrous Metals, Copper based Alloys .
Crucible is made of Chamotte or clay or graphite For melting said materials.
while for melting Al & zinc base alloys these are made of Steel & CI .
Used for Melting non ferrous metals such as brass , Bronze & aluminium .
Generally installed in Pit
Has a Steel cylindrical Steel Shell, lined on inner side with refractory bricks , closed at the bottom with a grate & covered at top with a removable lid.
Metal to be Melted is contained in a crucible which is embedded in burning coke .
