ABSTRACT

A wide variety of sizes and shapes of simple and intricatenature can be produces in different metals.

Ferrous materials are the must important metals/ alloy in themetallurgical and mechanical industries because of their very

extensive use. Originally the electric furnace are used for the manufacture of

relatively small amount of high grade total steels and alloysteels.

In completion if melting the moulding are set by the mouldingsand. The mould material should be such that mould cavityretianing its shape until the molten metal solidifiescompletely.

The main objective of the present project is to study “Theprocess of metal casting by using electric furnace.”



CASTING

Casting is the process ofpouring the molten metal intoa mould and allowing it to

solidify. By this process, intricate parts

can be given strength andrigidity, not obtainable by any

other method. Although all metals can be

cast, iron is especiallyadaptable because of itsfluidity, its small shrinkage.



ELECTRIC FURNACE

In 1878 Siemens made use

electric current for melting iron.The first direct electric are steelmaking furnace was placed inoperation by the Frenchmetallurgist, Paul Louis ToussaintHeroult in 1899. Initial are furnaceswere of low capacity (even<4tons).The first are furnace for steelmaking introduced in U.S.A in 1904was of 4 tons capacity and utilizedtwo electrodes.

Since 1945, growth in themanufacture of carbon steels bythe electric process andimprovements in furnaceconstruction have been largelyresponsible for the continued

expansion of the electric furnacecapacity. Some modern large

MOULDING

The prepared mouldingsand is packed rigidlyaround the pattern andwhen the pattern iswithdrawn a cavity

corresponding to theshape of the patternremains in the Sandand is known as mould

cavity.



DIFFERENT SANDS USED IN FOUNDRY

Green sand Dry sand Loam sand

System sand

The principal constituents of moulding sand are

Silica sand Binder Additives and water



PATTERN

A pattern is the replica model of thedesired casting, which packed ofembedded in a suitable mouldingmaterial produces a cavity calledmould.

This cavity when filled with moltenmetal produces the desired castingafter solidification of the pouredmetal. The process of making apattern is known as pattern making.

PATTERN MATERIAL Non-metal like a wood Metal type like a Alluminium and

Alluminium alloys, steel, cast iron,brass, white metal.

ADVANTAGES

An induction furnace can melt relatively small

quantities (from1.5kg up to 12tons) of a wide variety of metal and alloys quickly,conveniently and clearly

A high frequency induction furnace has a simpler construction as compared to core type (low frequency) induction furnace because it eliminates the laminated iron ore and the need for the channels of molten metal. High frequency induction furnaces do not need a warming up time.

A number of alloys one after the other can be easily melted in this type of furnace.

High frequency induction furnaces do not need

a warming up time.

FOUNDRY SECTION



CONCLUSION:

---- Size is a not a limitation.

---- Intricate components can be made with accuracyand good surface finish.

----There are several metals which can only be cast.

---- Metal casting can be adopted for job works as wellas far mass production.

---- Casting in general resistance creep under hightemperature.
