AIM

Melt aluminum at 700 C

INTRODUCTION

• Aluminum can melt by various process of furnace like coal, gas, etc. But they all are

very complex not good for economically and environmentally.

• So here, we present the Induction furnace and it is much better then others. Electric

heating is a process in which electric energy is converted to heat.

• First, we required highly resistance wire like Nichrome [40ft of 20avg(0.032inch)] .

Fire bricks K23 for thermal insulating(2300 F). A small crucible for aluminum scrap

and asbestos sheet for the bricks support.

BENIFITS

Its works at single phase power supply(230v – 10amp)

Less time consuption

Easy to handle and maintenance

No skill labour required

APPLICATIONS

Induction furnaces may be used for manufacturing, heat engineering

Aluminum casting industries, in larg scale production

The de-gassing of cathode ray tube components is done by

induction heating.

• There are only 25 min. for melt the aluminum at single

phase power supply.

• Power consuption of this event is 6 – 7 kwh. [P = I Rt]

• NiChrome Wire is composed of Nickel & Chromium.

• NiChrome Wire is the optimal wire choice for foam cutters for a variety of

reasons, but particularly because it is resistant against corrosion and

oxidation at very high temperature.
