Design of Portable Metal Melting Furnace

Abstract

Aluminium and its alloys are ever demanded metals in production of large number of vital component s of engine pistons
car and aircrafts bodies, domestic appliances, electric tools and equipments etc .This demand is ever increasing because
of physical and chemical properties of aluminium such as it is light in weight, chemical inertness,
rustproofness,ductility,malleability,conductivity etc. Recycling of aluminium from its scrap and burr is also ever
increasing and has reached almost 50% of total supply of aluminium in the market of developed and developing
countries. This is because of high rate for the metal and its scrap ,simple process of recycling ,100% of regaining of
strength and properties by recycled material beacause of no rusting and decomposition of metal, even over a period of
100 of years. Melting of recycled scrap and burr of aluminium in a furace is a critical step in tapping secondary big
source of it ,hence, it must be controlled for cost effectiveness, fuel efficiency and ecological sustainability. And attempt
is made in this direction in the project work under consideration. The furnace manufactured under the present project
work is provided with portability by reducing the size and weight and mounting it on wheels. It is cost-affordable to any
entrepreneur of small scale industry, not only for its initial capital cost but also beacause of its running and maintenance
cost. As a furnace can be rolled on its wheels to any place, the cost of transportation of scrap and burr, its storage cost is
saved. Also it uses LPG and not electricity as the source of heat,it is economical. Also reduces pollution as compared
with traditional furnaces using natural coal as very less fumes,exhausts gases and no ash as waste product.
