MELTING PROCESS

INTRODUCTION

                 A foundry is an organization that manufactures metals, such as steel, aluminum, or bronze, and puts them into molds to create a variety of products such as machinery parts, sculptures, or tools.
Molds are usually made from sand or ceramics and are shaped to the desired shape of the final product by heating metal to a high temperature using a furnace.
The molten metal is allowed to cool and solidify, and then the mold is broken open to reveal the finished product.

FURNACE

There are several types of foundry furnaces that are commonly used:

Cupola furnace: A vertical furnace that is fueled by coke and is used to melt iron. It is the most traditional type of foundry furnace and is still widely used today.

Induction furnace: An electric furnace that melts metal using electromagnetic induction. It is efficient and precise, and can be used to melt a wide range of metals.

Electric arc furnace: An electric furnace that melts metal using an electric arc. It is used to melt steel and other alloys.

Crucible furnace: A small, handheld furnace that is fueled by gas. It is used for small scale operations, typically for melting precious metals.

Resistance furnace: A furnace that melts metal using electrical resistance. It can melt a variety of metals and alloys and is used in many different industrial settings.


Coreless Induction furnace: This furnace is similar to an induction furnace, but doesn't have a core and is commonly used for melting small to medium sized quantities of non-ferrous metals.

Tilting Furnace: A furnace that tilts on its axis to pour the molten metal into a mold. This allows for easy and precise pouring.

RAW MATERIAL SELECTION 

                Raw material selection is the process of choosing the appropriate materials to use in a manufacturing process. In a foundry, the raw materials typically include the metal that will be melted and poured into molds, as well as any additional materials that will be used to make the molds or to add desired properties to the final product.

When selecting raw materials for a foundry, the following factors should be considered:

Chemical composition: The chemical composition of the metal will affect the properties of the final product, such as its strength, ductility, and corrosion resistance.

Quality and purity: The quality and purity of the metal will affect its melting point, fluidity, and shrinkage during solidification.

Cost: The cost of the raw materials will affect the overall cost of the manufacturing process.

Availability: The availability of the raw materials will affect the lead time for the manufacturing process.

Environmental impact: The environmental impact of the raw materials and their extraction process should be considered.

Standards and Regulations: Raw materials needs to be selected keeping in mind the standards and regulations that needs to be met in the final product.

The selection of raw materials will depend on the specific requirements of the product being manufactured and the manufacturing process used. It is important to select raw materials that will meet the desired specifications for the final product, while also being cost-effective and readily available.
