Furnace Casing About
What is FurnaceCasting?
Furnace Casting refers to the melting of metals ina furnace and pouring the molten metal into molds to form a desiredshape (castings). This process is widely used in foundries for producing partsin steel, iron, aluminum, copper alloys, etc.
Core Concept
- Metal is melted in a furnace (induction, electric arc, cupola, etc.).
- Molten metal is poured into a pre-made mold (sand, ceramic, metal die).
- The casting is allowed to solidify.
- The mold is removed to extract the cast component.
- Casting is cleaned, machined, or heat-treated as needed.
Types of FurnaceUsed for Casting
| Furnace Type | Fuel Source | Common Uses |
| Induction Furnace | Electric | Steel, stainless steel, copper |
| Electric Arc Furnace (EAF) | Electric arc | Steel scrap melting |
| Cupola Furnace | Coke | Cast iron |
| Crucible Furnace | Gas, oil, electric | Small batch melting (aluminum, bronze) |
| Rotary Furnace | Oil/gas fired rotating chamber | Lead, aluminum |
| Reverberatory Furnace | Gas-fired | Non-ferrous bulk alloys |
