When it comes to casting metals, the type of furnace you use can make a big difference.
Different furnaces are designed for different types of metals and casting processes.
Here’s a breakdown of the most common types of furnaces used in various casting industries.
What Kind of Furnace is Used for Casting? 7 Types You Should Know
1. Crucible Furnaces
Crucible furnaces are commonly used for casting metals with low melting points like brass, bronze, and aluminum.
The metal is melted in a crucible, which is a heat-resistant container made of materials like graphite, clay, or ceramic.
2. Stationary Bale-Out and Hydraulic Tilting Crucible Furnaces
For aluminum casting, stationary bale-out or hydraulic tilting crucible furnaces are the most commonly used.
These furnaces offer flexibility for frequent alloy changes, extended shutdowns, and have a small footprint for facilities with limited space.
The heat source for these furnaces can be natural gas fired, oil fired, electric resistance heated, or electric induction.
3. Gas Fired or Electric Resistance "Globar" Wet Bath Reverberatory Melters
In larger capacity sand or lost foam casting facilities, gas fired or electric resistance "globar" wet bath reverberatory melters are utilized.
These furnaces are designed for high-volume production and can handle larger quantities of metal.
4. Gas Fired Dry Hearth Furnaces
Gas fired dry hearth furnaces are another option for larger casting facilities.
These furnaces are known for their efficiency and ability to handle large amounts of metal.
5. Gas Fired "Stack" Melters
Gas fired "Stack" melters are used in high pressure die casting industries.
These furnaces can range from crucible furnaces to central reverberatory melting furnaces, low energy electric or gas fired holding furnaces, automatic dosing furnaces, and electrically heated distribution systems.
6. Electric Resistance Crucible Furnaces
For small to medium sized die casting shops or captive shops casting parts for their own product line, gas fired or electric resistance crucible furnaces are commonly used.
Crucible furnaces are particularly suitable for jobbing shops where frequent alloy changes are required.
7. Electric Resistance Heated "Globar" Aluminum Wet Bath Reverb Furnace
In the permanent mold casting industry, gas fired dry hearth furnaces and gas fired or electric resistance heated crucible furnaces are preferred.
For cases where metal quality is critical or for electric motor rotor casting suppliers, the electric resistance heated "globar" aluminum wet bath reverb furnace is the predominant choice due to its high energy efficiency, superior metal quality, and low melt losses.
