Melting copper requires precise temperature control.
The melting point of copper is approximately 1085°C (1985°F).
To melt copper, a furnace must be capable of reaching and maintaining this temperature.
4 Key Factors to Consider
1. Types of Furnaces Used
In industrial settings, various types of furnaces are used, including three-zone furnaces and medium frequency induction furnaces.
2. Three-Zone Furnace Configuration
In a three-zone furnace, the first two zones are set below the melting point of copper to pre-heat the materials.
The third zone is set to a temperature just 10-15°C above the melting point of copper, which is around 1095-1100°C (1993-2012°F).
This configuration allows for precise control over the melting process.
It minimizes the time the copper spends at its melting point.
It facilitates better control over the flow of the molten copper.
3. Medium Frequency Induction Furnaces
Medium frequency induction furnaces are also commonly used for melting copper and its alloys.
These furnaces can reach temperatures close to 2000°C (3632°F), which is well above the melting point of copper.
The induction heating method, based on electromagnetic induction, generates heat directly in the metal.
This makes the melting process efficient and controllable.
When using medium frequency induction furnaces to melt copper alloys, it is important to follow specific operational procedures.
These include the materials feeding principle and the melting sequence.
This ensures the quality and efficiency of the melting process.
4. Temperature Requirements
Overall, to melt copper effectively, a furnace must be capable of reaching at least 1085°C (1985°F).
The furnace should be designed or configured to handle the specific requirements of melting copper.
This includes the use of three-zone or induction heating technologies.
