Best Crucible For Melting Aluminum

Features

High temperature resistance: The molten aluminum crucible can work at temperatures up to 1700℃ for a long time without deformation or damage.

Corrosion Resistant: Made of high-quality materials such as silicon carbide, graphite or ceramics, it effectively resists corrosion from aluminum and other chemicals.

High thermal conductivity: It has excellent thermal conductivity and can heat aluminum liquid quickly and evenly to improve production efficiency.

Strong wear resistance: The surface is specially treated to have strong wear resistance and extend the service life.

Good stability: Maintain good mechanical strength and stability in high temperature environments to ensure the safety and reliability of the production process.

Instructions for use

1. Preparations before first use

Inspect the crucible: Before first use, carefully inspect the crucible for any cracks, damage, or defects.

Preheating treatment: The crucible needs to be preheated before formal use.  Place the crucible into the furnace, gradually raise the temperature to 200°C, maintain it for 1 hour, and then increase the temperature by 150°C every hour until the operating temperature is reached.  This process helps remove moisture from the crucible and prevents cracking due to sudden changes in temperature.

2. Aluminum melting steps

Loading: Put the aluminum raw materials evenly into the crucible to avoid overloading, overflow or uneven heating.

heating:

Use an electric or gas stove for heating and avoid direct heating with an open flame.

Control the heating speed, gradually increase the temperature, and avoid sudden changes in temperature.

The aluminum liquid should be stirred frequently during heating to ensure uniform heating.

Melting: After the aluminum raw material is completely melted, the high temperature is maintained for a certain period of time to ensure that the impurities in the aluminum liquid are fully precipitated.

Refining treatment: Add an appropriate amount of refining agent to the aluminum liquid as needed to remove impurities and improve the quality of the aluminum liquid.

3. Post-processing of molten aluminum

Pouring: Use special tools to pour out the aluminum liquid in the crucible, pay attention to safety and avoid burns.

Crucible cleaning: After each use, clean the remaining aluminum liquid and impurities in the crucible in time to keep the crucible clean.

Maintenance: Check the crucible regularly. If cracks or wear are found, replace them in time.  Also, preheat the crucible regularly to extend its service life.

Precautions

Operation safety: When using molten aluminum crucible, please wear protective gloves, goggles and other protective equipment to avoid burns from high-temperature aluminum liquid.

Temperature control: Strictly control the heating temperature and speed to avoid damage to the crucible caused by sudden changes in temperature.

Environmental cleanliness: Keep the operating environment clean and prevent the crucible from being hit or falling from high places.

Storage conditions: Store the crucible in a dry, well-ventilated environment to prevent moisture.
