Graphite Launder

Features & Benefits

• High thermal conductivity: Graphite has high thermal conductivity, which allows for efficient heat transfer and helps maintain the desired temperature of the molten aluminum during transportation.
• Good thermal shock resistance: Graphite launders can withstand rapid temperature changes without cracking or damage, ensuring reliable and continuous operation.
• Chemical inertness: Graphite is chemically inert and does not react with molten aluminum or its alloys. This property prevents contamination and ensures the purity of the aluminum being transported.
• Excellent resistance to corrosion: Graphite is highly resistant to corrosion from molten aluminum, which can contain impurities and reactive elements. This resistance extends the lifespan of the graphite launder.
• High mechanical strength: Graphite launders have good mechanical strength and can withstand the weight of the molten aluminum and the associated stresses during casting operations.
• Easy to shape and customize: Graphite material can be easily machined and shaped into various launder configurations to suit specific casting processes and requirements.
• Long lifespan: Graphite launders have a relatively long operational lifespan due to the high durability and thermal stability of graphite material. They can withstand repeated use and exposure to high temperatures.
• Energy-efficient: Graphite launders have low thermal mass, which means they require less energy to heat up and maintain the desired temperature compared to other refractory materials.

Markets & Applications

• Aluminum smelters: Graphite launders are used to transport molten aluminum from the smelting furnace to the casting area.
• Continuous casting: Graphite launders are utilized in continuous casting processes, where molten aluminum is continuously poured into molds to produce long sections such as rods, bars, and profiles.
• Die casting: Graphite launders are used in die casting operations, where molten aluminum is injected into metal molds to create intricate shapes and components.
• Gravity casting: Graphite launders facilitate the controlled pouring and distribution of molten aluminum in gravity casting processes, ensuring consistent filling of molds.
• Foundries: Graphite launders are employed in various foundry applications where molten aluminum is transferred and distributed, such as sand casting, investment casting, and centrifugal casting.
