Introduction of Aluminum Trough & Launder

Trough/launder systems carry molten aluminum from one location to another location. The system has two functions: conveying and insulation. The system usually includes surface refractories, spare insulation materials, steel structures, gates, and other high-temperature equipment such as thermocouples and gaskets. They are most often used to transport molten aluminum from a melting furnace to a holding furnace, from a holding furnace to a casting station or to carry molten aluminum to inline degassing and filtration systems. Effective trough systems help maintain metal temperature and prevent oxide buildup.

The lining of the trough & launder system is made of high-quality medium-density fused silica refractory and pre-sintered at 800°C before assembly. It has high aluminum resistance, low thermal conductivity, low shrinkage, and high strength. Xinhongji Refractory's application experts and technical department work with customers to determine the optimal design and materials for your trough systems. We also have on-site combustion capabilities up to 2450°F. Our molten aluminum launder and trough can be designed for low thermal expansion, low thermal conductivity, wear resistance, or non-wetting characteristics.

Advantages of Aluminum Trough & Launder

1. Good insulation performance, reasonable design, and long service life.

2. It is integrally molded with noble molten material and has high dimensional accuracy.

3. Corrosion-resistant, insulating, thermal-shock resistant, high strength, lower thermal diffusivity.

4. The inner liner has strong corrosion resistance to aluminum, zinc, and magnesium alloys.

5. It enhances the use effect of molten metal transfer equipment and strengthens the service life of special alloys.

6. The temperature drop of the metal liquid during use is 2 °C per meter, resistant to erosion, heat shock, and smooth surface.

We can provide a number of solutions with engineering and manufacturing to design and implement a variety of trough systems. Products include refractory materials, precast shapes, backup insulation, heated trough covers, and coatings.

Advantages of Insulation Trough and Launder System

1. The aluminum liquid movable launder has good heat preservation performance, and the temperature can be reduced to within 1℃ per meter.

2. It does not react with molten aluminum at working temperature, has low density, good non-stick properties of aluminum, and flexible continuous casting and rolling.

3. The movable flow channel of molten aluminum is integrally formed with high silicon melt material, with high dimensional accuracy.

4. The movable trough of molten aluminum can be used repeatedly or repeatedly, and the surface is smooth.

5. Good anti-sticking aluminum performance, easy to remove the condensate shell.

6. Anti-scouring, strong and durable.

7. Ultra-stable volume, resistance to cold and heat shock.

8. Reduce the maintenance of the joints between the sections and save costs.
