Ceramic Launder And Trough For Conveying Molten Aluminum

Aluminum silicate ceramic launder and trough are widely used in the casting industry on a variety of specific casting equipment, which usually involves the transport and distribution of high-temperature molten metals. It is suitable for conveying and distributing metal liquid on a variety of specific casting equipment. These equipment include, but are not limited to, between aluminum smelting furnace and casting machine, casting platform and outside furnace degassing and filtration system, continuous casting machine, gravity casting machine and low pressure casting machine, and special alloy casting equipment.

1. Between aluminum melting furnace and casting machine

Aluminum silicate ceramic launder and trough is often used to connect aluminum melting furnace and casting machine to ensure that aluminum liquid from the aluminum melting furnace to the casting machine smoothly and stably for casting. In this process, the thermal insulation performance of the aluminum silicate ceramic launder and the corrosion resistance of the aluminum liquid are crucial, which can keep the temperature of the aluminum liquid stable, prevent heat loss and chemical reaction between the aluminum liquid and the trough material.

2. Casting platform and furnace outside the gas removal and filtration system

In the process of aluminum alloy casting, the gas removal and filtration system outside the furnace are the key links to improve the quality of the casting. The aluminum silicate ceramic fiber launder and trough is used to connect the casting platform to these systems, ensuring that the degassed and filtered aluminum liquid can be smoothly transported to the next casting stage. This application requires the ceramic launder to have precise diverting capacity and stable conveying performance to ensure the purity and fluidity of the liquid aluminum.

3. Continuous casting machine

In the continuous casting process, the aluminum silicate ceramic fiber launder is the key component connecting the melting equipment and the mold. It can continuously transport the metal liquid to the mold to form a continuous casting blank. This application puts forward extremely high requirements for the high temperature resistance, erosion resistance and stability of the chute, and aluminum silicate ceramic fiber materials just meet these needs.

4. Gravity casting machine and low pressure casting machine

In gravity casting and low pressure casting processes, aluminum silicate ceramic trough are used to distribute and transport metal liquids. These casting processes require liquid metal to fill the mold slowly at low pressure, so the ceramic launder needs to have the ability to precisely control flow and temperature. The excellent properties of the aluminum silicate ceramic launder make it an ideal choice for these casting equipment.

5. Special alloy casting equipment 

For the casting process of some special alloys, such as super alloys, corrosion resistant alloys, etc., casting equipment has more stringent requirements for the transportation and distribution of metal liquids. The aluminum silicate launder can withstand the erosion and erosion of molten metal at high temperature to ensure the purity and stability of the metal liquid in the transportation process. Therefore, in special alloy casting equipment, aluminum silicate ceramic launder has also been widely used.

First, excellent thermal insulation performance

High efficiency insulation: aluminum silicate ceramic launder trough is made of high grade aluminum silicate ceramic fiber and other formulations through vacuum molding, with excellent insulation performance, can effectively reduce the heat loss of aluminum liquid in the flow process, keep the temperature of aluminum liquid stable.

Low temperature drop: In the process of using, aluminum silicate ceramic launder and trough can achieve temperature drop control per meter in a low range (such as 1-2 ° C per meter), which is particularly important for aluminum processing that requires precise temperature control.

Second, excellent durability and stability

High strength erosion resistance: the ceramic launder lining has high strength, can withstand the erosion of aluminum liquid, and extend the service life.

Good thermal shock resistance: aluminum silicate ceramic fiber material has excellent thermal stability, can withstand the thermal stress caused by temperature changes, and is not easy to fracture.

Strong corrosion resistance: It has good corrosion resistance to aluminum, zinc, magnesium alloy and other molten metals, which enhances the use effect of molten metal transfer equipment.

Third, good non-stick aluminum performance

Smooth surface: The surface of the aluminum silicate ceramic trough covers is smooth, not easy to stick aluminum, reducing the cleaning workload and the risk of aluminum liquid pollution.

Special coating treatment: Some aluminum silicate launder also uses special coating treatment (such as aluminum titanate coating) to further improve the corrosion resistance of aluminum liquid and extend the service life.

4. Other advantages

Excellent electrical performance: aluminum silicate trough has good electrical performance and high temperature insulation performance, can not burn in the open flame, no carbonization, and will not release toxic gases.

Moisture-proof and earthquake-proof: It has good moisture-proof performance and earthquake-resistant and compressive performance to ensure that it can still work stably in harsh working environment.

Highly customizable: customized production can be carried out according to customer needs to meet different occasions and process requirements.

Aluminum silicate ceramic launder and trough is mainly used in aluminum processing and metallurgy industry, especially in the need for efficient thermal insulation, erosion resistance, thermal shock resistance and corrosion resistance to molten metal. In aluminum processing, it is used for the distribution and transmission of aluminum liquid to keep the temperature of aluminum liquid stable; In the metallurgical industry, it is used as a thermal insulation material for various stoves. In addition, aluminum silicate through is also suitable for processes with high metal purity requirements because of its non-stick aluminum and pollution-free characteristics.
