Silicon metal is an essential element in the production of various electronic devices and alloys. It is largely used in the manufacturing of semiconductors, aluminum alloys, and solar cells, etc.
The two most plentiful elements oxygen and silicon combine to form SiO2, which is found all over the world and is the preliminary ingredient for the formation of silicon metal.
The refining process is one of the essential steps in the production of silicon metal, which demands high-temperature conditions and non-ferrous materials for blowing gases. Hence, in this situation our Aluminum Lance Pipes comes to the rescue.
Today, in this content, we shall be going to discuss the application and usage of the Aluminum Lance Pipes.
Aluminum Lance: Application and Necessity for Silicon Metal Production

Aluminum Lance Pipes are well known for their advanced thermal conductivity, making them an ideal pick for silicon metal production. These lances help in the controlled distribution of the flow of gases into the furnace, which results in an eminent product. Furthermore, their corrosion-resistant and durable properties make them an economical choice in the long run. Hence, the use of Aluminum Lance Pipes in silicon metal production is a wise decision that ensures a high grade of pure silicon metal in the refining process.
Introduction: Aluminum Lance Pipe
The Ceramic Coated Lance Pipe (CC) is generally used in the making of silicon metal. However, since iron (Fe) becomes impure when it dissolves into silicon metal, therefore the CC lances cannot be used in the effectiveness for production of pure silicon metal. Thus, the aluminum lance pipe is used for better manufacturing of pure silicon metal.
Since the melting point (The melting point of Aluminum is around 660℃) of aluminum is lower than that of iron, so aluminum lances cannot serve alone as lance pipes.
Therefore, our Aluminum Lance Pipes (AL), are produced from an aluminum pipe with a layer of thick refractory ceramic coating, applied on surface of the aluminum pipe by a special method which develops and supplies products appropriate for silicon metal production. The double ceramic coating is done to ensure the durability for higher performance.
Aluminum Lance Pipe: Connections
The Aluminum Lances are available in various sizes. Please get in touch with us to know about our current sizes for the Aluminum Lances.
There are 2 types of connection available for Aluminum Lance Pipe: Sockets and Press-Coupling.
Aluminum Sockets connecting for Aluminum Lance Pipes
Aluminum Press Coupling for connecting Aluminum Lance Pipes
Aluminum Lance Pipe: Application
Silicon metal is treated to produce solar panels by using aluminum lance pipes. As the main ingredient to manufacture the solar panels is silicon metals, we have produced the aluminum lances in addition to normal oxygen lances to help in the production of solar panels.

Aluminum Lance Pipe: Usage for Silicon Metal Production
Aluminum Lance Pipes are known for their advanced thermal conductivity, making them a smart choice for production of silicon metal. They help in delivering a controlled flow of reactants and coolant gases into the furnace, resulting in a higher-quality product. The use of Aluminum Lance Pipes in silicon metal production is a wise choice that ensures a more efficient and effective refining process. Also, their corrosion resistant properties and durability make them an economical choice in the long run.
Real time performance with Aluminum Lance Pipe
The findings from our real time performance with Aluminum Lance Pipe are as below:
Capacity of silicon metal furnace: 4-5 tons per heat.
Smelting temperature: around 1,650℃ – 1,800℃.
Oxygen blowing time in normal circumstances: a 5.5m lance would take approx. 3 – 7 minutes/ heat.
Oxygen blowing time in competent working conditions: in a 3m lance, it takes approx. 2 – 3 minutes/ heat to absorb 1.5m lance.
Average consumption of Ceramic Coated Aluminum Pipe: in a 1/2″ x 5.5m pipe, it takes either 1/3rd part of the pipe/heat or 1/2 of pipe/ heat or 1 pipe/heat depending on the usage control of the operator.
Conclusion
It is important to know exactly what kind of lance pipe should be used for each stage of production in the aluminum firms in order to increase its productivity and be economical at the same time. Here, we tried to explain the general uses of Aluminum Lance Pipe, and we hope that now it will be easier for our customers to understand the function of the Aluminum Lance in the production of Silicon Metal.
