Introduction
Copper has long been used as a material for heat exchange due to its excellent thermal conductivity. In order to improve the copper’s working efficiency, Japanese high furnace has developed a new technology – Cooling wall made of copper. The coolant oxide film produced by this new technology can insure working efficiency, save energy and improve the operational reliability.
The Working Environment
The surface of high-temperature metal materials, such as steel and copper, are easily corroded by high temperature and atmosphere, therefore it is important to protect them from corrosion. In order to prevent corrosion of the metal surface, high furnace developed a new surface treatment: a high-temperature, corrosion-resistant oxide film. Unlike traditional methods, this process does not require an expensive coating, and the oxide film can be applied to the metal surface at high temperatures. This film helps to prevent the surface of the metal from corrosion and allows the metal to function at high temperatures, prolonging its working life.
The Technology of Copper Cooling Wall
The copper cooling wall is composed of a thin layer of copper and a thin protective layer of oxide, which is applied to the copper surface. The oxide film is formed by flowing nitrous oxide into the hot copper surface, which forms a layer of oxide on the copper surface. This oxide film not only protects the copper surface from corrosion, but also helps to reduce the temperature of the copper surface when the high furnace is in operation.
The Benefits of Copper Cooling Wall
The thin protective layer of oxide provides the copper surface with excellent heat and corrosion resistant properties, meaning that it can handle higher temperatures and longer working times. The result is faster and more efficient heat transfers from the furnace to the cooling chamber, which improves the furnace’s overall efficiency and performance. In addition, the thin protective layer on the copper surface prevents the formation of slag, which can corrode and damage the interior components of the furnace, leading to time and money wasted in maintenance repairs.
Conclusion
In conclusion, the new copper cooling wall technology developed by Japanese high furnace is an excellent way to protect the furnace from corrosion and improve its working efficiency. The protective layer of oxide serves to reduce the temperature of the copper surface, improving the overall efficiency of the furnace and helping to maintain its working life. Overall, this technology is an important step forward in creating a more energy-efficient furnace, and it is sure to become an important part of modern high-temperature metals production processes.
