Copper tube in the steel industry

Copper tubes are a key component in continuous steel casting molds, playing an important role in heat transfer and initial shaping of the steel billet. These tubes are made of high-purity copper and are usually coated with chromium or nickel to resist wear, corrosion, and high temperatures.

Due to the high price of imported copper tubes, many steelmaking units are refurbishing and re-plating used tubes instead of purchasing new ones. This method not only reduces costs, but also saves foreign exchange and increases productivity in production lines.

Copper tubes in continuous steel casting molds: A vital role in the steelmaking industry

Recycling copper tubes is a sustainable and environmentally friendly solution that prevents the production of metal waste and conserves natural resources.

🔍 چرا تیوب مسی اهمیت دارد؟

  • Rapid heat transfer: Copper, due to its high thermal conductivity, causes the molten steel to solidify uniformly.

  • Increasing the quality of the final product: Using copper tubes with appropriate coating reduces surface cracks and structural defects.

  • Reduced energy consumption: Better copper tube performance reduces casting time and saves energy.

Given the importance of copper tubes in the continuous casting process, the correct choice of surface coating type and their maintenance method has a direct impact on the quality of steel ingots and the reduction of production stops. The use of modern technologies such as nanocomposite plating and periodic monitoring of tubes can increase their useful life by several times. These measures will not only increase the productivity of casting lines, but also reduce maintenance costs and increase the competitiveness of steel production units in the long run.
