The High Casting Speed Copper Mould Tube for Mild Steel Billet is a critical component in the continuous casting process, designed to solidify liquid metal into billets efficiently. These tubes are situated at the heart of the continuous casting machine and play a vital role in determining the quality and productivity of the steel billets produced.

1. Material Composition:
• The tubes are made from high-quality copper alloys such as Cu-Ag (copper-silver), which offer superior thermal conductivity and mechanical strength. This material choice ensures efficient heat transfer and longer service life.
2. Taper Design:
• The taper of the copper tube is optimized to enhance the casting speed and reduce the risk of breakouts. Different tapers are available, including single taper, multi-taper, parabolic, convex, and diamond taper. The selection of the appropriate taper is crucial for achieving higher casting speeds and improving the quality of the billets.
3. Coating Technology:
• Advanced electroplating technology is used to apply a hard chromium or composite coating on the inner surface of the copper tube. This coating not only increases the wear resistance but also enhances the bonding strength between the coating and the copper substrate, thereby extending the service life of the tube.
4. Precision Manufacturing:
• The manufacturing process includes melting & casting, hot extrusion/forging, cold drawing, tapering, machining, electroplating, and final inspection. Each step is carefully controlled to ensure the highest quality and precision in the final product.
5. Heat Transfer Efficiency:
• The design of the copper mould tube ensures uniform and intensive heat flux, which is essential for high-speed casting. The tube's ability to efficiently transfer heat away from the molten steel helps in solidifying the billet quickly and uniformly.
6. Service Life:
• The combination of high-quality materials, advanced coating technology, and precision manufacturing results in an extra-long service life. This reduces the frequency of replacements and maintenance, thereby increasing the overall efficiency of the continuous casting process.
  
  

Application:

The High Casting Speed Copper Mould Tube is used in continuous casting machines for the production of mild steel billets. It is designed to withstand the high thermal loads and mechanical stresses associated with high-speed casting operations. The tube's ability to efficiently solidify the liquid metal and maintain a stable casting process is crucial for producing high-quality steel billets with minimal defects.

Benefits:

• Increased Casting Speed: The optimized design and material properties allow for casting speeds of over 4 meters per minute, significantly enhancing productivity.
• Improved Billet Quality: Uniform heat transfer and the reduced risk of breakouts contribute to the production of high-quality steel billets with fewer defects.
• Extended Service Life: The advanced coating and manufacturing processes ensure that the copper mould tubes have a longer service life, reducing downtime and maintenance costs.
