Trends in Continuous Casting Mould Technology: A Key Factor for High-Quality Steel Production

In modern steelmaking, continuous casting has become the dominant process for billet and slab production. As a core component of the continuous casting machine, the mould plays a critical role in determining surface quality, internal structure, and overall casting stability.

With increasing demands for higher efficiency, lower energy consumption, and improved yield, continuous casting mould copper tubes and assemblies have seen continuous upgrades in material selection, structural design, and manufacturing accuracy. High-purity copper materials are widely used due to their excellent thermal conductivity, enabling rapid and uniform heat transfer and effective control of initial shell formation.

To meet the requirements of different steel grades and casting conditions, mould copper tubes are continuously optimized in terms of inner cavity design, taper configuration, and surface coatings. Proper taper design helps compensate for solidification shrinkage, reducing the risk of cracks and sticking, while advanced coatings significantly improve wear resistance and service life.

In addition, the performance of the mould assembly—such as structural stability, uniform cooling water distribution, and precise assembly—is essential for ensuring smooth and reliable casting operations. Through refined design and strict quality control, mould systems can maintain stable performance even under high casting speeds and demanding operating conditions.

Looking ahead, as the steel industry moves toward intelligent and refined manufacturing, continuous casting mould products will place greater emphasis on system compatibility and long-term operational stability, supporting steel producers in achieving high-quality and sustainable production.
