In the continuous casting process of the steel industry, copper mold tubes play a crucial role. As the core component of the mold, their performance directly affects the quality of the continuously cast billet, production efficiency, and equipment lifespan.
These specially designed copper tubes, due to their excellent thermal conductivity and certain strength, are ideal materials for the inner wall of the mold. During continuous casting, high-temperature molten steel cools and initially solidifies inside the copper mold tubes. The efficient thermal conductivity of the copper tubes ensures rapid and uniform heat dissipation of the molten steel, forming a sufficiently thick and uniform billet shell, which is crucial for preventing defects such as run-through and reducing surface cracks. Furthermore, high-quality copper mold tubes typically undergo special plating treatments (such as chrome plating) to enhance their surface hardness, wear resistance, and corrosion resistance, thereby significantly extending replacement cycles and reducing maintenance costs.
Therefore, selecting high-performance, high-reliability copper mold tubes is a key step for steel companies to ensure smooth continuous casting operations, improve billet quality, and achieve cost reduction and efficiency improvement. It is the "first checkpoint" connecting molten steel at high temperature with the solid billet shell, and its importance is self-evident.
