Considerations For Mold Copper Plates

During operation, mold copper plates require regular inspection and maintenance to ensure consistent performance. Common forms of damage include surface wear, thermal fatigue cracking, and deformation. Wear primarily results from friction between the cast strand and the copper plate; this can be mitigated through surface coatings or lubrication. Thermal fatigue cracking is caused by repeated thermal cycling and can be alleviated by optimizing cooling systems and material selection. Deformation is associated with stress relaxation at high temperatures, which can be effectively suppressed through proper design and the use of appropriate materials. Maintenance measures-such as surface repair, dimensional correction, and re-coating-are essential for extending the service life of the copper plates.
