Inner Taper Precision: The Secret to Eliminating Billet Surface Cracks
Surface cracks on steel billets are often caused by poor contact between the copper tube and the cooling shell. As shown in our internal view (see photo), CYKC Group’s copper mould tubes feature a mirror-like finish and high-precision internal geometry.
We use advanced CNC machining to ensure that the inner taper perfectly matches the shrinkage profile of the molten steel. This ensures:
Uniform Cooling: Eliminates hotspots and corner cracks.
Higher Casting Speed: Increases production yield without compromising safety.
Longevity: Specialized coating prevents copper pickup and thermal fatigue.
Whether you need Round, Square, or Rectangular profiles, CYKC Group provides customized solutions tailored to your CCM’s specific cooling parameters.
