Coating prolongs mold life.
• Main reasons for coating:
- Prolonging Mold life
(better wear resistance)
- Improving slab quality
(avoiding star cracks)
• Side effects of coating:
- Reduced heat transfer
(approx. 1.5 %/mm Ni)
- Higher wall temperatures
(approx. 15°C/mm Ni)

CSN offers technical assistance as well as mold plates tailored to
your specific needs.
How can we optimize the lifetime of your molds?
Parameters
to be considered
• Chemistry of cast steel
• Mold flux
• Cooling conditions
(water quality, flow rate, velocity)
• Casting speed
• Adjustment of strand guide
• Mold taper
• Adjustment of oscillating unit
• Wall thickness
• Width changes
• …
Therefore, we have to carefully
look at each individual case for fine tuning.
