Maximise Performance in Hot Dip Galvanising Lines with Nilcra® Ceramic Sink Roll Bushes

Engineered for Extreme Environments

In the demanding world of hot dip galvanising, durability and precision are critical. As steel coil production accelerates, the need for resilient, wear-resistant materials becomes more urgent. At the heart of this challenge lies the submerged sink roll bearings — essential for maintaining continuous, high-quality output.

Morgan Technical Ceramics delivers a proven solution with its advanced Nilcra^® Ceramic Sink Roll Bushes, crafted from Sintered Silicon Nitride (Si₃N₄) and Zirconia (Mg-PSZ). These materials are engineered to withstand the harshest conditions — from elevated temperatures and thermal shock to intense mechanical stress.

Why Choose Nilcra^® Ceramic Bushes?

• Reduced Downtime
  Ceramic bushes last 2-4 times longer than traditional Stellite or stainless-steel alloys, significantly reducing maintenance frequency and production interruptions.
• Superior Strip Quality
  Lower friction and wear rates mean less vibration and more consistent strip movement, resulting in a smoother, more uniform zinc coating.
• Increased Productivity
  Ceramic components enable higher line speeds, boosting throughput without compromising quality.
• Proven Performance
  Manufacturers using Nilcra^® report:
  
  • Enhanced surface finish
  • Improved zinc coating consistency
  • Higher process efficiency
  • Greater yield and reduced waste

Material Properties

Ceramics (MgO-ZrO₂ and SiAlON) show:

• Excellent corrosion resistance
• Minimal wear when paired with softer metals
• Chemically inert to Zinc-Aluminium
• Last 2-4x longer in lifetime and use
• Less susceptible to unstable operation

Magnesia Stabilised Zirconia (Nilcra® Zirconia) is suitable for Zinc only lines (Zirconia can be wetted by Aluminium)
Nilcra® SiAlON is suitable for Zinc-Aluminium lines
