CERAMIC CORES

Nutec Bickley has extensive experience designing and manufacturing
tunnel kilns and shuttle kilns for the Ceramic Core industry.

Our kilns use the latest combustion and control technology to fire cores
with the best temperature uniformity and atmosphere conditions to ensure
consistent product which requires minimal post fire machining.

Ceramic Cores are often complex shapes made from High Purity, stable Ceramic materials that are set within a mould when a product is cast to create interior holes and pathways in the metal after casting and core removal. For example, Turbine blades use ceramic cores to create internal cooling air paths that prevent a blade from melting at super high temperatures.

With over 45 years’ experience, Nutec Bickley has demonstrated a knowledge and experience firing Ceramic Cores. As most Ceramic Core bodies contain organic binders to allow manufacture, they need careful firing during their burnout, so our kilns are designed with that in mind. The kilns are often fitted with thermal oxidizers or Post exhaust cleaning systems to protect the environment. Nutec Bickley have supplied many kilns around the world for firing Ceramic Cores.

FEATURES

FEATURES

Nutec Bickley’s flexibility in design offers the following features:

  • The best Control system offered in the market
  • Excellent Temperature Uniformity
  • Power Failure Protection System (PFPS) maintains the kiln alight up to 1 minute in case of a power outage
  • Nutec Bickley’s Kilns are lined with either brick, or their patented Jointless® Fibre System
  • Energy recovery systems to ensure the lowest fuel consumption
  • SCADA systems for ease of operation and product quality management.
  • Integrated Car Handling Systems

PROCESSES

  • Firing/Sintering: High temperature heating is used to create strong chemical and ceramic bonds. If temperatures are very uniform then the fired product will be very close to dimensional tolerances and minimal final grinding will be required.
  • Burnout/Debindering/Debinding: During this low temperature process the organic binders and lubricants are burnt out of the body. Shrinkage can occur during this process so the temperature increase must be carefully controlled and each part of the core must be at the same temperature to reduce mechanical stresses. If the organics are removed too quickly or with the wrong kiln atmospheres then the product can be damaged.
