Industries We Support

01

Iron & Steel

Steel production operates under extreme thermal loads, aggressive slag conditions, and continuous operational pressure - where refractory performance and process stability directly impact output, cost, and downtime.

How we support:

  • Optimisation of electric arc furnace (EAF) and ladle thermal performance
  • Refractory lining design aligned with slag chemistry and operating cycles
  • Analysis of heat losses and thermal inefficiencies across melting stages
  • Improvement of tapping consistency and temperature control
  • Support for tundish and continuous casting refractory performance

Typical impact:

  • Reduction of refractory wear rates by 12-22% in high-stress zones
  • Extension of ladle campaign life by 15-30 heats per cycle
  • Decrease in electrode and energy consumption by 3-8%
  • Reduction in unplanned stoppages linked to lining failure by up to 20%
  • Improved temperature consistency at tapping within a +-5-10C range

02

Cement

Cement production relies on continuous kiln operation under extreme thermal, chemical, and mechanical stress - where refractory performance, fuel strategy, and process stability directly influence output and maintenance cycles.

How we support:

  • Kiln refractory configuration aligned with coating behaviour and fuel mix
  • Analysis of heat transfer efficiency and burning zone performance
  • Support for alternative fuel integration and its impact on refractory wear
  • Identification of instability drivers (ring formation, coating loss, hot spots)
  • Optimisation of shutdown planning and maintenance intervals

Typical impact:

  • Extension of kiln campaign duration by 2-6 months
  • Reduction in specific heat consumption by 50-120 kcal/kg clinker
  • Decrease in unscheduled kiln stops by up to 15%
  • Reduction in refractory replacement frequency in critical zones by 10-18%

03

Glass & Ceramics

Glass and ceramics production demand precise thermal control, stable furnace conditions, and material integrity - where even minor inconsistencies can affect product quality and furnace longevity.

How we support:

  • Optimisation of temperature distribution across melting and refining zones
  • Selection of refractory materials resistant to glass corrosion and volatilisation
  • Identification of causes of thermal imbalance and local overheating
  • Support for furnace campaign planning and rebuild strategies
  • Evaluation of batch and thermal interaction affecting furnace conditions

Typical impact:

  • Reduction in rejected output linked to thermal defects by 6-14%
  • Stabilisation of crown temperature fluctuations within +-3-7C
  • Extension of furnace campaign duration by 1-3 years
  • Reduction in local refractory corrosion rates by up to 20%

04

Aluminium & Non-Ferrous Metals

In aluminium and non-ferrous processing, thermal stability, contamination control, and refractory compatibility directly influence metal quality and yield.

How we support:

  • Evaluation of refractory interaction with molten metal and slags
  • Optimisation of insulation systems to maintain stable holding temperature
  • Reduction of metal losses during melting, transfer, and holding
  • Identification of contamination sources linked to refractory degradation
  • Support for furnace lining strategies in aggressive environments

Typical impact:

  • Reduction in metal loss during holding and transfer by 2-5%
