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
