FurnStar is an extension of the industry-leading submerged-arc furnace controller Minstral, which is installed on over 100 furnaces in 9 countries. FurnStar extends Minstral’s capabilities beyond controlling electrode penetration and power input to the furnace, to include a number of submerged-arc electrode management and furnace control tools.

The FurnStar suite of control modules, a product from Mintek, utilises advanced process control to overcome design-related limitations and maximise furnace performance.  This modular approach ensures the design of a customised solution, specific to the objectives of each plant.
Furthermore, this approach allows for phased implementations which are useful both in assessing the benefit of the system, and in allowing plant personnel to be introduced gradually to any changes in operation (Change-Management).


  • Improved power input (MWh).
  • Lower specific energy consumption (MWh/ton).
  • Improved load factor.
  • Reduced electrode consumption.
  • Reduced electrode breakages. • Improved recovery
