The Stein Digit@l Furnace® technology is applicable for all types of furnaces producing semi-finished products, as follows:

  • Hot rolled coil for automotive quality (carbon steel) and for other different steel grades (stainless or electrical steel)
  • Heavy plate for different applications such as building, bridges,pressure vessels, tubes, pipes and shipbuilding
  • Rails for high speed trains, sections, profiles for building applications, and wire rods

Stein Digit@l Furnace®

Fives has developed and industrially proven a new innovative technology which has been incorporated into the reheating furnace design under the brand name Stein Digit@l Furnace®

  • Straight Line Furnace Casing: easy maintenance, and sustainable furnace lifetime With 100% lateral burners in the top zones, meaning that roof burners can be avoided, which results in less maintenance.
  • Independent lateral AdvanTek® burners: flexibility and quality. Each pair of burners is an independent control zone, hence improved heating control and product uniformity.
  • Individual on/off control: energy saving. Very Low consumption over the full production range and Ultra Low NOx emissions
