The X-Roll® Cooling Concept combines several modules and systems in a performance package applicable in greenfield as well as in brownfield plants. Of course, the modules can also be selected individually. The most capable modules in this package are:

Module Main advantages
Transfer bar cooling (roughing mill exit area)
  • Controlled water application over transfer bar width and length in order to improve the rolling process in the finishing mill
  • Equalized temperature profile
  • Improved strip surface
  • Higher production by lower oscillation times

HIBOX® system
(roughing mill exit area)

  • Energy savings due to reduction of the furnace temperature
  • Better temperature homogeneity over width and length
  • More uniform forces and torques in the finishing mill
  • Four times longer service lifetime than conventional design
Modular laminar strip cooling system
(finishing mill exit area)
  • Flexible adjustable cooling rates
  • High accuracy in achieving the required process temperatures
  • Cost saving by reduction of alloying elements
  • Enlarged product mix

New edge masking
(finishing mill exit area)

  • Improved strip flatness in cooling sections (especially for thin strips)
  • Equalized strip temperature distribution and therefore avoidance of asymmetric temperature profiles
  • Separate movable and maintenance-friendly edge-masking shields

X-Pact® Cooling Section Control
(cooling section)

  • Cooling strategies for a wide range of hot rolled products
  • Very high accuracy for repeatable material properties
  • Designed for all different mechanical designs
  • Exact control of coiling temperature
  • Adaptable for next generation steel grades

X-Pact® Integrated Temperature Model
(complete mill)

  • Combining all processing steps from the furnace to the downcoiler to form a higher-order temperature model
  • All processing steps interact and subordinate themselves to the best overall result
  • Adjustment of material properties with an optimized temperature profile
  • Stable, highest production with homogeneous work load in each production step
