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
