APROCS, Advanced Property Control System

Characteristics of advanced wire rod mills

Production speeds up to 120 m/s
Utilization factor up to 90% and more
Yield of material over 96%
Good tolerances and minimum surface scratching to achieve best prices in the markets
Temperature control system throughout the mill to achieve repeatable and uniform material properties:
- Rolling within closed temperature ranges meeting the particular material demands
- Low temperature rolling
- Controlled cooling process used as in-line heat treatment or for "pre-adjustment" of material properties
- Low labour cost due to high degree of automation
- Extensive program system for both the rolling process and subsequent rod treatment
- Developed and improved continuously, including the experience and expertise gained from many rolling mills delivered by MWE
- An effective tool to save costs in downstream processes and achieve an optimal product structure and specific physical properties

Adjustable speed to influence package compactness by varying ring overlapping patterns
Steps within the conveyor and provision for change of roller groups speed to change overlap position
Suitable for retarded and accelerated cooling
Consisting of three sections:
- Ring laying section
- Secondary cooling train for controlled cooling
- Delivery section to reforming tub

Maintain the desired temperature field by regulating the water pressure
Temperature controlled rolling possible
Improved grain size (fine) of rolled material
Quick-acting valves for higher speeds and small-diameter rod to shut off the water flow while the rod head end enters the cooling pipes
Cooling line also suitable for other products
High strength values:
- Yield point: 500 N/mm²
- Tensile strength: 560 N/mm²
- Elongation percentage grade: 12 %
other data
