ALUMINUM CROP OPTIMIZATION SYSTEM

Automated End-Crop Optimization for Aluminum Hot Strip Mills

 

ALUMIVIEW ACOS C865C test

The ALUMIVIEW Crop Optimization System (ACOS) C865C is a non-contact optoelectronic system that automates end-crop optimization in aluminum hot strip mills, using real-time image processing to detect "alligator" defects and calculate the optimal crop line while minimizing yield loss. As the strip advances, it dynamically tracks the crop position and interfaces with the mill PLC to execute coordinated shear cuts, while also detecting the strip head/tail position and identifying surface cracks that develop during rolling.

APPLICATIONS

The C865C system can be implemented to support shear operations in configurations involving either single end cropping, where only one side of the strip is cut, or double end cropping, where both the head and tail of the strip are removed. The system provides the necessary detection and tracking capabilities to ensure accurate cut positioning under both operational conditions.

 

  • ACOS C865C1 FOR SINGLE END CROP

For single end cropping applications, the C865C system is installed between the roughing mill and the shear. The system configuration typically comprises two ALUMIVIEW sensors C865A and C865S, a laser Doppler velocimeter ACCUSPEED ASDH, power supply units, and a floor mounted control cabinet. The cabinet accommodates the C865C processing units, the ASD electronics unit, maintenance PC, and the associated input/output modules required for system integration and signal exchange.

 

  • ACOS C865C2 FOR DUBLE END CROP

The Aluminum Crop Optimization System for double-end strip cutting is configured to enable defect detection and crop optimization at both the head and tail of the strip. The system comprises two ALUMIVIEW sensors (C865A and C865S) and two laser Doppler velocimeters (ACCUSPEED ASDH), which are installed upstream and downstream of the shear, respectively. In addition, the system includes dedicated power supply units and a floor mounted control cabinet.
The control cabinet houses the C865C processing units, the ASD electronics units, maintenance PC, and the associated input/output modules necessary for system integration, signal acquisition, and communication with the mill automation infrastructure.
