As-cast steel surfaces

• System can acquire data of an entire cast
• 3D profiling, automatically detects and provides topological mapping of the steel surface
• Detects and identifies defects as small as 0.1mm
• Resistant to the harsh hot environment (>1000°C)
• Non-destructive laser imaging technology
• Reduces the reliance on as-cast rectification
• Uses laser-based triangulation and state-of-the-art cameras

3D Stereo Measurement in hot, harsh environments

• Stereo matching algorithms produce 3D representation
• Inspection and monitoring for quality assessment purposes
• Quick detection of defects and faults
• Tailored solutions to give unprecedented levels of resolution and accuracy
• Operates in the most challenging of environments.
• Stereo cameras are housed in water and air-cooled protective housing capable of withstanding temperatures of up to 2000⁰C

Steel Hot Plate Monitoring

• Enhance the efficiency in steel plate mills
• 3D surface reconstruction to detect and identify defects
• Provides dimensional analysis
• Identifies defects on steel plates at an early stage of the manufacturing process
• Operates on steel at 500 – 800°C
• Stereo camera arrangement combined with a laser-triangulation system
• Mounted in a water-cooled housing with integrated air purge
• Detect defects as small as 0.125 mm
• Modular to enable measurement of varying plate widths
