SLAB DIMENSION & ALIGNMENT CHECK

Measure accurately. Align precisely. Eliminate waste before it rolls forward.

Steel-8 copy

PRECISION BEFORE PRESSURE. QUALITY BEFORE CUTTING.

Steel-8 copy 2

Slight misalignments or dimensional inaccuracies in steel slabs during early stages can snowball into major product defects downstream. Manual caliper checks or edge-based sensors are limited in both accuracy and coverage, leading to off-spec output, wastage, and line slowdowns. AI-powered Slab Dimension & Alignment Check uses real-time computer vision to measure slab width, thickness, edge straightness, and alignment during rolling. It continuously validates dimensions against set tolerances and flags deviations, ensuring the process stays precise from the start.

OUR HOLISTIC VIEW TO CHALLENGES & FEATURES

Challenges

Off-Spec Dimensions

Off-Spec Dimensions

Inaccurate width, thickness, or shape leads to product rejection or trimming loss.

Edge Misalignment

Edge Misalignment

Crooked entry into rollers or downstream units causes uneven rolling or jams.

Manual Sampling Delays

Manual Sampling Delays

Spot checks don’t capture continuous variation across slabs, especially under high speed.

Difficulty Maintaining Uniformity

Difficulty Maintaining Uniformity

Thermal expansion, inconsistent feed rate, or load fluctuations distort slab consistency.

Features

Real-Time Dimensional Measurement

Real-Time Dimensional Measurement

Captures continuous width, thickness, and tapering across slab length in millimeters.

Edge Detection & Alignment Analysis

Edge Detection & Alignment Analysis

Tracks deviation from centerline and detects lateral shifts during rolling.

Tolerance Deviation Alerts

Tolerance Deviation Alerts

Operators are notified when slabs fall outside configured dimensional thresholds.

Auto Sync with Roller & Cutter Controls

Auto Sync with Roller & Cutter Controls

Can auto-adjust cutters or side guides based on alignment feedback.

WHO BENEFITS FROM SLAB DIMENSION & ALIGNMENT CHECK?

Artboard 1 copy 6
  • Rolling Mill Engineers – Monitor accuracy live to reduce rework and improve output quality.
  • Quality Assurance Teams – Validate that every slab meets customer specifications in real time.
  • Control Room Operators – Quickly act on deviation alerts without halting the line.
  • Maintenance Heads – Detect mechanical alignment faults from repeated deviation patterns.

BUILDING AND DEPLOYING PROCESS

Surface Defect
Critical Point Placement Strategy

Critical Point Placement Strategy

We work with your production and QA teams to identify the most dimension-sensitive sections, typically between caster exit, descaler zone, and initial roughing stands.

Multi-Angle Camera Configuration

Multi-Angle Camera Configuration

High-speed, high-res cameras are mounted at 3+ angles (top + both edges) to capture slab shape and line position. Each setup is calibrated for steel grades and light conditions.

Dimension Profiling Model

Dimension Profiling Model

We use past QC logs to train models that identify when and how slabs deviate, whether due to uneven cooling, feeder irregularity, or guide misalignment.

Process Correction Integration

Process Correction Integration

Deviation triggers are integrated with hydraulic rollers, guide controllers, or cutters, either for manual override or automatic micro-adjustments. Logs are archived for post-shift quality reviews.

AI Vision in Chemical Mechanical Planarization (CMP) Quality Monitoring

Every chip in your phone, your laptop, or even in a satellite, begins as a plain slice of silicon. But before that slice can become the heart of advanced electronics, it has to go through a series of complex processes. One of the least understood, yet most critical of these, is called Chemical Mechanical Planarization, […]
