MACPROTEC ENGINEERING / MACREF
Refractory Thickness Inspection & Analysis Software
Measure the Lining. Don't Guess It.
Know what's left in every cyclone.
MACREF is a specialized refractory inspection and thickness analysis software developed by MACPROTEC Engineering for cement plant preheater cyclones.
Using 3D laser scan data and refractory lining drawings, MACREF measures remaining lining thickness, generates detailed thickness maps, identifies critical wear zones, and produces prioritized repair recommendations.
By transforming inspection data into actionable maintenance information, MACREF helps cement plants plan refractory repairs and make informed decisions during critical shutdown periods.
01 / CAPABILITIES
Why MACREF?
From Visual Inspection to Measured Refractory Thickness.
Traditional refractory inspections often rely on visual assessments and manual checks, leaving uncertainty about the remaining lining thickness, particularly in areas affected by coating or difficult-to-access cyclone sections.
This uncertainty can lead to unexpected repair requirements, inefficient maintenance planning, and unplanned equipment downtime.
MACREF replaces guesswork with measurement-based inspection, helping plant teams identify critical areas, quantify repair requirements, and prioritize maintenance activities using actual scan data.
02 / CAPABILITIES
What Makes MACREF Different?
Precision Inspection. Actionable Engineering Data.
3D Laser Scan Integration
Processes interior cyclone scans captured using standard 3D laser scanners with E57 file support.
Remaining Refractory Thickness Mapping
Compares scanned hot-face geometry against refractory lining drawings to calculate remaining lining thickness across the cyclone.
Color-Coded Thickness Visualization
Generates detailed thickness maps highlighting areas approaching or falling below defined critical thickness limits.
Critical Zone Identification
Identifies potential refractory wear zones and prioritizes areas requiring repair, verification, or continued monitoring.
Repair Scope & Quantity Estimation
Produces repair recommendations with estimated areas, refractory volumes, material quantities, and anchor requirements.
Drawing-to-Scan Verification
Checks actual cyclone geometry against design drawings and flags differences requiring further investigation.
03 / CAPABILITIES
Refractory Inspection Applications
Built Specifically for Cement Preheater Cyclones.
MACREF is developed to analyze refractory lining conditions within cement plant preheater cyclones, including:
Cyclone Cylindrical Sections
Remaining lining thickness, localized wear patterns, and critical wall regions.
Cyclone Cone Sections
Thickness distribution, cone geometry, and areas requiring verification or repair.
Cyclone Roof & Inlet Regions
Refractory thickness evaluation around roof transitions, inlet openings, and geometrically complex sections.
Shutdown Refractory Assessment
Rapid assessment of scanned cyclone lining conditions to support repair planning before plant restart.
04 / CAPABILITIES
From Laser Scan to Repair Scope
A Structured, Measurement-Based Inspection Process.
Refractory Drawing
Configure the cyclone geometry using actual refractory lining drawings and design information.
3D Laser Scanning
Capture the interior cyclone geometry during a shutdown using a compatible laser scanner.
Thickness Analysis
Align the scan with the vessel model, verify geometry, and calculate remaining refractory thickness.
Inspection Report
Generate color-coded thickness maps, prioritized findings, repair quantities, and recommendations for maintenance teams.
MACREF converts complex scan data into clear engineering information that supports practical shutdown decisions.
