Advanced surface inspection along the entire production chain

With its complete range of powerful inspection systems, ISRA PARSYTEC offers full quality monitoring throughout steel production and processing. Our systems are easy to integrate at every production step, from slab to coated sheet. The collected data not only provides a solid decision-making basis for enhancing quality and processes but also leads to waste reduction.

The combination of sensors and specialized illumination technologies, whose parameters can be adjusted to meet specific application requirements, make it possible. High-quality defect data allows users to subsequently pinpoint the causes of defects.

Our solutions for the steel industry are powered by our brand:

Hot Inspection

Hot Rolling

Detect all relevant defects in the hot rolling mill and pinpoint their causes

Optimized material and production costs are achieved by early detection of all quality relevant defects in the hot rolling mill. Conceived for harshest production environment, automated inspection solutions form ISRA PARSYTEC provide early and precise defect identification throughout the entire production step of red hot strips at high speed processing.

This allows users to pinpoint the defect causes and correct them by replacing rollers.

3D inline inspection makes invisible defects visible

By combining 2D inspection with 3D laser triangulation, ISRA PARSYTEC is able to reliably distinguish between material defects and the surface structure of slabs or heavy plates. Invisible to standalone contrast-based 2D, the 3D inspection reliably detects defects on highly structured, extremely hot material.

The unique combination accurately detects and classifies all quality-related defects and measures their depth - right at the start of the production process. 

The inspection data generated is vital for quality evaluation, preventing unmarketable products from being processed further.

 “The decision to partner with ISRA PARSYTEC was made because of the innovative technology of having 2D and 3D in the same sensor. In addition, the expandability and flexibility of the system allowed us to start with a bottom-only solution and add a top-side later.”

Cold Inpection

Cold Rolling

Ensure the highest quality throughout the production process

Identify defect sources for easy correction: ISRA PARSTYEC delivers leading surface inspection solutions for all standard cold rolling and processing applications for the steel industry, from Pickling, Annealing, Stainless Steel Annealing Pickling and Cold Rolling to Galvanizing, Tinning, Organic Coating, Recoiling & Slitting to Skin Pass processes.

The unique multi-stage classification technology provides excellence in defect exact defect naming. Fast, accurate and flexible, the classifier combined with a learning classifier for line specific defects and a pre-set defect database for standard applications delivers oustanding classification performance.

  • Set-up, commissioning and tuning designed for operators not scientists – easy to understand and to operate
  • Integrated, intelligent and intuitive tools to manage image defect collections and classifiers – simple to utilize, highly reliable
  • Classifier tuning without influence on running production including extensive check of tuning results for risk free switch from test to active classifier

In addition to standard solutions, process-specific software modules intelligently connect and evaluate the inspection and process data collected along the production line. Compiling all available information helps uncover important correlations and untapped potential in quality management and production optimization.

The innovative detection technology detects even extreme low-contrast defects in cold rolling, even at high processing speeds and under difficult ambient conditions. Defect-related information influences classification and enhances its accuracy.

Production analytics - Data-driven production efficiency

The web-based production analytics platform allows you to check the system status of all production lines at a glance or analyze production data in detail. With the quality management system, you analyze historical data, monitor current inspection data in real-time, and identify future trends in your production process.

Optimization of production

Dashboards allow you to compare production line and product data onsite or remotely, providing key insights for optimization. This enables you to make informed professional decisions along your value chain to increase the product quality as well as profitability. You can continuously track the progress of optimization measures and present them with visualized advanced reports.

Early detection of production defects

Detect and quickly identify the cause of threshold value violations at every stage of production with live status information and automatic alerts. As a result you can quickly resolve production defects, shorten downtime, and reduce production costs.

Predictive maintenance

You can prevent potential system failures by analyzing real-time data from the sensors and monitoring systems. This allows proactive planning of maintenance, based on the actual condition of the machines, instead of following a fixed schedule. This data-driven approach saves costs through reduced downtime and increased overall productivity, as well as longer production line life. 

Your benefits

  • Time-saving multi-line overviews, one view for all quality-related information
  • Minimize downtime by monitoring system health data
  • Faster reaction to quality issues with quality data monitoring
  • Fast elimination of production defects, reduction of production costs
  • Improved maintenance for reduced downtime, higher overall productivity and longer production line life
