Length-based Quality Data in any resolution

Continuous processing lines need length-based quality data for product qualification. The quality data recording system ibaQDR acquires data time-based at different measuring locations and assigns the measurement values precisely to the length position of the product.

ibaQDR at a glance

  • Recording system for quality data, based on ibaPDA architecture
  • Technological process des­cription of strip processing lines
  • Length normalization to the final product (exit coil) and synchronization of all measured data
  • Consideration of strip elongation in the process and all cuts
  • Standard length resolution: 1 m (fully adjustable incl. unit)
  • Scalable number of measuring locations and signals
  • Integration of ibaCapture data
  • Additional time-based recording as an option
  • Data storage in iba *.dat format related to the exit coil and additional to the entry coil

Quality data acquisition of today, is an essential part of the production process for every manufacturer of high-quality products

The quality data recording system ibaQDR is smoothly integrated in ibaPDA as an add-on. The user has the same look-and-feel like in ibaPDA. This offers a transparent quality data acquisition and an efficient data management.

A product (coil)-related analysis of quality data only makes sense, if the relevant measured values can be mapped exactly to the product. In case of long products, a length-based mapping of the data over the product is usually required, e. g. feet-wise or meter-wise.

ibaQDR does this mapping based on the previous time-based recorded data in combination with accurate data of the material tracking. The successively recorded (time-based) data are mapped exactly to the product at the point where they have been measured.

The system has been optimized for rolling mills, processing lines and inspection plants within the metal industry but it can also be used for reversing rolling processes in hot rolling mills or other processes.

Quality relevant data are:

Product dimensions (width, thickness,...)

Cross profiles (strip coating, thickness cross-profile,...)

Production parameters (rolling forces, tensions, ...)

Reference values and consumption figures etc.

Functional Principle

The production line is divided into several sections (measuring locations), where the quality relevant data are acquired. At first, the measuring data are recorded separately based on the measuring locations, together with the material ID and the position (length) of the strip in relation to the measuring location.

This creates as many measurement files as measurement locations. When the product (coil) is finished (e.g. defined by shear cut) the measurement data are extracted from the temporary single files based on the material ID and the length positions and will be written into a new file – the QDR data file. All measurement values belonging to the recently produced strip are stored scaled to the final product length. Production- related material elongations are taken into account.

Product Features

Easy Configuration and wide Range of Interfaces

ibaQDR is based completely on ibaPDA and the iba hardware. Therefore the whole iba connectivity is available. The signals to be measured are configured in the same I/O Manager as in ibaPDA.

Online Status Display

The status of the recording is monitored continuously in a special window showing the current material-ID and length at the measuring location, no matter whether a recording is running or not.

Configuration of the Measuring Location

Besides the name of a measuring location further information is entered in the configuration dialog, such as control signals from material tracking, like material- ID and actual length position.

Scalable System Size

An appropriate number of measuring locations can be defined throughout the line. Another arbitrary number of measuring signals can be assigned to each measuring location.

Analyzing with Standard Tools

The data files which are generated by ibaQDR can be analyzed and displayed with ibaAnalyzer. Demanding reports can be generated with the powerful report generator.

Quality Data Management

Using the software ibaAnalyzer-DB the recorded data can be provided to higher level systems, such as MES (Manufacturing Execution System), DataWarehouse or individual applications in a plain and transparent database structure.

This Software is one of many useful Add-ons of ibaPDA

As the central core of the iba system, ibaPDA has proven itself as one of the most versatile data acquisition systems for maintenance and production for many years. Among the many powerful features of ibaPDA are asset-agnostic acquisition, high-speed synchronous archiving, and real-time streaming analytics.

Please note: As ibaQDR works in close relation to the segment mapping of the automation, a detailed knowledge of the functioning of the automation is required for the configuration.

Therefore we recommend the integration of the system through a qualified supplier or together with support services (consulting, training, support).
