Mobile Profile Gauge with 300 mm measurement range

Eastloong supply professional and honest service.

CALIPRI RC350 is a contactless portable profile measurement device that both considerably speeds up and simplifies work processes in the steel mill. 
It provides reliable measurement data between passes on hot profiles – efficiently and accurately. Since the RC350 is a portable measuring system, you can place the device at any point in the rolling mill. The C-frame of the housing allows CALIPRI to be used during rolling operation.

The measurement device is powered by a rechargeable battery and uses WiFi to communicate with the tablet PC, meaning that no cabled connections are required. This is a key advantage as it ensures working conditions on the hot rolled material are safe: You can leave the hot area while the measurements are being taken. The CALIPRI RC350 is protected against the high temperatures and water in the rolling. If the conditions for the device become too harsh, an alarm is triggered automatically.

When taking measurements with the CALIPRI RC350, the measurement object is scanned from all sides and angles. This enables even the most complex profile shapes and indentations to be captured.

The measurement result is shown immediately on the tablet PC for instant analysis. Furthermore, the profile data can be exported as point cloud for comparisons and analysis in a CAD program.

CALIPRI RC220 is a contactless portable profile measurement device that both considerably speeds up and simplifies work processes in the steel mill. It provides reliable measurement data between passes on hot profiles – efficiently and accurately. Since it is a portable measuring system, you can place the device at any point in the rolling mill. The C-frame of the housing allows CALIPRI RC220 to be used during rolling operation.

The measurement device is powered by a rechargeable battery and uses WLAN to communicate with the supplied tablet PC, meaning that no cabled connections are required. This is a key advantage as it ensures working conditions on the hot rolled material are safe: You can leave the hot area while the measurements are being taken. CALIPRI RC220 resists the high temperatures for the time of your spot measurement and is water protected. If the conditions for the device become too harsh, an acoustic and visual alarm is triggered.
When taking measurements with CALIPRI RC220, the measurement object is scanned from all sides and angles. This enables even the most complex sections to be analysed. The profile is shown immediately on the tablet PC and deviations can be analysed.

The CALIPRI C42 RollShop Bundle is designed for the fast and highly accurate measurement of roll dimensional properties in the steel mill. The bundle features two measurement methods: 

• The method Roll Caliber enables the measurement of depth and width of multiple grooves in a roll caliber. Up to ten grooves can be measured with one single hand-guided measurement scan.
  Additionally, the feature ProfileCompare can be used to examine the wear of the grooves using a graphical overlay of the groove curve before and after extensive usage. Regular measurement of the roll calibers is crucial in order to assure a constant long product quality and optimize the roll lifetime.
• The method Roll Gap is used for the measurement of the minimum gap between two flat roll sections. This parameter is important in order to produce long rolled products or metal sheets with specified thickness.

The measurement with the CALIPRI C42 handheld sensor is carried out easy and fast. Due to the patented CALIPRI principle the results are extremely reliable: roll and tilt corrections are done by the device automatically in order to generate highly precise, reproduceable and user-independent results.

Measurement plans can be created by drag & drop in the software CALIPRI Manager. The user defines the position of the measurement points, the measurement method and the tolerance ranges of the results. Afterwards, the profile is recorded by a swiveling movement of the CALIPRI sensor. The measurement software CALIPRI Portable Operator then automatically calculates the dimensional results which are displayed both on the tablet PC and on the sensor itself with color coded tolerance classes. Additionally, the captured profile can be compared with reference data by using the featureProfileCompare. The measurement results can be transferred easily via Ethernet, Bluetooth, USB or wireless – allowing print as well as export of the results and profile curves in a variety of common file formats.

With HORUS, MetGauge provides a cost-efficient stationary optical measuring system for continuously testing the dimensional accuracy of coldly formed, thermally treated or hot rolled products of a cross-sectional size up to 300 mm (12 inch). The measurement range is up to 330 mm (13 inch). However, pass-line variations have to be considered. Diameter and roundness, width, height and other measurements on convex shapes (rounds, flats, squares, hexagonal) including reinforced bars with rib structures and L-shaped angles are performed online, results displayed and alarms set, in case the product exceeds its pre-defined tolerances. Product measurements from earlier productions can be accessed through an integrated database for a seamless documentation of product quality.

HORUS Wire can be applied to material temperatures of up to °C (or °F) and ambient temperatures between -10 – 50°C (14 – 122 °F). The integrated cooling/heating system keeps the sensor temperature constant, while very hot material runs through the gauge close to the sensors. Thanks to this early quality control, steel mills can find root causes for defects and implement suitable corrective measures much earlier, reducing their reject rate and associated cost.

HORUS Wire is ready for the use in hot rolling mills, wire or bar mills. The measurement area is a closed ring, allowing to move the gauge out of the line between 2 billets. One data set is collected over one billet and stored in the data base for later retrieval.

Measurements are carried out on a variety of features depending on the cross-section shape or contour of the product. The values are taken  times per second and are compared against the allowed tolerances. The amount of raw data acquired by the sensors is quite big and would fill any reasonable size of mass storage within a short time. Therefore, an advanced filtering of these data is executed.

If the tolerance limit is exceeded, an alarm is generated and the complete contour is stored for further retrieval and analysis, otherwise a regular contour sample is taken, adjustable e.g., every 0.1 s, and stored. For special evaluations selected values, e.g., diameter or height and width, can be stored more often, adjustable up to for every scan, that means  times per second.

For round material, the diameter measurement is essential. HORUS Wire calculates the smallest and the biggest diameter, average and standard deviation as well as the roundness. Also, the angle, under which the smallest and the biggest diameter has been measured, can be calculated. Additionally, the cross-section area is evaluated for every scan, while the meter weight is calculated from the average cross-section area over a reference length (adjustable, usually 1 m).

HORUS Wire measures the following features for rectangular shapes like squares and flats:

Examples of typical and recognizable rolling defects are:

2-6-axes diameter gauge with measurement range 120/150 mm

The standard model ATON Bar is a bar and tube gauge for round profiles. It measures diameter and ovality with 2,3,4 or 6 axes shadow sensors, has a measurement range 120 mm and an accuracy of 15 µm. The 4 and 6 axes version can also visualize rolling defects such as roll shift, over and under fill. With the 3 and the 6 axes version the gauge can measure trilobed rounds, coming from 3-roll mills. The 6-axes version is also able to measure rebar structures with core diameter, rib height and meter weight.

The ATON Bar software shows beside the current measured diameter values from the different axes a polar diagram of the interpolated cross section during the measurement. In a linear diagram, diameters from the different axes, minimum/maximum diameter and ovality are displayed over the length of the billet. The material temperature is also measured by a built-in pyrometer, in order to calculate the cold dimensions using the material’s shrinking coefficient. Rolling speed can be measured from a suitable analogue or digital speed signal.

Retrieval of historic data is possible by a finger click. A diagnosis screen informs about the health of the system. Remote access for maintenance or trouble shooting is possible through the network connection.

Benefit from higher yield and higher utilization by choosing an ATON Bar system. Choosing a sophisticated dimensional measurement system allows for maintaining dimensional accuracy over the entire coil length and enables you to take immediate corrective actions after the detection of deviations.

All housings of ATON Bar have active cooling and purge air. ATON Bar 120 is specified for material up to 100 mm (maximum pass line variation ±10 mm), ATON Bar 150 for material up to 130 mm (maximum pass line variation ±10 mm), both at up to  °C. All versions of ATON Bar gauge can compensate the expansion of high temperature material using temperature data from an external pyrometer and calculation of the shrinking based on temperature coefficients provided by the customer.
