The HotProfiler is a multi axis non contact mill gauge providing high accuracy cross section profile and shape measurement on hot or cold bars. Suitable for small or large sized steel products, the system will display the true cross section profile and provide min, max diameter, ovality, length waviness, length and other size information.
Suitable for measuring: rounds, squares, rectangles, flats, triangles, hexagons and angles. Also for tubes and pipes.
The Hot Profiler is an oscillating profile measurement system designed for in-line measurement of products in section and bar mills. The system measures on hot or cold rolled material passing through the gauge and present measurement in 2D and 3D graphs as well as numerical values of key figures.
The HotProfiler uses up to 18 synchronized laser
triangulation sensors mounted on a circular base plate
with the lasers directed to the centre of the wheel. The
mounting angle between the lasers is 20 degrees and the
wheel oscillates through an arc of ± 150 degrees. Each
laser precisely measures the distance to the hot or cold bar. The
software incorporates a patented algorithm ensuring that the
movement of the bar in the measuring field does not affect
the measuring accuracy. This method gives a high number
of highly detailed cross sections which provides a much
more detailed analysis of the shape than a typical 4 or 6 axis
shadow based measuring system. Furthermore this principle
detects all concave and convex surface defects. The system
incorporates an automated self centring mechanism to
adjust the height of the measuring wheel to suit the mill pass
line. A pyrometer measures the material temperature for hot
to cold conversion of the measurements. A large remote
display shows key measured values.
Round/hex bars from Ø 5mm to Ø 650mm
Square bars (a x a) in the range a of 5…600mm
Flat bars (t x w) in the range of (t=5…80) x (w=20…600)mm
The software is designed for client/server mode. Several clients can be connected to one server. The server software collects data from the measurement system and handles communication with 2nd level systems. The client software calculates and displays the shape of the measured product graphically with cursors for max/min and two selectable cursors. Trend graphs show key dimensions over the length of the product. Numerical values display key figures of the product and the material temperature as well as the temperature inside the measurement frame. Nominal data from the 2nd level system is also presented. Hot measurement data is converted to cold data.
Complete cross section profile measured with no missed areas
Instant recognition of rolling errors such as underfill, overfill,
roll misalignment, concave and convex surfaces, allowing
operator to take immediate action reducing scrap.
Mill setup time dramatically reduced between product changes, eliminating need for manually measuring of bars.
