Overview

The LIMAB HotProfiler is a mill gauge for measuring the diameter and shape of hot rolled bars. The HotProfiler measures the profile directly using up to 24 lasers that simultaneously capture the true cross section, outer diameter, shape and ovality. The system not only provides very accurate measurement but is almost free from regular maintenance. Reliable and accurate measurements provide rolling mill operators with instant feedback of the bar shape and dimensions. Reducing mill set-up times and providing better yield from new or existing mills. The HotProfiler is proven and used by many of the best known quality steel producers whether they are conventional or 3 block rolling stand  mills.

Operating Principle

The HotProfiler uses the principle of  rotating optical triangulation; up to 24 laser sensors are mounted on a circular base plate with the lasers directed to the centre of the wheel. The wheel rotates at a constant speed.  Each laser precisely measures the distance to the hot bar. The HotProfiler has a patented algorithm ensuring that the movement of the object in the measuring field does not affect the measuring accuracy.

Applications

• Hot rolled round, square, hex or rectangle sections – full profile measurement
• Cold round tube diameter & ovality inspection – complete cross section profile
• Measurement of cold round or square bars for final inspection
• Measurement of hot blooms and billets
