LaseSDM - Slab Dimension Measurement

Length, width, thickness and shape - slabs can be measured in all of their dimensions: The solutions by LASE are configured modularly in order that measurements are according to customers' requests.

System features for LaseSDM - Slab Dimension Measurement:

  • Lenght
  • Width
  • Thickness
  • Shape (wedge and saber in horizontal orientation)
  • Shape (saber in vertical orientation)

The measuring frame (see picture above) consists of systems for width-, thickness- (two-lane) and length metering. The lasers for the width measurement are adjustable in their height and the lasers for thickness measurements are adjusatble in their width.

Short description:
The laser triangulation meters are built into a measuring frame which accommodates adjustments of the measuring devices for different slab widths and thicknesses. By means of the triangulation sensors the slab width and thickness is determined very exactly.
On two rollers in front of the measuring frame two incremental rotary encoders are mounted. The turns of the rolls are registered and with additional input of the laser meters, the length of the blocks is determined by both encoders.

For cooling purposes, the laser distance meters are implemented in air scavenged and water cooled housings. Fresh air is sucked in by a ventilator with an upstream filter (situated in the basement), transported and also divided over an air pipe to the measuring frame. The air is also conducted by separate lines to the laser housings. The scavenging air system serves to avoid dust deposits and the cooling plates are integrated in the housing for water cooling.

For these tasks the following types of triangulation meters are built into the measuring frame as follows:

  • Above the roller table: 2 sensors with a distance of 1150 mm
  • Underneath the roller table: 2 sensors with a distance of 700 mm
  • Sideways of the roller table: 1 sensor at each side (right and left) at a distance of 700 mm
  • Two incremental rotary encoders are adapted mechanically and mounted on two rolls
