Slab Length Measurement

Problem area:

Measurement of Length in Hot Billets/Blooms and Slabs of varying sizes

Issues with current method of measurement:

Earlier, Slab/Billet lengths have been measured using HMD’s or photocells together with a tachometer driven by an encoder. Sometimes, the length is calculated by visual inspection of the bloom. This gives faulty information during the cutting of the bloom

Solution:

To eliminate faulty recordings and to provide high accurate readings, a laser Doppler gauge is the ideal solution. The Laser Doppler system gauge is mounted on a an actuator and is operated using a positioning mechanism which automatically tracks the bar position using a laser displacement sensor. This helps the Doppler gauge to set itself at the ideal position for obtaining high accurate values of both the speed and the length.

The laser displacement sensor helps the system give highly accurate reading despite varying sizes and irregular movement of the product

Benefits:

Provide high-speed, non-contact, solid-state laser speed and length measurement with no slippage, drift or mechanical wear and greatly reduced maintenance compared with contact wheel / roller systems.

Are accurate to better than 0.05% and repeatable to better than 0.02% with UKAS-traceable calibration.

Very less give away there by faster ROI

Can be integrated with cutters for highly accurate cutting

A laser doppler gauge is used for the speed and length of varying bar sizes

Measurement of length in hot billets/blooms and slabs of varying sizes id difficult since sudden variations and improper movement of product causes faulty reading

The laser doppler system gauge is mounted on an actuator and is operated using a positioning mechanism which automatically tracks the bar position using a laser displacement sensor.
