Ingot measurements on aluminium or steel before scalping

Initial Situation:

Our Client manufactures ingots made of aluminum or steel, which have to be scalped for an even surface. The method currently in use is ingot measurements of the deepest point on the raw surface manually, and adjusting the scalping height of the machine accordingly.

Particular Challenges:

Manual ingot measurements of the deepest point on the raw surface is not accurate enough. This attempt results either in cutting away too much material or in a surface with holes still present. These holes can only be eliminated by a repetition of the scalping procedure.

QuellTech Solution:

The performance of a manual inspection cannot be compared with the speed and the repeatability of a contactless QuellTech Q4-1000 laser scanner. It is even possible to install several instruments in parallel to cover the whole width of the ingot with one single scan. These instruments are mounted on an existing portal and correctly synchronized, so that interaction of the laser light originating from the other scanners is excluded.  The QuellTech laser line scanners produce 3D point cloud of the raw ingot surface, and the software calculates the coordinates of the highest and deepest levels of this surface. After scalping the flat surface can be scanned again for any defects.

Benefits for the Client:

Thanks to QuellTech’s wide area laser line scanners, the cycle times for ingot scalping could considerably be reduced, and excessive material scrap due to a too low scalping level is prevented.
