Helical ultrasonic inspection stations made by Hertwich Engineering guarantee and document that aluminum billets are free from defects
Hertwich Engineering, Austria, has been awarded four orders for ultrasonic billet inspection stations, all of them of helical type for volume inspection.
Two stations have already been successfully commissioned for Hammerer Aluminium Industries GmbH (HAI) at its Ranshofen, Austria, and Arad, Romania, works. The remaining two UT stations are scheduled to be commissioned around the end of 2010 at Dubai Aluminium Company Ltd. (DUBAL), United Arab Emirates, and at IMPOL d. d. Aluminium Industry, Slovenia, respectively.
All four UT stations are designed for helical inspection of the entire billet volume to detect faults and inclusions, meeting the requirements of ASTM B 594 class A or B, with flat bottom hole of 1.2 or 2.0 mm, and surface faults 2mm deep. Billet diameters range from 125 to 450mm.
The number of probes per unit is determined to meet specific throughput requirements (100,000 to 150,000 tpy).
Fully automated ultrasonic inspection equipment is an indispensable instrument to certify and document that billets are free from defects and to achieve best economy of operation. The volume inspection is mandatory for billet suppliers to the automotive and aircraft industries.
