Hertwich Receives Orders for Ultrasonic Inspection Stations, Batch Homogenizing Facility
11/16/2010 - Hertwich Engineering has been awarded four orders for ultrasonic billet inspection stations, all of them of helical type for volume inspection. Dubai Aluminium Co. Ltd. also placed an order with Hertwich Engineering for the supply and commissioning of a batch homogenizing facility.
Hertwich Engineering 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 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 Co. Ltd. (DUBAL), United Arab Emirates, and at IMPOL d. d. Aluminium Industry, Slovenia.
All four stations are designed for helical inspection of the entire billet volume to detect faults and inclusions, meeting ASTM B 594 class A or B requirements, with flat bottom hole of 1.2 or 2.0 mm, and surface faults 2 mm deep. Billet diameters range from 125 to 450 mm.
The number of probes per unit is determined to meet specific throughput requirements (100,000 to 150,000 tonnes per year). The volume inspection is mandatory for billet suppliers to the automotive and aircraft industries.
In a separate announcement, DUBAL also placed an order with Hertwich Engineering for the supply and commissioning of a batch homogenizing facility.
The scope comprises two batch homogenizing furnaces as well as one air cooling station. Due to the reversing air concept and regulation by flaps, about 20% faster heating of the logs is achieved in addition to improved temperature uniformity, the company claims. The facility is fully automated and heating is regulated through measurement of the air and metal temperatures. The same concept is employed in the cooling station.
Commissioning is scheduled for the end of 2010.
Hertwich Engineering GmbH, Austria, is a company of the SMS group, which is, under the roof of the holding SMS GmbH, a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. It consists of two business areas: SMS Siemag and SMS Meer. In 2009, about 9000 employees worldwide generated a turnover of EUR 3.9 billion.
