Metal Casting Technologies : March 2006
10 BRIEFINGS Data Base for Steels and Alloys The Department of Physical Engineering, National Technical University in the Ukraine has created an Internet Database of Steels and Alloys and contains information on classification, chemical composition, critical points, Brinell hardness, physical, mechanical, and technological properties of more than 1,500 steels and alloys from CIS countries (Russia, Ukraine, Kazakstan etc.). Database. The Web site has both Russian and English versions and is free of charge. It contains broad information on CIS steel standards and grades and could be very useful for businessmen and engineers throughout the world. English version can be found at www.splav.kharkov.com/e_main.php. For further information, email: email@example.com. New Arena-flow1 Software Upgrade Released by Ashland Taking a virtual look into sand core- making and tooling design just got better due to several innovations released in the new Arena-flow version 5.5 computer- aided engineering software from Ashland Casting Solutions. A new proprietary transient curing model has been added to the software. This feature simulates the progression of the catalyst curing front as it passes through a cold-box sand core. Users can specify various process conditions such as amount of catalyst, gassing pressures, gassing times and more to optimise tooling designs. Core-making cycle times can be minimised in a virtual environment prior to the production of expensive cold-box tooling, significantly reducing start-up times and costs. In addition to the new curing model, users will find marked improvements in several core blowing models. First introduced in Arena-Flow version 5.0, additional advanced grid generator options have been added to give users extensive functional control. New logic upgrades have also been added to Arena- flow version 5.5 to check for allowable settings in order to maintain high accuracy and minimal mesh sensitivity. "Each of these enhancements has resulted in reductions in set-up and processing times while improving simulation accuracy," said Nigel Yeomans, Ashland Casting Solutions project engineer. No software upgrade is complete without making the software more user friendly, and Arena-flow version 5.5 meets that challenge by adding a new smart interface. The software will now detect and correct user input errors thanks to an enhanced error-checking algorithm. Extracted from foundry-planet.com Annual Taiwan Foundry Meeting The Taiwan Foundry Society (TFS) recently presented Mike Swartzlander, general manager, Ashland Casting Solutions, and vice president, Ashland Specialty Chemical, a division of Ashland Inc. (NYSE: ASH), with an honorary TFS membership. Swartzlander was the keynote speaker for the annual event. The TFS annual meeting brings foundry professionals together from throughout Taiwan. Dr. Weng-Sing Hwang, TFS president, presented Swartzlander with the honor after he delivered his talk, "The Golden Age of Castings- 2005-2050." "Taiwan is a very important castings market, ranking 12th in world casting production," said Swartzlander. "We recognize the skills and dedication the Taiwanese people bring to the global metal castings market." Taiwan is recognized as having many growth opportunities in the castings market. For example, the national government recently announced a $3 billion wind-turbine electric generation project. "The goal of this project is to install 1000 windmills (2000 MW) in Taiwan by 2010. The project requires multiple, large and sophisticated castings to be made in Taiwan. New NDT Qualifications NDT personnel qualification in two new categories has been developed by the Australian Institute for non-destructive Testing (AINDT). As a result of an Australian industry request, AINDT has developed a qualification program for personnel carrying out testing of above ground storage tanks using magnetic flux leakage (MFL) techniques. This program is based on AS4635 / ISO 20807, Qualification of Personnel for Limited NDT, and guidelines contained within API 653 Appendix G. Examinations for this qualification, titled Tank Bottom Testing (TBT), have been available through the AINDT Certification Board since the July 2005 series of examinations. The TBT Qualification requires the candidate to use their company's MFL equipment and procedure for tank bottom testing. Individuals applying for this qualification currently need to hold certification to ISO 9712/AS3998 Level 2 Ultrasonics (or equivalent). As an alternative, candidates will in the future be able to apply on the basis of certification to another new AINDT qualification titled Ultrasonic Corrosion Testing which is also based on AS 4635 / ISO 20807. The Ultrasonic Corrosion Testing qualification is not product-specific and covers corrosion assessment using ultrasonics -- including the use of angle probes. It is expected that examinations for Ultrasonic Corrosion Testing will be available later in 2006. The Ultrasonic Corrosion Testing qualification has a pre- requisite requirement for candidates to hold AS 3998 Level 1 Ultrasonic Thickest Testing (or equivalent). The AS4635 / ISO20807 standard, on which both new qualifications are based, requires two examinations in order to achieve qualification -- one theory and one practical. The qualification process requires a review of each candidate's experience and a pass mark in both the theory and practical examinations.
