Metal Casting Technologies : March 2006
January 2006 The Editor. METAL Ken Foulke. Marks out of 10 for two questions raised. I am quite surprised that there was only one attempt to answer the questions when I think of all the expertise in casting manufacturing and suppliers who reportedly read this magazine. Hearty congratulations to Bryan Weickhardt of Vesuvius Australia for having a go. Q1. How do you de-gas a furnace full of aluminium, when you have no de-gassing tablets or Nitrogen ? Bryan gets 1 point for having a go and 3 points for skirting around it. That's a score of 4 out of 10. The answer is not in the information given. We want a clear answer to score 10. CLUE. It's not a trick question and the answer is simple. Q2. Can Ductile Iron castings be successfully welded? On the basis of how the question was put, Bryan gets 10 out of 10, and rightfully so. In effect the question inferred ' what method of welding is most successful in joining ductile iron castings? (Fred originally phrased it badly ) Bryan's suggestion to contact DIS was done. The jury is still out on the full answer to the inferred question. Does any body else want to have a go? The answer is not as simple as Q1. From Fred the Foundryman Letters to the editor So again I want to invite you to e-mail us, fax us or just write a letter if you have some comments to make regarding the current issues affecting you in your foundry, the content of the magazine or the state of the foundry industry in general. And I want to stress that this forum is open to all of our readers, no matter what country your foundry is located in, how large or small your scope of operation may be or what position you have in your foundry. I know from my travels that many of you in Asia read each issue of the magazine. Let's hear from you! There is one letter this issue from dependable Fred the Foundryman in which he is continuing the discussion on his first forum submission (made a couple of issues ago). You will find this letter right next to my editorial! Any further submissions, rebuttals, comments? Also of significant import, however, is an article that Fred has done addressing the issue facing us in Australia of what to call ourselves; foundries or casting plants? (This is the controversy I referred to in the second paragraph above.) You will find this article on Page 39. I am very interested to know what you think about this topic. You should certainly have your say and you are welcome to do so through these pages. (Incidentally, I am not trying to go around the AFI National Council in inviting your opinions here, merely adding to your available options for communicating your feelings.) Further to the issue at stake here in Australia, what are the thoughts of our readers elsewhere? Is this an important issue for those of you located in Asia? We'd very much like to hear your thoughts on this or any other topics you feel to be of importance. So, a new year ahead, new issues facing us in our foundries and a new magazine for your perusal. We are anxiously awaiting you e-mails, faxes and letters. See you soon. Ken Foulke METAL Casting Technologies March 2006 5
