  Dear Sir, Im trying to cast billets for extrusion 4" x 400 mm and 5 " x 450 mm. U have some tips or advice to have success with this task?

• 
  @swdweeb6 күн бұрын

  I love it when you mix measurement systems 😂 (inches and mm) I assume that 100mm x 400mm and 125mm x 450mm is what you're trying to pour. You're correct in being concerned with shrinkage. Something that big will want to shrink, a lot. If it were me, I'd try to do a bottom-fed, vertical pour with plenty of extra height to allow for the shrinkage. Feeding from the bottom will reduce porosity (assuming you keep your sprue full). I'd also leave the top of the mold open so you can see the metal in the mold as it rises and cools. When you're done, you can cut the billet to length removing the section with the big shrinkage hole in it. Good luck

  I find it's too much of a pain to try to get/keep my greensand the right level of moistness. Petrobond is always ready, 365 days a year. You know you can make your own petrobond, right? Same sand and some chap oil. The only unusual thing you have to source is Bentone (NOT Bentonite!!!) but it's available out there. Costs way less to make than to buy, and just a bit more than greensand in the end. Look up K-Bond sand recipe.

  re table salt; I've read that NaCl or KCl will just lie there unless it actually melts and becomes free ions; but both have a melting point above that of aluminum. If you mix and pre-melt the two chemicals prior to casting at a 1:1 molar ratio, you get a flux that melts before the aluminum; that's the key. So table salt alone probably does nothing unless your melt is way too hot. Most hydrocarbon compounds make a poor flux by themselves, and soap probably decomposes in heat to become a tarry mass of sodium-bearing goo that has *some* noticeable effect on the pour but who knows, even sawdust works for some metals.

  Your sprue is too small and should be full shaped so when it cools and shrinks it’s sucks extra material from the sprue!

• 
  @swdweeb2 ай бұрын

  Absolutely wrong. The sprue is designed to conform to the shape of the metal as it falls thus preventing air from being entrained in the metal as it is moving. Sprues should freeze off before the part freezes. If you want to feed a part then use a feeder that is sufficient to feed a part in the location it requires it. This hammer was a long time ago and I learned the lesson of feeding it properly after making this mistake,

  That is a matter of opinion. Russian bells are not tuned as as a result each has a unique voice. For many this is an important characteristic. "Western" bells are typically tuned or cast in such a way that they produce a collection of frequencies, or partials, around a main note that many find pleasing. I can see the beauty in each

  We machine a lot of bronze at work. We must have 10- 55 gal drums full of bronze scrap. I have cast aluminum before. How much hotter does bronze have to get and also do you have to use any special flux or anything?

• 
  @swdweeb2 ай бұрын

  I pour aluminum at 1325f (718c) and bronze around 2150f (1176c). Bronze has a much higher melting temp between 1570-1830f than aluminum. I don't use any fluxes simply because I don't have any. What I do use with bronze and (shudder) brass is a mixture of broken glass and borax. just a small piece of glass, 3/4" square?? and about a tablespoon of borax poured on the metal with melt and form a glassy lake on the top of the metal greatly minimizing the amount of oxidation created. I also pre-heat my furnace and crucible for 10-15 minutes before putting the metal in. It reduces the time the metal sits there exposed to an oxidizing flame.

  I once made a part that lloked like a dog dish. I foundry guy told me to just ram up a thin drag like you did but then fill the bell with sand and ram it and strike it off then just set it on the drag and rap it until it will come off the sand cone and then put more parting dust on the sand cone and then put the bell back on and then ram the cope. Then hopefully the bell will come with the cope and you can then remove it.

  Great videos. Very informative.. However I've noticed that up to now you haven't mentioned 'feeders' ( the additional void that fills with metal to keep the casting supplied with molten metal as it cools preventing shrinkage) I can see that there is in effect a bit of a one on top of the spin trap, but I'd have thought much too small to feed that large block of casting. The spin trap/feeder ( ? ) would have solidified well before the centre of the large casting. I'm really surprised that it appeared so good and no shrinkage or signs of deforming.
