I have been playing with my scrapping furnace again and gave it a run with a practical application, Melting a cylinder head.
Here is Oz steel is worth nothing although non ferrous is still holding well. For an engine that has aluminum manifolds, casing and heads, they still only pay steel prices which to me is a crock. The idea with the scrapping furnace is to have a fast and low cost way of separating the ally from the steel so the max profits can be gained from each.
As there were no complete engines at the yard when I was there, I bought back the biggest bits I could find being a couple of quad cam Heads. They weighed 11KG each and only took 5.5 min to melt all the ally off. I could have done it much faster had the oil been flowing better ( I intend to do a twin feed on my tank) and I positioned the head more upright to catch more of the burner output.
I have a bunch of smaller stuff saved up so when I get a chance to bring it down and hopefully a whole engine, I'll do those as a big melt and make another vid.
A side benefit of melting these bits down is that it also gets rid of all the waste oils from the wrecking yard that the collectors charge plenty to come and take away.
