Thanks for the info update.
Now I know what you want to do I can give it some thought.
Here, I can power roll up to 6in wide from 3/8th ins thick.
so thats far too small for your needs.
The cunifer 10 I have here was hot rolled! at a Co called Birmingham
They made, also hot rolled large, as in 10 ft dia copper plate 1/4in
thick for the brewery and distillery business.
Regret there gone now. I sawtheir mill and furnaces. in use!! A
fellow silver smith has made a full size replica of the Battersea
shield, he alloyed his bronze and wrought it out by hand.
There was a long discussion as to wether one made up the melt on
weight, or on parts.
do you alloy on weight? ie say 9 lbs ofcopper to 1lb of tin? Or
calculate the amount allowing for the different specific gravity? In
order to get a final analysis of 90 % copper and 10% tin you have to
allow for the different specific gravity in the metals.
The last time i saw bronze being made was some yrs ago where they
used a continious casting mold of water cooled copper which allowed
the metal to be drawn out of the mold bottom at a steady rate.
It was then fed into a milling machine that took of a 1/16th in off
both sides before it went into the rolling mills.
The large brass strip mills at IMI Witton B’ham work in the same
However the sheet is annealed as a strip some 3 ft wide in a cracked
ammonia reducing tunnel kiln before it continues on to thinner
Id suggest if you havnt already done so, you need to get consistent
results with a small batch of melts before you scale up to the
Here in Europe there are a no of Co’s that would make it for you but
would want a minimum of several tons to warrant the exercise.
Casting between cold stone molds is doubtful, I cast sterling into
cast iron molds heated till alive oil smokes when poured over the
The molten metal burns the oil and prevents oxygen getting to it.
Also i pour through a reducing flame for the same reason.
If you want to correspond further lets do it off list.
