They are correct in saying it sounds like you need to anneal more
often or keep the metal hot before quenching. Another problem can be
contamination in the metal from the crucible. Every once in awhile
the crucible should be cleaned (heated until the slag can be poured
out) or just replaced. Be careful of fumes when melting scrap. Some
may contain older solder which can contain toxic metals. It would be
nice to know how you are going through the process.
You asked the steps of my wire drawing procedure. I had explains it
step by step. Please correct me.
Fist I collect silver and then put into a crucible.
Then the crucible is covered by charcoal and heat silver(I do not
use any special cleaning methods only clean the crucible with a peace
After it is melted pour it in to ingot and try to keep it as a
If It is not shape enough I hammer it to get the shape.
After hammering and get reduce to some extend (hammered three or
four times) and I heated it till it gets red and dip in to water and
hammer it to reduce the size.
When it reduces to a size where it can pass through the rolling mill
I stop hammering.
Then I pass through the rolling mill till it’s come to the size
where it can pass through the draw plate.
Then I draw a wire through the draw plate to get the exat size.
Thanks & Regards,
