Btu's per Pound to melt different metals?
I've been casting for a while off a friend's blacksmiths forge using
coke as the fuel. It's a fairly easy process, and we haven't had any trouble so far getting up to melts of about 12lbs. of bronze. Takes 15-20 minutes to do a melt from cold metal. I also got out an old foundry text book, which has some useful tables on the energy per pound from burning coke, air consumption etc. No units given - this is a fairly old book. My question is: does anyone know where I can find a table for the energy required to melt different alloys and metals? Not the temperature required, but the total energy required to get the melt. I'm looking at building a coke furnace, and I'd like to be able to do some ballpark estimates on how much metal could reasonably be poured. regards, Matt Turner Turner Racing Shells Ltd. |
