Large furnaces melt the iron and stay at temperatures ranging 2,600 to 2,800 degrees Fahrenheit. Computerized systems constantly monitor temperature. As the iron travels down the molding line, the temperature gradually decreases from about 2,600 to 1,200 degrees. As the castings cool, they enter a shakeout process in which the molds are shaken off and the sand is recycled for reuse. When castings get below about 140 degrees, they are cleaned and finished.

Compared to iron's melting point -- 2,786 degrees Fahrenheit -- the average melting point of brass at 1,688 makes it a low-melting alloy.oad the crucible with the brass that you would like to melt down. Use a crucible that is made from a clay-graphite mix, as metal crucibles may melt during the process. Lower the crucible into the furnace with a pair of tongs.
