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.
Magma is the molten form of rock, stored deep beneath the Earth's surface. The temperature of this hot fluid ranges from 1292 - 2372 Â°F. At this temperature, it has the ability to melt the surrounding rock structures to produce more magma. Intermediate magma contains 60 percent silica, but the magnesium and iron content in it is very low. Very explosive in nature, its temperature can be as high as 1832 Â°F. â Felsic magma contains more than 70 percent silica content, but its iron and magnesium content is negligible.
