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.
At room temperature, iron is in the form of ferrite, or Î±-iron, a body-centered cubic structure. The density of Î±-iron is 7.86 g/cc. At 910Â°C it changes to Î³-iron, which is face-centered cubic and somewhat softer. At 1535Â°C iron melts, and boils at 3000Â°C.he magnetism of the iron group of metals is a rare and remarkable property. It is not due to any inherent magnetic propensities of the atoms, but to the structure of the metal. Other substances with similar structures also have similar magnetic properties.
