Confidence votes 25. Steel often melts at around 1370 degrees C (2500 Â°F). This varies depending on the specific steel alloy. The specific heat of steel varied from 420J/KG/Deg C at room temperature to 720J/KG/Deg C at 1535 deg C. This equates to a theoretical heat requirement of approximately 375KWh/mt to melt steel from room temperature. In practice, foundries use between 500 and 800 KWh /mt to raise steel to a little above its melting point of 1535deg C.
The silicon melt temperature was measured for 30 min. The temperature variations at the melt surfaces and bottom with the temperature of crucible top and bottom being 1450Â°C and 1430Â°C are shown in Fig. 4. The concentrations of boron added are non-doping, 1Ã10 18 and 1Ã10 20 atoms/cm 3, respectively.
