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.
Melting Your Silver. 1  1. Put on your safety gear and secure the area. 2  2. Place the crucible with the silver object on or in your furnace. 3  3. Heat the furnace to a temperature which exceeds the melting point of silver.  4. Apply your blow torch to the silver, if youâve chosen to use a blow torch. If youâre using a smaller crucible and are melting on a smaller scale, you might have chosen to use a blow torch to melt your silver. If this is the case, take your blow torch and apply it to the silver.
