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.
Temperature of the welding arc may reach 3316 deg C (6000 F) Temperature of the plasma arc may reach 33 358 deg C ( 55 000F) Melting temperatures of the metals range from 260C (500F) to more than 2760C (5000F) Furnace and refinery stacks can operate at 1093C (2000F) or more. Gases used in the welding process may be stored at temperatures as low as -268C (-452F) Treating burns.
