1、电 熔 炉 设 计 基 础 数 据Base data for the design of the electric melting furnace Heat generated per second: 4.5 kJHighest electrical current: 200 A TIG welding machine 10 s: The TIG welding machine can generate about 45 kJ quantity of electric arc heat in the period of 10 second and meantime the heat gener
2、ated can theoretically melt 100 g Fe at least when the melting heat of Fe is 15.508 kJ/mol. So the TIG welding machine is perfect for melting Fe metal at the help of electric arc, but can the TIG welding machine be used as the electrical source for the electric melting furnace ?Suppose: The laden vo
3、lume of the furnace we would design is 0.01m2 0.2 m. The resistivity of Fe obtained from paper is 0.97 10 -7 .m and the resistance of Fe setted in the furnace at the laden volume is calculated as 19.4 10 -7 . As the resistance of Fe is very small, the heat generated by itself is calculated as 0.0776
4、 J per sec at the highest current by the TIG welding machine as the electrical source. Conclusion: The TIG welding machine can not be used as the electrical source for the electric melting furnace because the small electrical current. Analysis procedure Salting transformer The salting transformer can generate high current value, as a result it can be as the electrical source for the electric melting furnace. Thank You
