One of the primary development targets in contemporary automotive technology is the reduction of fuel consumption via the enhancement of the efficiency of turbocharged gasoline engines. The results include an increase in exhaust temperature at the exhaust ports to over 1000° C and greater demands on the mechanical strength, creep behaviour, fatigue resistance, microstrucural stability and resistance to oxidation of the materials used.

The die forging process has high demands on precision to the process accuracy, the reproducibility and the job safety. This counts especially for the first step in process, the heating of the parts to forging temperature. Here the use of induction heating has proven widely. In 2012 a forging company in Hagen replaced a gas fired rotary furnace by an induction heater. This paper shows the practical requirements to the heating process and describes the basic design of the induction furnace for the solutions of the tasks in an automated forging line.

A method and an apparatus for detecting a ground fault in an induction furnace as well as an induction furnace are described. When a ground fault is detected by means of the ground-fault detector the ground fault is localized. By doing this it is determined if the ground fault is caused by a failure of the refractory lining or by other reasons. If the ground fault is caused by other reasons it is ascertained if it is caused by a defective magnetic yoke insulation. Furthermore, it can be ascertained which magnetic yoke of the induction furnace causes a ground fault. In this manner the induction furnace can be operated with improved security and smaller expense.


Patent

An apparatus for detecting ground faults in a multifurnace installation with at least two induction furnaces and a multifurnace installation are described. A ground-fault sensor is associated with each induction furnace and is connected to the electrical supply line to the induction furnace coil. Furthermore, the apparatus has a ground-leak sensor. Moreover, the apparatus includes an additional ground-fault sensor that measures at the same location as the ground-leak sensor. In this manner an improvement of security during the operation of the system is obtained.
