Abrégé

An elongated rolled product (2) made of metal is conveyed through a working region (3) of an inductive heating element (1) in a transport direction (x) by means of a transport device (4) such that first a rolled product head (6), then a starting region (7) which adjoins the rolled product head (6), then a central piece (8) which adjoins the starting region (7), then a terminating region (9) which adjoins the central piece (8), and finally a rolled product foot (10) which terminates the terminating region (9) enter the working region (3) and then later exit the working region (3). The working region (3) is the region in which the inductive heating process is carried out. The starting region (7), the central piece (8), and the terminating region (9) are defined in that at a first point in time (t1) at which the rolled product head (6) exits the working region (3), the transition from the starting region (7) to the central piece (8) enters the working region (3) and at a second point in time (t2) at which the rolled product foot (10) enters the working region (3), the transition from the central piece (8) to the terminating region (9) exits the working region (3). Prior to the first point in time (t1) and after the second point in time (t2), the controller (11) operates the inductive heating element (1) according to a voltage control, and between the first and second point in time (t1, t2), the controller operates the inductive heating element according to a power control.

Abrégé

A flat metal rolling stock (2) extends transversely to a longitudinal direction (x), from a left to a right rolling stock edge (3, 4). By means of a first inductive heating device (5), the left rolling stock edge (3) is heated more intensely than the right rolling stock edge (4), and by means of a second inductive heating device (6), the right rolling stock edge (4) is heated more intensely than the left rolling stock edge (3). During the heating of the two rolling stock edges (3, 4), characteristic variables (K1, K2) are recorded which are characteristic of the heating of the respective rolling stock edge (3, 4). The characteristic variables (K1, K2) are fed to a control device (8), which determines a control command (P1, P2) based on the ratio (k) or the difference (δK) between the two characteristic variables (K1, K2). Based on the control command (P1, P2), a lateral position of at least one of the two heating devices (5, 6) relative to the rolling stock edge (3, 4) that is heated more intensely by the particular heating device (5, 6) is adjusted. The control command (P1, P2) is determined by the control device (8) in such a way that the ratio (k) of the two characteristic variables (K1, K2) is brought closer to a setpoint ratio (k*) or the difference (δK) between the two characteristic variables (K1, K2) is brought closer to a setpoint difference (δK*). The setpoint ratio (k*) or the setpoint difference (δK*) can be re-specified to the control device (8) directly or indirectly by an operator (15) at any time.

Abrégé

A planar rolled stock material (2) made of metal is heated in an induction furnace (1). The rolled stock (2) passes through the induction furnace (1) in a longitudinal direction (x). It extends transversely thereto from a first to a second rolled stock edge (3, 4). The induction furnace (1) has a plurality of module pairs (5) which, viewed in the longitudinal direction (x), follow one another sequentially and each have a first and a second induction module (6, 7). The induction modules (6, 7), as viewed in the transverse direction (y), are positioned at a respective initial position (p1*, p2*), so that the first induction modules (6) are arranged offset towards the first rolled stock edge (3) and the second induction modules (7) are arranged offset towards the second rolled stock edge (4). The induction modules (6, 7) are each supplied with electrical power via their own power supply device (8), which is assigned in a proprietary manner to the respective induction module (6, 7). A respective electrical target variable (I1*, I2*) is defined for each induction module (6, 7). It is monitored whether actual variables (I1, I2), with which the induction modules (6, 7) are operated, correspond with their respective target variables (I1*, I2*). In the event that only one actual variable (I11), with which one of the first induction modules (61) is operated, has a reduced value compared with its corresponding target variable (I11*), the target variables (I12* to I15*) for the remaining first induction modules (62 to 65) are increased, while maintaining the operation of all the second induction modules (71 to 75), so that any reduced heating of the rolled stock (2) caused by the reduced actual variable (I11) is compensated as much as possible. This applies to both those first induction modules that are arranged upstream of the first induction module (61) for which the actual variable (I11) has a reduced value compared to its corresponding target variable (I11*), as well as to the first induction modules (62 to 65) which are arranged downstream of that first induction module (61) for which the actual variable (I11) has a reduced value compared to its corresponding target variable (I11*).

A method and an installation for inductively heating flat objects that are transported in a feed direction. The installation has at least one transverse field inductor device which extends transversely to the feed direction over the width of the flat object and has a longitudinal axis running parallel to the transverse axis of the flat object. The transverse field inductor device is positioned such that the longitudinal axis extends in a vertical plane obliquely with respect to the transverse axis of the flat object. With the method it is possible to vary the distance between the flat object and the inductor device and thus the temperature distribution over the transverse profile of the flat object so that the flat object is heated homogeneously.

The functional condition of an induction crucible furnace is checked by first establishing a set-point parameter corresponding to an optimum functional condition of the induction crucible furnace and characterizing the vibratory behavior of same. Then, during normal operation of the furnace, an actual-value parameter of the vibratory behavior is determined. These two parameters are then compared and, if a magnitude of a difference therebetween exceeds a threshold, an alarm is generated.

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.

The invention relates to a method and a device for identifying an earth fault in an induction furnace, as well as an induction furnace. When the presence of an earth fault has been determined with the aid of said earth fault identification device, said earth fault is located, and it is determined whether the fault is caused by a failure of the fire-resistant lining or is the result of other causes. If the earth fault has other causes, it is determined whether it has been caused by a faulty magnetic yoke insulation. It can also be determined which magnetic yoke of the induction furnace is causing an earth fault. This allows the induction furnace to be operated with improved safety and reduced overheads.
