- the device 1 is characterized by a horizontal distance A Ho ris between the side guide member 60 and 61 and an immediately adjacent induction heating 4, 5, 6 and 7, a Indulementscreamimplantation begangsumble BIND and a
- the two side guide elements 60 and 61 each define an effective usable Walkerumblenumble B e ff, which is smaller than the inner dimension BIND of the induction heating 4 to 7, as shown in the illustration of FIG 5.
- the device 1 is still equipped with a conventional leveler 70 comprising five straightening rollers 71 (only exemplified), which is placed in front of the actual heating section 8.
- a conventional leveler 70 comprising five straightening rollers 71 (only exemplified), which is placed in front of the actual heating section 8.
- the leveler 70 By means of the leveler 70, the elongate metallic rolling stock 2 is leveled in a manner known per se before it reaches the front drive unit 21.
- a second embodiment is shown in Figures 3 and 4, wherein in the following essentially only the features will be explained, by which this second embodiment of the first embodiment (see Figures 1 and 2) differs.
- this second embodiment of the first embodiment see Figures 1 and 2 differs.
- each of the induction heaters 104, 105, 106, and 107 has an upper part 32 and a lower part 33 which can be displaced relative to each other so that the induction heater passing height HIND can be variably set.
- the induction heating elements 4 to 7 are mounted in a frame of the device 1, not shown here, so that their upper and lower parts 32 and 33 can independently perform vertical movements according to the vertical arrows 72 (numbered only as an example).
- At least the upper Abweisergleit institute 35, 38, 41 and 73 also independently of each other vertical movements according to the other vertical arrows 74 (only exemplified), so that these compared to the lower Abweisergleit implantn 34, 36, 37, 39 and 40 and with respect to the Rollgangsrolleniden 27th and 28 are height adjustable.
- the induction heating elements 104 to 107 can be moved laterally according to the direction of the arrow 75 and the upper Abweisergleit institute 35, 38, 41 and 73 can be moved laterally according to the direction of the arrow 76 independently.
