Abstract: A device and method for induction hardening rolling tracks of thrust blocks of bearings, according to a required hardening profile. At least two inductors arranged in tandem are used within a track to be hardened, at a predetermined distance from a surface of the track and the thrust block is rotated with respect to the inductors, so as to make them cover the entire track, with a complete 360° turn; the inductors, at least one first pre-heating inductor and one at least heating inductor, are shaped so as to generate a first and a second magnetic fields, respectively, both having flux lines which are perpendicular to each other, and one of the two inductors is mounted on an orientable head so as to be able to arrange the two inductors oriented according to the curvature of the track. The mentioned predetermined distance of the inductors from the track is obtained by using a feeler to accurately detect the geometry of the track and which is introduced between the two inductors and then moved away during the heating steps which are performed sequentially in synchronism with the rotation of the thrust block, and by varying, in a final step, the electric power fed to at least one inductor.

Abstract: The induction coil of a device that heats a toolholder (1) inductively for the tool change comprises a shielding collar (27) of magnetizable material which, firstly, concentrates the magnetic flux of the induction coil (13) in a sleeve section (5) of the toolholder (1) which holds the shaft (11) of a rotary tool with a press fit and, secondly, shields the part of the tool shaft (11) that projects out of the sleeve extension (5), in order to facilitate unclamping the tool from the toolholder (1). On its side facing the winding (19) of the induction coil (13) axially, the shielding collar (27) has an outer circumferential surface (31) which widens conically away from the sleeve extension (5) and an axial height (h) which is at least 1.5 times the diameter (d) of the tool shaft (11). The shielding collar (27) runs on all sides at a distance from a yoke shell (23) of magnetizable material which encases the winding (19) of the induction coil (13).

Abstract: A method and apparatus for carrying out scaleless inductive heating of ferrous parts comprising (i) using an integrated manifold-inductor quenchant device, and while gradually flowing a diluted combustible gas into the spacing between the inductor and part surface to be heated, inductively heating such surface as part of a heat treating cycle; and (ii) concurrently stopping such flow and injecting a fluid quenchant through the spacing to rapidly lower the temperature of the part surface to complete the heat treating cycle. Advantageously such method may further comprise flushing the spacing between the inductor and heated part surface, and then repeating the steps of the prior method to treat more parts with the same inductor.

Abstract: A device for induction heating of the inside of cylinder liners of reciprocating-piston engines to a transformation temperature, for the purpose of hardening. An inductor head is equipper with an aligning device designed as a spreadable cage which is equipped on the outside with clamping bars, clamping bosses a clamping shells which can be applied free from play and under the effect of force against the inner surface of the cylinder liner. The inductor loop is also displaced radially and brought into the working position by means of these clamping shells. Heating and hardening is carried out only with the inductor head in the clamped and exactly aligned state, whereas, after the clamping shells and the inductor loops have been released, a further indexed movement of the inductor head is possible. The work is carried out at relatively high alternating-current frequencies in the range between 400 and 500 kHz and at relatively high energy densities in the range above 5 kw/cm.sup.2 .

Abstract: A brazing apparatus and process which utilizes a dual function heating and eddy current probe coil is disclosed herein. The apparatus generally includes a radiant heater assembly having a coil which is capable of both generating radiant heat to effect a braze joint between a reinforcing sleeve and a surrounding tube, as well as serving as an eddy current probe which locates the sections of this sleeve to which the brazing heat should be applied to effect the desired joint. A switching means selectively connects the coil to either a relatively high, heat-generating current, or to the aforementioned alternating current which induces eddy currents within the metal forming the reinforcing sleeve. The apparatus further includes eddy current detection circuitry for monitoring changes in the coil impedance which result from these eddy currents while the coil is slid along the longitudinal axis X of the reinforcing sleeve. In the process of the invention, the edges of the sleeve are accurately located by noting the position of the coil when the coil impedance attains its first and last local maximum values. Both the apparatus and process of the invention are particularly useful in effecting high-quality braze joints in reinforcing sleeves which are brazed within damaged or corroded heat exchange tubes in nuclear steam generators.
