Title: Method for inductively heating valve seats
IPC: C21D1/10
Filed: 1972-02-14
Abstract: 1387125 Induction heating GROWTH INTERNATIONAL Inc 14 Feb 1972 [9 June 1971] 6792/72 Heading H5H [Also in Division C7] The conical valve seat of a ferrous I.C. engine component is hardened by placing a generally circular inductor 20 adjacent the valve seat 10, energizing the inductor 20 from a power source 40 having a frequency greater than 250 kHz, maintaining the inductor 20 energized for a given time to transform the metal forming the valve seat into an austenitic structure to a selected depth, and then allowing the valve seat material to quench out by conduction from said valve seat to the engine component. Because of the non-uniformity of the mass of the engine component adjacent the valve seat 10 the inductor 20 is designed to heat the valve seat non-uniformly, so that a uniform heating pattern is established. Because the mass of material adjacent the valve seat 10 where it is closest to an intake port C is small, supply leads 30, 32 extend radially from this point to coaxial tubes 34, 36 respectively and the inductor 20 is widely spaced by a distance Z from the valve seat at this point. At the point on the line 3-3 in Fig. 1 the inductor is fairly widely spaced from the valve seat to reduce heating whereas at the position on line 2-2 the inductor is closely spaced to increase heating of the valve seat at this point which is adjacent a large mass of material. As shown in Fig. 4, the inductor comprises a generally rectangular conductor 22 which in use is arranged with its surface 26 parallel to the surface of the valve seat 10. Because at the position shown in Fig. 4 there is less mass above the valve seat than below it the surface 26 of the conductor is chamfered at 72 so that the upper part of the valve seat is heated less than the lower part. At the position 2-2 a chamfer is formed at the lower part of the surface 26 of conductor 22 so that the upper part of the valve seat is heated more than the lower part. In operation, when the inductor 20 is positioned a starting device 48 is actuated to energize the radio frequency source 40. After a preselected time a time delay device denergizes the R.F. source 40 and the engine component is removed. Alternatively, when the inductor 20 is positioned the starting device 48 first energizes a high power source 50 having a frequency of 290 kHz. After a short time a time delay device 52 de-energizes high power source 50 and energizes the normal source 40.
