IPC: C21D9/04
Abstract: 106,928. Sandberg, C. P. Oct. 4, 1916. Hardening.-A method of heat-treating rails, switches, points, crossings, and the like in situ or otherwise for the improvement of the wearing surfaces consists in heating them progressively from end to end to a temperature above the critical range, only a small portion of the face being heated at one time, but to a considerable depth, and subsequently cooling the heated portions by quenching or otherwise, such as by the means described in Specifications 18972/14, 1878/15, 8257/15, and 8258/15. The heating-means may be a blowpipe or other flame, and a refractory shield mav be interposed between the flame and the article. The burners and cooling-devices may be moved over the rail or the rail may be moved under a fixed burner and cooling-device. The cooling-medium is directed on to the rail as close behind the flame as possible, and, where water is used, an air jet may be interposed between the flame and the water, and a jet of air or water may also be used in advance of the flame. In treating tramway rails in situ, the adjacent paving blocks may be protected by clay, asbestos, &c.
