Firma DT –Vyhybkarna a strojirna a.s. z Prostejova jest producentem szyn i rozjazdów kolejowych. <\/div>\n
Jednym z procesów technologicznych realizowanych w zak\u0142adzie jest obróbka cieplna g\u0142ówki szyny. G\u0142ówka jest ogrzewana indukcyjnie do temperatury przemiany austenitycznej, po czym przetrzymuje si\u0119 j\u0105 w tej temperaturze, a na koniec przeprowadza kontrolowane ch\u0142odzenie celem zmiany struktury stali w drobnoziarnist\u0105, perlityczn\u0105. G\u0142ówka jest obrobiona na g\u0142\u0119boko\u015bci 15 mm, a uzyskana twardo\u015b\u0107 powierzchni wynosi 350 –390 HBW, a na g\u0142\u0119boko\u015bci 15 mm –minimum 300 HV 30. Wytrzyma\u0142o\u015b\u0107 szyny na rozci\u0105ganie po przeprowadzeniu obróbki cieplnej wynosi 1160 MPa. <\/div>\n

Hartowanie g\u0142ówki szyny zwi\u0119ksza jej twardo\u015b\u0107 i wytrzyma\u0142o\u015b\u0107 mechaniczn\u0105, wyd\u0142u\u017ca okres eksploatacji, powi\u0119ksza odporno\u015b\u0107 na zu\u017cycie, pomniejsza ryzyko wyst\u0119powania defektów szyny, poprawia odporno\u015b\u0107 na odpryskiwanie oraz pomniejsza koszty utrzymania torowiska.<\/div>\n
Podstawowym przedmiotem produkcji przedsi\u0119biorstwa DT s\u0105 zwrotnice i ich podzespo\u0142y. Do przyk\u0142adowych rozwi\u0105za\u0144 technicznych zaliczy\u0107 mo\u017cna system nastawczy DTZ. S\u0142u\u017cy on do automatycznego nastawiania zwrotnicy i znajduje zastosowanie dla szyn o rozstawie 1435 mm i pr\u0119dko\u015bci do 350 km\/h. Sterowanie jest realizowane mechaniczno-hydrauliczne, a awaryjnie równie\u017c r\u0119czne. Niezawodne, pewne zamki blokuj\u0105 zwrotnic\u0119 w nastawionym kierunku. Hydrauliczny nap\u0119d zwrotnicy umieszczony jest pomi\u0119dzy szynami. Energia z nap\u0119du kierowana jest do dwóch t\u0142oczków kieruj\u0105cych przesuwem iglic. Si\u0142a nastawcza jest p\u0142ynnie regulowana w szerokim zakresie. Po\u0142\u0105czenie pomi\u0119dzy opornic\u0105 a iglic\u0105 zapewnia specjalna rama. W wypadku uszkodzenia hydraulicznego uk\u0142adu sterowania, nastawianie zwrotnicy jest realizowane r\u0119cznie. Specjalne wzierniki pozwalaj\u0105 na kontrol\u0119 stanu zamków zwrotnicy. Modu\u0142owa budowa u\u0142atwia szybk\u0105 napraw\u0119 poprzez prost\u0105 wymian\u0119 uszkodzonych elementów. Powierzchnie przesuwu iglic s\u0105 samosmarowne, co eliminuje konieczno\u015b\u0107 okresowego smarowania. <\/div>\n
