Abstract

Procedeul de prelucrare termică a şinelor, în special a capului şinei, în care răcirea se realizează într-un răcitor, care conţine un adaos răcitor sintetic, începând cu o temperatură mai mare de 720°C, prevede cufundarea, care se efectuează până când după extragerea zonelor cufundate suprafaţa lor are o temperatură de la 450 până la 550°C, fără nivelarea temperaturii pe toată secţiunea transversală, pentru ca după respectarea vitezelor optime de răcire a capului şinei să se poată evita ridicarea durităţii inimii şinei.
