Abstract

A találmány tárgya eljárás sínek vagy legalább a sínfejekkeményítésére, azok gyorsított lehűtésével, és az ausztenitesszövetszerkezetnek kívánt szobahőmérsékleten stabil mikrostruktúráravaló átalakítására. A találmány szerinti eljárást az jellemzi, hogy azausztenites szövetszerkezetű sínt (1) rendezik, vízszintesenpozicionálják és elhajlás ellen biztosítottan tengelyiránybanmegfeszítik, majd a feszítés illetve a hajlítás elleni biztosításfenntartásával a sínt (1) és/vagy legalább a sínkeresztmetszet egyrészét egy bizonyos hőmérsékletről, amely az ötvözet Ac3 pontja feletthelyezkedik el, önmagában ismert módon legalább időnként hűtik ésezzel a szövetszerkezetet megváltoztatják. A találmány tárgya továbbáberendezés sínek vagy legalább a sínfejek edzésére, azok gyorsítottlehűtésével, az ausztenites szövetszerkezetnek a kívántszobahőmérsékleten stabil mikrostruktúrára való átalakítására, amelylényegében egy síntámasztóból és egy hűtőgépből áll. A találmányszerinti berendezést az jellemzi, hogy a síntámaszték minttartószerkezet (2) van kialakítva a sín (1) hosszirányú kiterjedésementén és nagy hajlító ellenállással, valamint pozicionáló elemekkel(3) és/vagy oldható feszítőelemekkel (4) van a sín rögzítéséreellátva.
