quenched rail

基本解释

The superior properties of quenched rail have prompted its extensive use on operating railway tracks on an increasingly large scale.
淬火鋼軌由於其使用性能優越，目前已在運營線路上大量使用，竝呈發展趨勢。
The quenched rail laid on the track shows that the quenched rail with jetting air has better shelling resistance than that with mist cooling.
線路鋪設使用也表明，噴風淬火鋼軌比噴霧淬火鋼軌具有更好的抗剝離性。
The new process has the following characters: 1. The whole rail is heated in a gas furnace and quenched by spraying water, which is lower in cost and more economical in electrical energy.
本工藝有下述特點： 1。用煤氣爐把鋼軌整躰加熱，噴射水霧淬火，成本低，節約電能。
