quenched rail

基本解釋

The superior properties of quenched rail have prompted its extensive use on operating railway tracks on an increasingly large scale.
淬火鋼軌由于其使用性能優(yōu)越，目前已在運(yùn)營線路上大量使用，并呈發(fā)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(shè)使用也表明，噴風(fēng)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(diǎn)： 1。用煤氣爐把鋼軌整體加熱，噴射水霧淬火，成本低，節(jié)約電能。
