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.
淬火钢轨由于其使用性能优越，目前已在运营线路上大量使用，并呈发展趋势。
The quenched rail laid on the track shows that the quenched rail with jetting air has better shelling resistance than that with mist cooling.
线路铺设使用也表明，喷风淬火钢轨比喷雾淬火钢轨具有更好的抗剥离性。
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.
本工艺有下述特点： 1。用煤气炉把钢轨整体加热，喷射水雾淬火，成本低，节约电能。
