内燃机车的投入生产,使我们接触到一些合金钢的锻造加工问题,这里想就在生产实际中体验到的提出来供兄弟单位参考。一、W_(18)Cr_4V高速钢的锻造。这种钢是含有钨和钒等合金元素的莱氏体组织,所以具有热硬性和高强度。其特点是:1.塑性较低,变形抗力很高,特别是铸态的高速钢更是如此。因此,应当以较小的压缩量来进行钢绽
The putting into operation of diesel locomotives makes us come into contact with the forging processing of some alloy steels, and we would like to refer to our brothers for the experience we have presented in the actual production. First, W_ (18) Cr_4V high-speed steel forging. This steel is a martensitic structure containing alloying elements such as tungsten and vanadium, so it has thermosetting properties and high strength. Its characteristics are: 1. Low plasticity, high deformation resistance, especially high-speed cast steel is even more so. Therefore, the steel should bloom with a smaller amount of compression
