本文论述了控制加热规范、锻造温度范围和采用弧形砧以改变锻件受力状态,以及锻后水冷等等措施,对防止锻造开裂,提高锻件合格率所起的作用。在此基础上,本文还进一步研究了施行高温形变热处理工艺,以提高材料高温机械性能,从而提高排气阀的使用寿命所起的效果,我们认为,以上种种措施,对简化工艺和设备、减轻劳动强度,具有显著的效益,值得在生产中推广。 This article discusses the control of heating specifications, forging temperature range and the use of arc anvil to change the force status of forgings, as well as forging water cooling and other measures to prevent forging cracking and improve the pass rate forging role. On this basis, this paper further studies the effect of high temperature deformation heat treatment process to improve the high temperature mechanical properties of the material, thereby improving the service life of the exhaust valve, we believe that the above measures to simplify the process and equipment, reduce Labor intensity, with significant benefits, it is worth promoting in production.
