热处理工件的加热时間应該包含两个方面的內容,即工件加热到溫度时間和完成組織轉变时間(包括均匀化)。前者实际上是一个加热速度問題,后者是相变热力学問題,本文想从盐浴炉和空气炉两类基本情况入手,突破传統的框框,探討重新規定热处理件淬火加热时間的方案。 Heat treatment of the workpiece heating time should include two aspects, namely, the workpiece is heated to the temperature and the time to complete the organization change (including homogenization). The former is actually a heating rate problem, the latter is the phase transition thermodynamic problems. This article from the salt bath furnace and air furnace two basic conditions to start, breaking the traditional box to discuss re-regulation of heat treatment quenching heating time program.
