采用工艺试验方法,研究了推盘炉生产线渗碳淬火的质量控制。结果表明,对于比较小的齿轮或齿轮轴,可检测随炉试棒,对于比较大的齿轮,试棒与试块的检测结果不能代替工件的处理结果时,需解剖工件检测。经过一年多的实际生产验证,这种方法既保证渗碳淬火热处理质量又兼顾检测成本,其产出与投入比较高。 The technological test method was used to study the quality control of carburizing and quenching in the production line of push-plate furnace. The results show that for smaller gears or gear shafts, the test bars can be tested with the furnace. In the case of relatively large gears, the test results of the test bars and test blocks can not replace the treatment results of the workpieces, and the workpiece inspection is required. After more than a year of actual production verification, this method not only guarantees the quality of carburizing and quenching heat treatment, but also takes into account the testing costs, and its output and input is relatively high.
