HP型制氢炉炉管的组织劣化程度监测方法及装置
摘要：
本发明提供了一种HP型制氢炉炉管的组织劣化程度监测方法及装置，涉及石油炼油技术领域，所述方法包括：根据预先设置的监测时间定时获取HP型制氢炉炉管的金相组织图片；将所述金相组织图片与预先存储的样本图片进行比对，确定所述金相组织图片对应的HP型制氢炉炉管的组织劣化程度；根据所述组织劣化程度确定所述HP型制氢炉炉管的剩余使用寿命。本发明能够解决当前对一个较长周期的炉管损伤状态无法及时跟踪，且难以确定炉管的剩余寿命的问题。
摘要（英）：

The invention provides a method and a device for monitoring the structure deterioration degree of a furnace tube of an HP-type hydrogen manufacturing furnace, and relates to the technical field of petroleum refining. The method comprises the steps of timely obtaining metallographic structure images of the furnace tube of the HP-type hydrogen manufacturing furnace according to the preset monitoring time; comparing the obtained metallographic structure images with pre-stored sample images to determine the structure deterioration degree of a furnace tube of an HP-type hydrogen manufacturing furnace corresponding to the metallographic structure images; and determining the rest service life of the furnace tube of the HP-type hydrogen manufacturing furnace according to the structure deterioration degree. The invention can solve the problems that the damage state of a furnace tube used for a longer period cannot be traced immediately and the rest service life of the furnace tube is difficult to determine.
