一、项目的意义和背景某大型公司叶片分厂高频炉用于叶片司太立合金焊接,公司所有末级和次末级叶片均要焊接司太立合金,以增加叶片强度,其中对百万千瓦等级核电汽轮机叶片、百万千瓦等级超临界汽轮机机组叶片,意义尤其重大。司太立合金焊接,以金属银锰合金为焊料,要求焊料温度均匀,才能保证焊接质量,保证叶片强度,因此需对整个焊片的温度及温场分布监测。公司原有光电高温计是点温测量装置,只能检测一点的温度,无法对焊接的温度场进行分析,肉眼观
First, the project’s significance and background A large company leaves the high-frequency furnace plant for the blade Secretary Stellite welding, the company all the last and second-and-last-stage blades must be Welding Secretary Stellite to increase the strength of the leaves, of which hundreds Ten thousand kilowatt-class nuclear turbine blades, one million kilowatts grade supercritical turbine blades, the significance is particularly significant. Stellite alloy welding to metal silver-manganese alloy solder, solders require uniform temperature, in order to ensure the quality of welding, to ensure the strength of the blade, so the entire solder piece temperature and temperature distribution monitoring. The company’s original photoelectric pyrometer is a point temperature measurement device that can only detect a little temperature, the temperature field of welding can not be analyzed, the naked eye
