无缝钢管的穿孔过程是一个热加工过程 ,顶头的温度分布对于其寿命至关重要。应用热电偶埋入顶头的测量办法对顶头在生产过程的温度分布进行了实测。初步得到其温度的分布状况 ,为顶头的热处理提供依据
The perforation process of seamless steel pipe is a hot working process, and the head temperature distribution is crucial to its life. The thermocouple embedded in the head measurement method was used to measure the temperature distribution of the head in the production process. Preliminary temperature distribution, provide the basis for the head heat treatment
