一种钻杆焊缝热处理温度采集记录实现方法

Method for Acquiring and Recording Heat Treatment Temperature of Drill Pipe Welding Seam

在钻杆生产过程中焊缝热处理是极为重要的一道工序,该工序用来实现钻杆焊缝的热处理工艺,通过热处理使钻杆达到预期的强度;如果该工位没有热处理温度的采集和记录,对热处理工艺检查会造成很大困难,同时也不能保证加工工艺的实施,对钻杆质量和事故分析产生很大影响;经过现场调研研究,钻杆焊缝热处理工序增加温度采集和记录功能,可以实现温度监控和历史数据的追溯,对产品质量的保证和使用过程中产品问题的追溯具有重大意义;针对钻杆焊缝热处理的温度监控和数据的可追溯性问题,经过对温度信号的分析研究,提出使用PID调节器实现温度焊缝热处理温度的控制,同时采用PLC技术实现各个温度信号的采集和处理功能,结合WinCC和SQL-server实现温度信号的实时显示和数据记录,该方法很好的实现了钻杆焊缝热处理温度的采集和记录。

In the production process of the drill pipe,the heat treatment of the welding seam is a very important process.The process is used to realize the heat treatment process of the drill pipe welding seam,and the heat treatment is used to achieve the expected strength of the drill pipe.If the station does not collect and record the temperature of heat treatment will cause great difficulties in the heat treatment process of inspection,but also can’t guarantee the implementation process,have a great impact on the quality of drill pipe and accident analysis.After the scene investigation,the drill pipe weld heat treatment process to increase the temperature collecting and recording function,can realize the back temperature monitoring and historical data,is of great significance to ensure traceability of product problems and the use of the process on the quality of the products in the.According to the temperature monitoring and data of drill pipe weld heat treatment of the traceability problem,through analysis and study of the temperature signal,put forward using PID controller to realize the temperature control of the weld heat treatment temperature at the same time,realize the acquisition and processing function of each temperature signal by using PLC technology,combining WinCC and SQL-server to achieve the real-time display of temperature signal and data record,this method can realize the acquisition and recording of drill pipe welding heat treatment temperature.
