摘要
介绍了利用中频感应加热原理对地质钻杆进行整体热处理工艺,并通过对比数据分析了中频感应热处理技术比普通热处理技术所具有的优点。分析结果表明,相对于采用普通热处理,采用中频感应加热进行热处理的地质钻杆,金属显微组织晶粒细,综合机械性能好,钻杆性能更均匀,钻杆表面氧化很少,外观质量好,抗疲劳性能高,生产成本低。
The paper introduces the principle of medium-frequency induction heating in geological drilling pipe with whole heat treatment,and analyzed the advantages of medium-frequency induction heating technology.The analysis shows that comparing to ordinary heat treatment technology,the drilling pipe treated by medium-frequency induction heating has fine metal microstructure of grain,good mechanical properties,even drilling performance,less surface oxidization,good appearance quality,high anti-fatigue performance and low production cost.
