摘要:
为了提高HFW钢管品质,高频焊接后需要对焊缝进行中频常化处理。针对中频处理后易造成焊管弯曲的现象,采用两台600 kW中频感应加热装置进行了在线焊缝模拟热处理,并对模拟结果进行了分析。分析表明,主要原因为中频温度和焊接速度等相关因素控制不好,焊缝温度高于管体温度,焊缝温度越高弯曲度越大。同时根据现场生产工艺提出了改进措施,即在空冷段增加冷却装置,以此来控制焊管进入水冷箱的温度,防止焊管弯曲度超标,收到了良好的效果。
Abstract:
In order to enhance HFW pipe quality, the intermediate frequency normalizing treatment is needed for weld after high frequency welding. Aimed at the phenomenon of welded pipe bending after intermediate frequency processing, using two 600 kW intermediate frequency induction heating equipment to simulate online weld heat treatment, and the simulation results were analyzed. The results indicated that some relevant factors are not under reasonable control, such as the intermediate frequency temperature, welding speed etc., which cause the weld temperature is higher than that of pipe body temperature. The higher of weld temperature, the higher of bending degree. Meanwhile the improved technology was put forward according to onsite production process, that is to say to increase cooling device in air cooling section, so as to control the temperature of welded pipe entering water cooling box, prevent excessive bending degree, and got good effects.
