摘要
在对P92钢焊接热处理工艺实验的探索过程中,发现了有效降低厚壁管道在热处理过程中内、外壁温差的方法。以此进行了大量实验,并对实验结果进行了总结,为现场厚壁P92管道热处理工艺的探索提供了一个全新的思路。
During the experimentation of steel welding heat treatment techniques of P92,the method of effectively lowering the temperature difference between the inner and outer walls of a thick-walled pipe was discovered.Many experiments were conducted based on this discovery.After concluding the results of these experiments,a new approach was discovered for exploring onsite thick-walled P92 pipe＇s heat treatment.
