低碳钢磁性热处理影响因素的实验研究与讨论

Experimental Study and Discussion on Influencing Factors of Magnetic Heat Treatment of Low Carbon Steel

针对低碳钢磁性热处理理论,提出了新观点,认为在奥氏体区高温长时间保温对低碳钢磁性能影响不大,起关键作用的是两相区相变过程。根据新观点制订了新工艺,并通过实验验证了该观点的正确性。结果表明,新工艺时间只有原工艺时间的1/2,而磁性能仍保持与原工艺基本相同的水平。

A new viewpoint was put forward for the magnetic heat treatment theory of low carbon steel.It was considered that heat preservation with high temperature for a long time in the austenite region has little effect on the magnetic properties of low carbon steel,and the phase transformation process in the two-phase region was the key.According to the new point of view,a new process was put forword,and the correctness of the viewpoint was confirmed by the experiments.The results show that the new process time is only 1/2 of the original process time,while the magnetic properties remain basically the same level as the original process.
