圓鋼退磁：
Round steel demagnetization：
零部件經過加工和探傷后會殘留磁場，直接影響加工和使用，所以必須要進行退磁。工件表面的磁場性質和工件特定的環境有很大關系，不是所有的磁場都是一個特性，分直流磁場、交流磁場、不規則磁場等，必須要針對磁場特性選擇不同退磁方法，直流一般要選用直流專用退磁，交流選擇交流退磁方法，我們為您提供各種不同的退磁設備。
Parts will remain magnetic field after processing and flaw detection, directly affecting processing and use, so demagnetization is necessary. The nature of the magnetic field on the surface of the workpiece has a great relationship with the specific environment of the workpiece. Not all magnetic fields are a characteristic. They are divided into direct current magnetic field, alternating current magnetic field and irregular magnetic field. Different demagnetization methods must be selected according to the characteristics of the magnetic field. Direct current usually uses direct current special demagnetization method, alternating current demagnetization method. We provide you with various demagnetization equipment.
