  • Product overview

Hardness sorting principle: because the hardness value of magnetic conductive materials, material varieties, hardening layer depth, heat treatment state, parts of the defects (such as cracks, pores, inclusion, etc.) have different effects on the magnetic field, and there is a certain corresponding relationship. When the measured workpiece is in contact with the uniformly distributed probe magnetic field, the amount of magnetic field in the probe changes, the probe coil produces an exciting current, and is transmitted to the instrument through the wire. After the analysis and processing of the instrument's central circuit, the quality of the measured workpiece can be automatically discriminated through computer software processing and displayed on the display screen. It is with the help of the measured workpiece magnetic flux caused by the change of the electromagnetic effect of the electrical signal, after amplification and conversion after computer software processing, to achieve the material composition, hardness, surface hardening layer depth, crack, mixing and other defects detection.


Technical parameters: hardness detection sensitivity: Rockwell: ±2HRC; Vickers: ± 40HV. Range of error: effective separation of different materials

影像、探傷、尺寸綜合檢測機

磁粉探傷機之探傷的插電、焊接及其磁痕常見問題:

一、插電:

1、應用不斷法磁化時要確立插電時間必須保證 磁粉探傷能在插電狀況下應用進行;

2、應用磁損法磁化時,磁化時間一般是0.2-1s,利用沖擊性電流量時要在十米s之上,持續插電2次之上。假如磁粉探傷機在探傷情況下能有充裕的磁勢那麼就可以不依照這一要求的管束。

二、焊接

1、一個是在電焊焊接后要對焊接執行熱處理工藝時,就需要在熱處理后執行探傷。

2、對熱處理后的間隙和高壓容器的探傷,其磁化方法不必利用立即通電流量的方法。

針對磁粉探傷機測試中產生的磁痕,假如十分難分辨真偽時,就需要對其開展去磁。

三、磁痕

1、如果是磁寫的磁痕,去磁后再度測試,磁痕就會沒有。

2、因為磁粉探傷機探傷面凸凹不平而造成的磁痕,可把探傷面磨滑后再執行檢測,探傷檢測設備的磁痕就會消退。

3、因為超聲波探傷無損檢測強電流量造成磁粉探傷匯聚而出現偽磁痕,可降低電流量或利用磁損法再度檢測,磁痕就會消退。

4、對產生在導磁率突然變化部位的磁痕,能夠利用宏觀經濟檢驗,光學顯微鏡查詢等磁粉探傷探傷以外的方法來鑒別。
