The signal that pressure sensor (9051) are detected is converted into digital signal to pass to operation bench (2), and is shown by display screen (3)
Out, then by operation bench (2) control detection coil (12) it is powered, makes to generate a magnetic field in the first sensing chamber (4), work as casting
It is placed into when being connected with the detection coil (12) of alternating current nearby, the alternating magnetic field for being put into casting can generate direction in casting
It is mutually perpendicular to excitation field, forms the electric current of vortex shape flowing, vortex can generate the magnetic field contrary with excitation field, make
There is part reduction in former magnetic field in detection coil (12), so as to cause the variation of the impedance of detection coil (12), passes through display screen
(3) it is observed, detects defect existing for cast(ing) surface so as to the distortion that occurs according to the electrical feature of vortex；
S3: being opened while S2 is opened using operation bench (2) control X-ray device (5), will be electric by high pressure generator (501)
Pressure increases, and issues X-ray using the first X-ray head (504) and the second X-ray head (505) and is irradiated detection to casting, cooperates
Detection coil (12) work, can further enhance detection of the first sensing chamber (4) to casting surface defect, detection data passes through
Display screen (3) is shown, and is recorded data and compared；
S4: after S3 detection, casting is removed and placed on the second placement plate (10), the second sensing chamber is then fed into
(6) in, by operation bench (2) control magnetic coil (601) work, cooperate the use of temperature sensor (603), convenient for second
Temperature in sensing chamber (6) is controlled, then drives micro-machine (602) up and down adjustment by control hydraulic telescopic rod (604),
Micro-machine (602) are controlled simultaneously and drive hydraulic telescopic rod (604) rotation, are detected convenient for the surface to casting, Er Qiepei
The work of magnetic coil (601) is closed, conveniently at different temperatures, the variation of cast(ing) surface wearability is detected, finally records data
It compares, realizes and the surface progress wearability and heat resistance of casting are detected.
