Coil-only type electromagnetic ultrasonic probe for high-temperature casting and forging and detection device

The utility model discloses a coil-only type electromagnetic ultrasonic probe and a coil-only type electromagnetic ultrasonic device for high-temperature casting and forging pieces. The corundum sheet is arranged at the bottom of the probe shell; the coil is arranged in the probe shell and is positioned above the corundum sheet; the interface is arranged on the probe shell and is electrically connected with the coil; and a high-temperature-resistant ceramic adhesive is filled in a cavity formed by the probe shell and the corundum sheet. The coil-only type electromagnetic ultrasonic probe abandons a permanent magnet and an electromagnet, is only composed of a single coil, is smaller in size, is more beneficial to detection of a narrow area, is high in transduction efficiency, is not liable to adsorb ferromagnetic particles to cause reduction of the transduction efficiency or even functional damage of the probe, and is easy to separate from or move from a ferromagnetic metal material. And the device can continu
