Abstract | The invention discloses a furnace tube carburized layer thickness evaluation method and system based on a magnetic field disturbance and magnetic force dual-detection ring. Two principles of magneticfield disturbance and magnetic force detection are adopted, and the system is composed of an upper computer, a main control box, a magnetic field disturbance circular ring array sensor, a magnetic force detection circular ring array, a crawler-type pipeline climbing device and the like, and can be used for evaluating the thickness of the an inner wall carburized layer of an ethylene cracking furnace tube. In the process that the crawler-type pipeline climbing device carries the magnetic field disturbance circular ring array sensor and the magnetic force detection circular ring array to climb and advance along a furnace tube, and a Hall element of a magnetic field disturbance sensor unit detects the magnetic field intensity of the surface of the furnace tube in the bus direction so as to reflect the magnetic field |
