Title: Method for measuring thickness of wall of refractories for furnace container
Inventor: FUKUOKA HIROMI
IPC: G01B7/06
Filed: 1982-11-04
Abstract: PURPOSE:To measure the remaining thickness of the wall of refractories accurately, by providing two coils on the inner wall of the refractories, which are lined on an iron skin with an interval being provided, and measuring the induced voltage in one coil when an AC voltage is applied to the other coil. CONSTITUTION:A transmitting coil 5 and a receiving coil 6 are contacted with the working surface of a wall 2 of refractories and arranged so that an iron skin and a sensor hold the wall of the refractories. An AC is conducted through the transmitting coil 5 from a high frequency generator 3 through a high frequency amplifier 4. Thus a primary magnetic field is generated. When the iron skin, which is a conductor, is present in the primary magnetic field, an eddy current is flowed in the iron skin by the electromagnetic induction, and a secondary magnetic field is generated accordingly. The intensity of the synthesized magnetic field of the secondary and primary magnetic fields is changed by the distance between the iron skin, which is the conductor, and the sensor. Therefore, the distance between the iron skin and the sensor, i.e., the thickness of the wall of the refractories, can be determined from the induced voltage in the receiving coil 6.
