Title:
Cu STAVE ABRASION DETECTION SENSOR
Document Type and Number:
Japanese Patent JP2023064567
Kind Code:
A
Abstract:
To provide an abrasion detection sensor capable of accurately measuring progress of abrasion of a Cu stave over a long period of time even at a site where a temperature level is extremely high and a temperature fluctuation is sharp in a furnace.SOLUTION: An electric circuit 2 whose electrical characteristics are caused to change by damage and disconnection due to abrasion of a Cu stave is housed in a sensor body 3, a plurality of lead wire units 4 having detection lead wires 40 that cause the change in electrical characteristics are arranged so as to extend to different positions in a length direction of a tip side member 30 of the sensor body 3, and the detection lead wires are connected in series with resistors as detection elements constituting the electric circuit 2, and sets of each detection lead wire and each resistor are connected in parallel with each other. The tip side member 30 consists of a rod-shaped body made of Cu or Cu alloy solid material, a plurality of housing holes 33 are provided to individually house the lead wire units 4, and the lead wire units 4 are housed inside the housing holes 33.SELECTED DRAWING: Figure 2
