Systems, methods and apparatus for inspection without interruption and without destruction of metallurgical furnaces and similar containers

摘要

An apparatus for inspecting a metallurgical furnace wall (31, 33, 35) comprising: a plurality of pairs (73a-73d) of impact-driven voltage wave generator-sensor, each pair for generating a P wave and reflections of P wave detection at the point in a metallurgical furnace; characterized in that a processor (78) comprises a program code which, when executed by the processor, causes the processor to produce a determination of the condition of the metallurgical kiln wall using time domain data collected by at least one sensor, frequency domain data derived from time domain data, and a temperature-dependent rate scaling factor to correct the change in the velocity of the P wave and the reflections of the P wave through a material (33 , 35) refractory included in the furnace metallurgical wall.
