摘要： The described embodiments relate to systems and methods for acoustic monitoring of metallurgical furnace cooling elements. Some metallurgical furnaces have a tapblock that is blocked during operation of the furnace. The tapblock may be opened by lancing, drilling, tapping or by other means to release metal from the furnace. By monitoring acoustic emissions during the opening process, feedback may be provided to improve the opening process and to avoid excessive damage to the tapblock, the cooling elements, a refractory lining of the tapblock or other elements of the metallurgical furnace.

摘要： Some embodiments of the present invention provide systems, methods and apparatus for more accurately determining the thickness of a refractory lining included in an operating metallurgical furnace. Specifically, in some embodiments a transient propagated stress wave is used to determine the condition of a refractory lining, and additionally, provide a systematic way to include the affect that temperature has on the velocity of a compressive wave through a heated refractory material and/or accretions. As identified in aspects of the present invention, and contrary to the common understanding in the art, the velocity of a stress wave, at each frequency and in a refractory material, is not necessarily constant over a temperature range. In accordance with aspects of some specific embodiments of the invention, a scaling factor α can be calculated for each refractory material to adjust for the presumed velocity of the stress wave through each refractory material.

摘要： A method for determining a length parameter of an electrode during operation of an electric arc furnace. An internal duct extends through the length of the electrode and is open at its lower end. A waveguide having a solid core is received in the internal duct and comprises a material having a low dielectric constant and high temperature resistance. The solid core of the waveguide includes at least one target. An electromagnetic radiation signal is emitted from a source and transmitted through the waveguide and the signal is diffracted and/or reflected from at least one target to produce at least one return signal which is transmitted back through the waveguide. A time or frequency difference between the emitted signal and the return signal is measured and the length parameter is calculated based on this difference.
