Abstract: An aluminum reduction cell having a shell structure with a pair of longitudinally extending sidewalls, a pair of transversely extending endwalls, a bottom wall, and an open top having an upper edge. The aluminum reduction cell also has a transverse support structure with transverse bottom beams located under the shell structure and extending transversely between the sidewalls, each of the transverse bottom beams having a pair of opposed ends. The aluminium reduction cell also has compliant binding elements fixed to the transverse support structure, each extending vertically along an outer surface of one of the sidewalls for applying an inwardly directed force said sidewall. The compliant binding elements are in the form of cantilever springs. Each spring has a metal member with a lower end which is secured to the transverse support structure, and a compliant, upper free end which is movable inwardly and outwardly in response to expansion and contraction of the shell structure.

Abstract: 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.

Abstract: 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 methods 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.
