    摘要: Apparatus and method is disclosed for on-line monitoring for early detection of diagonal distortion in a moving cast product ideally having a rectangular cross-section. A pair of contact rollers is supported on respective guide arms at a location along the casting path and biased to resiliently impinge on opposite edges of the moving cast product. A detector continuously senses the amount of separation between the contact elements to detect diagonal distortion in casting cross-section. A recorder is used to provide a tangible record of such variation. Optionally, both diagonals can be measured, and their sum or difference continuously monitored as well. A fixed support member carries the arms on slidable linear motion bearing structure to facilitate translational motion of the contact elements relative to the casting path, to minimize the effect of casting motion waver on contact separation.

    摘要: A force sensing control apparatus and method is disclosed for detecting forces which resist movement of a motor driven electrode system in an electric arc furnace. Force sensing circuitry monitors forces applied to an electrode system as it is positioned with respect to the furnace and force responsive controls inhibit electrode movement, hence preventing damage to the electrode or to its support structure, in response to predetermined changes in sensed reaction forces during positioning of the electrode. Compensating circuitry continuously compensates for changes in forces arising from electrode weight variations and position changes of the electrode support structure so that the sensitivity of the control apparatus to applied forces which can damage electrode system remains consistently high.

    摘要: The invention provides an electric-arc furnace electrode assembly having electrode sections of improved structural integrity. A pair of carbonaceous electrode sections are held securely in end-to-end relationship by a pin threaded into a pair of sockets found in the respective ends of the electrode sections. Harmful stress concentrations which occur near the base of the socket are reduced by providing a novel base portion. This is achieved by incorporating a generous radius of curvature intermediate the lower-most socket thread and the base of the socket. All of the socket threads are engaged and a threaded portion of the pin extends beyond the lowermost socket thread without engaging the base of the socket.
