摘要: A technical problem to be solved by the present invention is to provide a mounting device capable of smoothly mounting a drive unit being in a hanging state to a sliding nozzle device, using a manipulator. The present invention provides a mounting device 4 mounted to a distal end of a manipulator 4 to mount a drive unit 31b whose upper end is connected to a suspending device, to a holder 36 of a sliding nozzle device 3. The mounting device 5 comprises: a holding part 52 for holding an upper portion or central portion (to-be-held plate 313) of the drive unit 31b; and a contact part 55c which is contactable with a lower portion (to-be-contacted part 314) of the drive unit 31b when mounting the drive unit 31b to the holder.

摘要: Verfahren zur Herstellung eines optimierten Kühlraums in einem Werkzeug bzw. Werkzeugeinsatz zum Giessen von Metallteilen mit folgenden Schritten:
• Erstellen eines dreidimensionalen Modells eines Werkzeugs bzw. Werkzeugeinsatzes,
• Auslegen eines Kühlraums im Werkzeug bzw. Werkzeugeinsatz,
• Auslegen einer Giessform entsprechend dem Werkzeug bzw. Werkzeugeinsatz,
• Erstellen eines Kerns entsprechend des ausgelegten Kühlraums,
• Erstellen der Giessform,
• Abgiessen des Werkzeugs bzw. Werkzeugeinsatzes mit in die Giessform eingelegtem Kern zum Erzeugen des Kühlraums,
• wobei eine optimierte Kontur des Kühlraums (5) mittels eines Strömungssimulationsprogramms zur Simulation der Strömung des Kühlmittels und mittels eines Wärmeübertragungssimulationstools, welche den Wärmeverlauf im Werkzeug bzw. Werkzeugeinsatz beim Giessen simuliert, ausgelegt wird.-

摘要: The present disclosure addresses the technical problem of prediction of a preheat refractory temperature profile of a ladle furnace. Operational temperature of the ladle furnace, stability of sensors and placement make sensors not feasible. Computational Fluid Dynamics (CFD) simulations require large computation time and cannot be used for runtime applications in plants. The method and system of the present disclosure uses CFD modeling to carry out parametric study to generate data which is further processed to train an Artificial Neural Network (ANN) model that serves as a prediction model for predicting the preheat refractory temperature profile for at least a portion of the side refractory and at least a portion of the bottom refractory layer separately for which a new set of input data is obtained. The trained prediction model of the present disclosure provides a quick runtime prediction in plants.
