Abstract (en)

Process for continuously controlling the base adjustment and oscillating parameters of a continuous casting mold arranged in an elevating platform (10) comprises operating the platform using four corner, preferably double-acting hydraulic cylinders (2-5) in oscillations, and measuring the oscillating forces acting on the hydraulic cylinders during a casting pause or during the casting operation. An Independent claim is also included for an apparatus for carrying out the process comprising hydraulic cylinders (2-5) each having a piston (9) between two chambers (7, 8) with a hydraulic valve (13) controlling the pressure chambers. A pressure differential calculator (14) determines the effective resulting force of the hydraulic cylinder. A position transmitter (15) is connected to the cylinder.

Abstract (de)

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur kontinuierlichen Kontrolle der Grundeinstellung und der Oszillationsparameter einer in einem Hubtisch 10 angeordneten Kokille. Verfahren und Vorrichtung werden dadurch verbessert, daß der Hubtisch 10 der Stranggießkokille 1 von vier eckständigen, vorzugsweise doppeltwirkenden Hydraulikzylindern 2 - 5 in Schwingungen angetrieben wird und die an den Hydraulikzylindern tatsächlich wirkenden Oszillationskräfte in Gießpause und/oder Gießbetrieb meßtechnisch erfaßt und zur Diagnose der Gießmaschine und/oder des Gießprozesses verwendet werden. <IMAGE>
