Abstract
A method of determining the friction between the strand shell and the mold during continuous casting with an oscillating mold includes measuring with the use of controlled double-acting hydraulic cylinders and with a predeterminable measuring frequency the pressures of always both chambers of all oscillating cylinders as well as the lifting positions of the pistons corresponding to these pressures, and by computing from these data the friction force acting at any point in time between the strand shell and the mold walls.

A method of determining a friction force between a strand shell and walls of a mold during continuous casting by means of an oscillating mold using controlled double-acting hydraulic oscillating cylinders for oscillating the mold, the method comprising measuring the pressures of always both chambers of all the oscillating cylinders as well as lifting positions of the pistons corresponding to the pressures with a predeterminable measuring frequency, and computing from the resulting data the friction force acting at any given time between the strand shell and the walls of the mold.
