The device further includes a cooling unit for the containment structure including a cooling channel for passage of a liquid medium therein, and an ultrasonic probe disposed in relation to the cooling channel such that ultrasonic waves are coupled through the liquid medium in the cooling channel and through the molten metal containment structure into the molten metal.

A method for operating a combined casting/rolling installation: A casting machine (4) of the combined installation (2) produces a cast product (40) and a rolling mill (6, 8) of the installation (2) produces a rolled product (42a, 42b) from the cast product (40). The installation (2) has a control device (12) with a measuring unit (14) and a controller (16). The measuring unit (14) detects a rolled-product property, generates a measurement signal dependent on that property and transmits the measurement signal to the controller (16), and the controller (16) uses the measurement signal to generate a control signal for the casting machine (4) based on a control algorithm and transmits the control signal to the casting machine (4) which uses the control signal to set a casting parameter. The detected rolled-product property is a temperature profile of the rolled product (42a, 42b) in the width direction thereof and the casting parameter that is set by the casting machine (4) using the control signal is a cooling parameter of the casting machine (4).
