Molten metal poured into a mold region, delimited by a first casting roll that rotates about a first rotational axis, produces a metal strand upon solidification which is conveyed out of the mold region. A liquid coolant is applied to the surface of the first casting roll by a first cooling device via first coolant lines and first coolant applying devices. The coolant is inert with respect to the molten metal and has a standard boiling point below 20&#xb0; C., e.g., &#x2212;20&#xb0; C., at normal air pressure, and an operating temperature at or below an operating boiling point at an operating pressure at which the coolant is supplied. A control device automatically controls the first cooling device by ascertaining a control state of the first cooling device using a target property for an actual property of the first casting roll or the metal strand detected by at least one sensor.
