    • A method of continuously casting metal strip for a twin roll caster may include steps of sensing images of a casting pool in the casting area indicative of the casting pool depth, displaying the sensed images to an operator, and controlling a flow of molten metal from a metal supply system into the casting pool responsive to the sensed images indicative of the casting pool depth. The method may include producing separate electrical signals corresponding to the sensed images and controlling the flow of molten metal from the metal supply system into the casting pool responsive to one or more of the electrical signals. The electrical signals may be processed to determine the casting pool depth in each of the plurality of locations and the casting pool depth displayed to the operator. One or a combination of the electrical signals may be selected for providing a determined casting pool depth, and the flow of molten metal may be controlled responsive to the determined casting pool depth. The determined casting pool depth may be an average of casting pool depths from the selected electrical signals.

    • The invention relates to a sequential casting method for the production of a high-purity cast metal billet (13) from a metal melt, wherein the metal melt is supplied from a melt container (5) in a controlled manner to a distributor vessel (8) and is then supplied from said distributor vessel (8) in a controlled manner into a continuous casting ingot mold (4) without any interruption. According to the invention, in order to cast a qualitatively high-value metal billet even when the melt vessel is changed and to ensure that the restart phase is kept as short as possible, the flow rate into the distributor vessel is greater than the outflow rate from the distributor vessel during a period of time ranging from the resumption of the supply of the metal melt to the distributor vessel until a quasi-stationary operating bath level height is obtained in the distributor vessel (8), wherein during 70 % - 100 % of said time period, the inflow rate into the distributor vessel (8) is less than or equal to twice the outflow rate from the distributor vessel.
