Method and system for operating a high-speed continuous casting plant

System provided in a high-speed continuous casting plant for casting a metallic strand (1.7) in particular a slab, with casting speeds of maximally .10 m/min., the system comprising an oscillating casting mold (1) which comprises oppositely positioned casting mold narrows sides (1.2.1, 1.2.2) and faces (1.3.1, 1.3.2), in particular comprised of copper plates, which can be controlled during casting by means of adjusting cylinders (1.2.3) with regard to their conicity, wherein molten mass flows via a submerged exit nozzle (1.5) or a nozzle from a distributor (6) into the casting mold (1) and

• the distributor (6) has a movable stopper (6.1) or a slide closure for regulating the in flowing molten mass quantity, optionally employing casting powder (1.6),
• comprising means for measuring the meniscus movement (9),
• a continuous or discontinuous measuring device for measuring the melting temperature in the distributor (6.2),
• comprising means for measuring the actual casting speed (1.8) of the strand, in particular, the slab,
• as well as a computing unit (10) for determining the changes of the casting process over a predetermined casting time interval as well as for comparing the changes with predetermined limits (10.1),
• further comprising means for measuring the stopper or slide closure movement (6.1.1),
• means for measuring the face heat flow (7) of the fixed side and the loose side,
• means for measuring the narrow side heat flows (8) of the operating side and the drive side,
• means (1.2.3) for changing the angular position of the conically arranged two narrow sides of the casting mold as well as means for changing the casting speed,
• wherein the means for changing the angular position of the narrow sides as well as the means for changing the casting speed can be automatically controlled as a function of the result of the computing unit (10) or can be controlled semi-automatically.
