    Abstract: PROBLEM TO BE SOLVED: To improve a mold or continuous casting operation in a continuous casting method and its apparatus. SOLUTION: In a thermal control method for a copper plate facing to steel of a continuous casting mold regarding different casting speeds, different copper plate thickness, different casting sizes, different water amount and different water pressure respectively, the method is characterized in that selectable mold cooling water temperature at an outlet of the mold is constantly maintained unrelated to a casting speed. Temperature of the outlet of the mold is measured and controlled by a two way type valve having a short pipe between the outlet of the mold and an inlet of the mold and a bifurcated pipe providing for partial amount of the cooling water from the outlet of the mold to a heat exchanger. Hot cooling water at the outlet of the mold is mixed with cooled water at the outlet of the mold, and cooling water amount and pressure of at the outlet of the mold, in which cooling water temperature is controlled dependent on casting condition, is also controlled. Then, molding cooling water at the outlet of the mold is circulated through the mold by a pump station so as to maintain constant temperature.

    Abstract: The invention relates to an automatic start method for continuous casting systems, preferably for strand thicknesses of 10 -150 mm and widths of up to 3.500 mm by regulating the casting level and by means of a closure system consisting of a slider system or a stopper system. In order to automatically start the continuous casting system, the following process data is detected: the temperature of the steel at the end of the treatment thereof in the secondary metallurgic range, T.LF (11); the heating-up time of the distributor before casting begins, t.T (5.1); the inner distributor temperature after the distributor has been pre-heated, W.T (14), T.T (4); the weight of the steel in the distributor at the moment when the distributor is opened for casting to begin; the time required to fill the permanent mold, the time between the moment the permanent mold is opened and the strand (15) is removed; formation of a functional context for the product of T.LF (11), t.T (5.1), W.T (14), for example; formation of the functional relationship between filling time (15) and the product from ((11) (5.1) (14)); establishment of the desired filling time (15) for all successive castings and determination of the weight of the steel in the distributor equivalent to the desired filling time when the temperature of the steel T.LF (11) is set in an uncontrolled manner; pre-heating time of the distributor t.T (5) and distributor temperature T.T (4) directly before the kettle is opened in order to fill the distributor.
