    Abstract: The invention relates to a device for cooling the copper plates (1.1) of a continuous casting ingot mould (1) for liquid metals, especially liquid steel, comprising an ingot mould coolant (2) which is guided in cooling channels. During the initial temperature rise to achieve a set casting speed or when said casting speed is exceeded for a deviating copper plate skin temperature (8), the copper plate skin temperature (8) is influenced, even when the casting speed is higher, in such a way that surface errors in the casting shell and/or cracks in the surface of the copper plates are prevented from occurring or occur in a significantly reduced manner by adjusting the copper plate skin temperature (8) at alternating casting speeds (6) of between 1 m/min and a maximum 12 m/min by means of quantitative correction of the amount of ingot mould coolant (4) and/or ingot mould coolant inflow temperature (5) according to the casting speed (6) and according to the thickness of the copper plates (9), to a desired constant value.

    Abstract: Procedimiento para controlar el caldo en una máquina de colada en cuerda, vertiéndose el caldo de una determinada aleación a una temperatura de líquidus Tliq, a través de un distribuidor (2, 102, 202, 302), en un molde de colada (4, 104, 214, 215) y extrayéndose la cuerda (314) solidificada en el interior del molde de colada, caracterizado por detección de la temperatura real del caldo en el distribuidor a una velocidad de colada real, establecimiento de la pérdida de calor real del caldo en el distribuidor y durante su tiempo de retención entre el distribuidor y el espejo de colada (9) en el molde de colada, establecimiento de una temperatura de líquidus equivalente T*liq + 0 (15) como temperatura límite para la temperatura del caldo en el distribuidor, a la que ya en el margen del espejo de colada del molde de colada se alcanza la temperatura de líquidus Tliq a una velocidad de colada dada, así como las isotermas de la temperatura de líquidus equivalente T*liq + x en dependencia de temperaturas de sobrecalentamiento x con x>0, las isotermas en cada caso en relación con las temperaturas de fusión en el distribuidor y las velocidades de colada, adaptación de la velocidad de colada real de la cuerda a una velocidad de colada nominal de la cuerda dentro de una ventana de isotermas prefijada, cuyo límite inferior está situado por encima del desarrollo de la temperatura de líquidus equivalente T*liq + 0.

    Abstract: The invention relates to a method, which is used in the area of secondary metallurgy (4) in its entirety with a final temperature-determining process step (4.1) such as a ladle furnace, for controlling the temperature of steel from the surface of the bath of a continuous casting ingot mold (1) up to the furnace tap (5) of a steel producing process. According to the invention, the temperature of the steel in the surface of the bath is controlled based on the equation TML = TLI + X DEG C (X = 5 - 15 DEG C) and while respecting the same such that a jump in temperature (9) between the surface of the bath in the ingot mold (1) and a distributor (3) is detected according to the pouring rate (6) for a predetermined billet size. In addition, the ladle history (7) with regard to the time intervals, such as ladle full , ladle empty and ladle state, such as ladle bricking up and ladle age is detected as well as a jump in the temperature of steel between the distributor (3) and the last ladle furnace temperature (LF-ex).
