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 a method for optimizing the cooling capacity of a continuous casting mold (1) for liquid metals, particularly for liquid steel, by homogenizing the thermal load (22) above the height of the continuous casting mold (1). According to the method, the cooling medium (5) is guided through a cross-sectional area of a large number of cooling medium channels (3) or cooling medium boreholes (4) running approximately parallel to the cast billet (9). The cooling medium cross-sectional areas between the mold entry (6) and the mold exit (7) are configured differently. In order to homogenize the thermal mold load (22), a smaller cross-sectional area sets the flow rate of the cooling medium (5), which is conducted from the top downward, inside the cooling medium channel (3) or inside the cooling medium borehole (4) higher in the upper area of the continuous casting mold (1) than in the lower area of the continuous casting mold (1) in which the flow rate is set lower by a larger cross-sectional area and/or the covering of the cooling medium is adjusted by a cross-sectional shape that varies from the top downward.

Abstract: Disclosed are a method and a device for continuously casting billets (1), among others, which are made of liquid metals, particularly steel materials. According to the invention, heat is removed in a primary cooling zone (4), further cooling taking place in a secondary cooling zone (7) with the aid of a dynamic spraying system (6) by means of nozzles (8) that impinge the width (9) and the metallurgical length (10a) of the billet while the heat distribution is determined and the surface temperature is measured by temporarily sampling the billet surface. The aim of the invention is to obtain a temperature curve which is advantageous for further processing across the entire cross section of the billet. Said aim is achieved by the fact that the dynamic spraying system (6) is functionally controlled in the form of the distribution of the water quantity and the pressure distribution or pulse distribution across the width (9) and length (10a) of the billet via the discharge temperature which is determined by verifying the surface temperature at the end (10b) of the metallurgical length (10a) of the billet so as to obtain a temperature curve (20) calculated for the billet length (10a) and/or the billet width (9).

Abstract: The invention relates to a method and device for continuously casting metal, particularly steel, whereby molten metal (6.1) is continuously cast in a cooled ingot mold with a casting speed (3) while forming a meniscus (7), and a cast product is continuously drawn out of the ingot mold in a direction of casting (3.1). The ingot mold, which has an ingot mold inlet (12) and an ingot mold outlet (8), is a water-cooled copper ingot mold having ingot mold cooling water channels (10.4) with a channel inlet and a channel outlet through which cooling water flows. Said water has an entry pressure p0 (15) at the channel inlet and an exit pressure p1 (15.1) at the channel outlet. The inventive method and device should be improved as to impede or prevent the high thermal load T of the ingot mold in the meniscus. To this end, the invention provides that, during a controlled adjustment of the water flow speeds in the ingot mold cooling water channels (10.4) and during a monitoring of the pressure loss DELTA p of the cooling water, the cooling water direction of flow (12) should correspond to the direction of continuous casting while forming a Nusselt layer that, at the height of the meniscus (19.1), is thinner than the Nusselt layer at the ingot mold outlet (19.2).

Abstract: Initial temperature of melt in the distributor (302) is measured at a first casting speed. The first heat loss rate is measured from melt in the distributor, and also during its residence time between distributor and the casting level in the casting mold. An equivalent liquidus temperature T'liq + 0 is determined as the limiting temperature which will be reached, taking into account the initial liquidus temperature Tliq of melt already in the casting region of the mold, and the given casting speed. Isotherms of the equivalent liquidus temperature T'liq + x are determined as a function of superheating temperatures x, with x greater than zero, the isotherms each relating melting temperatures in the distributor and casting speeds. The initial continuous casting speed is matched to a desired continuous casting speed inside a given window of isotherms, with the lowest boundary lying above the equivalent liquidus temperature curve T'liq + 0. An Independent claim is included for the corresponding casting system.
