    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: Oscillating mould intended for continuous casting preferably of steel slabs with an a submerged melt outlet and use of casting powder incorporates a submerged melt outlet pipe (8) with a flow cross section (8.4) and an outlet cross section (8.3.1). It further incorporates freely movable narrow-side plates (1.3), and broad-side plates (1) which are plane in the direction of the mould length and are concave with a central symmetry in the direction of the mould with. The broad-side plates are additionally provided with a funnel section (5) corresponding to the cross section (8.1) of the melt outlet pipe at least in the melt level zone. This funnel section is at least partially reduced towards the mould outlet.

    Abstract: The production of continuous billets for continuous rolled products such as wire, rods, etc. in a continuous casting installation with a mould (1) is characterised by the fact that at the beginning of solidification the metal in the mould has a round or oval cross section (6), while at the exit from the mould it has a polygonal or profiled cross section (8, 8.1) with an approximately length of the circumference. Also claimed is a continuous casting installation for use in the above process.

    Abstract: Continuous casting process has strand cross-section reduction during strand solidification. The strand is cast in an oscillating mould and subjected to a linear cross-section reduction over a minimum length of the strand guide immediately below the mould, followed by a further "soft reduction" over the remaining strand guide up to a point close to full strand solidification. A corresponding casting plant is also claimed.

    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.

    Abstract: A method and apparatus forproducing coated slabs of metal, particularly strips of steel, in which a metal slab is guided through the bottom of a vessel filled with molten metal having the same or different composition as the metal slab, wherein the dwell time of the metal slab is selected in dependence on the melting bath level, the casting speed, the metal slab thickness and the preheating temperature of the metal slab in such a way that the molten metal deposited on the metal slab has a desired thickness of a multiple of the initial thickness of the metal slab, and wherein the metal slab with the layer crystallized onto the metal slab is subjected to a smoothing pass after emerging from the melting bath. The smoothing pass is carried out when the surface temperature of the crystallized slab is smaller than the solidus temperature of the melting bath and, thus, at least the surface of the crystallized layer is solidified.
