    摘要： A method of continuously casting steel in which a melt is introduced through a movable immersion nozzle. The method includes the steps of controlling the start of the casting process in connection with the withdrawal of the casting by starting the withdrawal of the casting upon reaching a desired height of the surface of the steel in the mold, and driving the casting from the mold at a desired casting removal speed via a control element in a predetermined manner. Further, the method includes measuring the position of the bath level as it ascends in the mold during the continuous casting and adjusting the position of the immersion nozzle in relation to the ascending bath level from a first position to a desired operating position by changing the position of the distributor. Lastly, the method includes determining the desired operating position of the immersion nozzle with respect to the upper edge of the mold as a function of the temperature of the steel melt, the quality of the steel, the K-value of the solidification of the casting and the bath level, so as to establish, during the casting, a spacing of the outer lower edge of the immersion nozzle between a solidification front of the casting and the bath level.

    摘要： A method for continuous casting of thin slab ingots with reduced thickness following immediately the casting particularly of steel under utilization of a mold which is open at the bottom and under further utilization of roller pairs arranged along the withdrawal path, at least some of them are driven and at least some of the rollers are hydraulically adjustable perpendicular from the path so as to act as ingot deforming rolls. The invention is further improved by determining the speed of driven rollers, and the pressure force of adjustable roller pairs acting against the ingot and providing feedback control for the speed and the force. Additionally, providing a master control action for the speed control such that a point of solidification is dynamically maintained in a particular geometric position as far as the passing ingot is concerned; and by limiting the adjustment of rollers as far as the gap between pairs of such rollers is concerned downstream from that point.

    摘要： Molten steel is poured into a water cooled continuous casting mold in which the steel solidifies partially with the formation of a strand having a length and a peripheral shell. The strand has a cross-sectional surface area with one of a round shape, an oval shape and a polygonal shape having more than four sides. Additionally, the strand has a minimum circumference of 200 mm. The cross-sectional surface area of the strand leaving the mold is then reduced using rolls before the strand fully solidifies. The reducing includes deforming the strand into a polygonal shape having at least four corners while maintaining the circumference as well as the length of the strand at the peripheral shell constant.

    摘要： A liquid-cooled plate mold with adjustable width for the continuous casting of billets from steel in the form of slabs, particularly for a slab thickness of less than 100 mm. The shape-imparting broad side plates (1) and narrow side plates (2) of the ingot mold are constructed in the direction of their transverse extension so as to increase in cross section for the billet, while the narrow side plates (2) extend substantially parallel to one another along the height of the ingot mold. Further, the broad side plates (1) are constructed so as to be concave at least in a region (3) of smallest slab width in such a way that, in cross section, the apex height (13) of the ingot mold wall forming a curve has a determined height relative to a rectangle inserted in the drawing. The shape of the billet side plates at the billet outlet end (5) corresponds to the billet format to be produced.

    摘要： An immersion nozzle (2) for metallurgical recipients, in particular for a reservoir arranged upstream of a continuous casting ingot mould, has an interchangeable discharge pipe (2) which can be attached in a leakproof manner on or in a perforated brick (1). To improve the flow conditions and hence the efficiency of the casting, the inlet side of the nozzle comprises an upper elongated section (12) in the form of a tubular shaft (11) which expands conically downward to a given plane and which is narrow in a plane perpendicular to the given plane. A second elongate section (13) ends in an elongated transverse flow section of given dimensions.

    摘要： A method for continuous casting metal products under utilization of a mold and pouring molten metal into the mold to obtain a flat stock with a thickness below 100 mm, includes withdrawing the partially solidified casting by at least one roll pair which reduce the thickness of the stock upstream from complete solidification by at least 10% but not more than 70% while further reduction in thickness by at least 30% obtains downstream from complete solidification is improved by requiring that the product being cast has a thickness not below 50 mm; that exclusively internally cooled rollers are used for obtaining the reduction; and that the thickness is reduced downstream from the complete solidification at a point where the temperature is only little below the solidus temperature particularly in the case of steel being a temperature between 1500 and 1200 degrees C.

    摘要： Molten metal is introduced into a tubular mold and is withdrawn from the mold in the partly solidified state. There is included a sensor to measure the behavior of the metal strand as close as possible to the mold in order to control or regulate the drive unit for the withdrawal of the strand on a continuous casting machine. For a more precise determination of the actual conditions, the movement of the strand is measured in an area close as possible to the point where the strand leaves the mold. The measurement of the movement may be made in a non-contact and non-delayed manner by the sensor which responds to radiation. The sensor is designed and positioned so that it produces an evaluatable measurement signal in response to the displacement-time behavior of the strand. The measurement signal is transmitted to a display unit and/or evaluation unit for adjustment of the drive unit in order to obtain the desired speed of withdrawal.
