    摘要: The taper of narrow faces of a plate-type mold is controlled for the production of steel castings in slab form, wherein the plates of the mold are cooled by a liquid coolant and wherein the narrow faces can be adjusted between wide faces of the mold. Initially, the temperature of the coolant is measured at a coolant outlet of each plate of the mold. A cooling surface-related specific temperature value is then formed from each measured temperature. The specific temperature values of opposite plates are compared. The specific temperature values of each plate are compared with the specific temperature values of the adjoining plates. When a difference between the specific temperature values occurs, an adjustment value having a magnitude of the difference in values is applied to a drive of the narrow face which provides the lower temperature value, such that the taper of the narrow face is increased.

    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 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.
